Hello everyone,

I'm a newbie on both Sparrow and iPhone game development, so excuse me if this is a very basic question. I'm creating a simple game which needs access to the Game Center. I used the AppScaffold from the Sparrow distribution and made the class Game implement GKLeaderboardViewControllerDelegate. So, I also created a showLeaderboard and a leaderboardViewControllerDidFinish function.

When I call showLeaderboard after clicking a button, everything goes fine, the window appears with the scores. When I dismiss it using the "Done" button, the window is dismissed and disappears but I lose input on the window that was beneath. What am I doing wrong?

Code for showLeaderboard:

-(void) showLeaderboard { tempVC = [[UIViewController alloc] init]; GKLeaderboardViewController* leaderboardController = [[GKLeaderboardViewController alloc] init] autorelease]; if (leaderboardController != nil) { leaderboardController.leaderboardDelegate = self; [window addSubview:tempVC.view]; //Doesn't show up without this [tempVC presentModalViewController:leaderboardController animated:YES]; } }

Code for leaderboardViewControllerDidFinish:

-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController*) viewController { [tempCV dismissModalViewControllerAnimated:YES]; [tempCV removeFromSuperview]; }

What am I doing wrong here? :\

Thanks in advance!

I tried the answers provided here (http://forum.sparrow-framework.org/topic/uialertview-disrupting-sptouch-events) for similar cases but still no luck...

Hm ... to be honest, I can't think of anything right now that would cause that. Just an idea: have you tried adding the view to the sparrow view instead of the window?
UIView *sparrowView = self.stage.nativeView; // take care that self.stage != nil! [sparrowView addSubview:tempVC.view];
I don't know if this has something to do with it, but it might be worth the try.

Thanks for your reply! Yes, I tried that before... That also made the leaderboard window appear, but I lost all input after I dismissed the window. I noticed something funny though, I don't know if that can help... In despair, I tried to initialize the window.rootViewController by doing an alloc and init. When I did that, on startup, Sparrow immediately lost input. So, I'm guessing that whenever a ViewController is active, Sparrow loses control over the input somehow...

However, I tried releasing the leaderboard view controller and the tempVC after dismissing the window, but I still couldn't get the focus back... :\ Don't know what to do...

Hmm, maybe this might help... I took the Sparrow source code and integrated it directly (without compiling it to a library before) into my application. I followed the code until I entered the showLeaderboard function and everything went ok. Sparrow entered the processTouchEvent function correctly and the showLeaderboard was presented.

When I dismissed the leaderboard, however, whenever I touch the screen the processTouchEvent function is never called! I have very little experience with Objective-C but this sounds quite strange to me... :/

Try using this instead?
*i don't know if it'll work but i saw you where doing some stuff differently to how i would*

-(void) showLeaderboard{
    GKLeaderboardViewController* leaderboardController = [GKLeaderboardViewController alloc] init];
    if (leaderboardController != nil){
        leaderboardController.leaderboardDelegate = self;
        [self addSubView:YES];
    }
}
 
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController*) viewController{
    [viewController removeFromSuperview];
    [viewController release];
}

This 'should' work. However you want it animated so.

-(void) showLeaderboard{
    GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
    if (leaderboardController != nil){
        leaderboardController.leaderboardDelegate = self;
        leaderboardController.frame = CGRectMake(0,480,leaderboardController.frame.size.width,leaderboardController.frame.size.height);
        [self addSubView:YES];
        //Begin animation
        [UIView beginAnimations:@"LeaderBoards" context:NULL];
        [UIView setAnimationDuration:0.3f];
        [UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
        leaderboardController.view.frame = CGRectOffset(leaderboardController.view.frame, 0, -480);
        [UIView commitAnimations];
    }
}
 
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController*) viewController{
        [UIView beginAnimations:@"LeaderBoards" context:NULL];
        [UIView setAnimationDuration:0.3f];
        [UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
        viewController.view.frame = CGRectOffset(viewController.view.frame, 0, 480);
        [UIView commitAnimations];
        [self removeView:viewController];
}
 
-(void)removeView:(UIViewController*)viewController{
        static BOOL preRun = NO;
	if (preRun == NO) {
		[self performSelector:@selector(removeView:) withObject:viewController afterDelay:0.32f];
		preRun = YES;
	}
	else {
		[viewController removeFromSuperview];
		[viewController release];
	}
}

NOTE: this code was written in the forum's reply box rather then xcode so might not compile first time (i.e might have some errors).
*Also thanks alot for the sytax highlighting.

Hello!

Thanks for your replies! I managed to get it working by using a mix of everything that was said here. All the solutions in http://forum.sparrow-framework.org/topic/uialertview-disrupting-sptouch-events were required to make it work, but I also had to use some things from Daniel and freerunnering posts. If you want, I can post the code for future reference of anyone with the same problem.

Just one thing I was curious about. You (Daniel) used UIView *sparrowView = self.stage.nativeView;
What is the difference between this and just self.nativeView (where self is the Game class)? XCode accepted both, but the leaderboard starts blocking the input when using the second...

Great to hear that it works now!

Concerning your question: when "self" is the game class, then you can access the nativeView property directly (because then your "self" inherits from SPStage, anyway). But in all other classes, you have to get a reference to the stage first.

Sagito, please send the code if you can. I have the same problem and try to solve it. It might be useful for other users too.

OK guys, I did it with code below and it looks and works fine.

-(void) showLeaderboard:(SPEvent *)event;
{
 
    tempVC = [[UIViewController alloc] init];
 
    GKLeaderboardViewController* leaderboardController = [[[GKLeaderboardViewController alloc] init] autorelease];
    if (leaderboardController != nil)
    {
        leaderboardController.leaderboardDelegate = self;
		UIView *sparrowView = self.stage.nativeView; // take care that self.stage != nil!
		[sparrowView addSubview:tempVC.view];
		//[tempVC.view addSubview:leaderboardController.view];
        [tempVC presentModalViewController:leaderboardController animated:YES];
    }
}
 
- (void)animationDidStop:(NSString*)animationID finished:(BOOL)finished context:(void *)context
{
	for(UIView *subview in [tempVC.view subviews]) {
		[subview removeFromSuperview];
	}
	[tempVC.view.superview removeFromSuperview];
	[tempVC release];
}
 
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController*)viewController
{
	CGRect frame = viewController.view.frame;
	//[tempVC dismissModalViewControllerAnimated:YES];
	[UIView beginAnimations:@"curldoup" context:nil];
	[UIView setAnimationDelegate:self];
	[UIView setAnimationDuration:.5];
	[UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];
	//[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.stage.nativeView cache:YES];
	frame.origin.y = 480;
	viewController.view.frame = frame;
	[UIView commitAnimations];
	//[viewController.view removeFromSuperview];
 
}

I used the AppScaffold from the Sparrow distribution and made the class Game implement GKLeaderboardViewControllerDelegate

Silly question. How does one do that implementation? Probably more accurately, how do you implement both SPStage & GKLeaderboardViewControllerDelegate in the Game class?

I'm testing out the code above and I'm getting the following error:
"warning: class 'Game' does not implement the 'GKLeaderboardViewControllerDelegate' protocol"

Eerything seems to work but i'm getting the same warning of ipadfan.

Add <GKLeaderboardViewControllerDelegate> to your interface declaration and it'll remove the warning (you need to tell it want implements what delegate.

@interface Game : SPStage <GKLeaderboardViewControllerDelegate> {
//...
}

I thought so but i had an <UIAccelerometerDelegate> in that position and i'm gone in panic^^'

Now i replaced it with the GK one and the accelerometer still work but give the same kind of warning that was giving the GK one.... i know it's a basilar question but how to implement 2 delegates in the same class?

freerunnering, thanks so much. The error is gone.

I'll have to play with the code later today/tomorrow, etc. I'm no longer getting an error, but after the leaderboard/achivement board disappears from view the screen turns gray and nothing else happens. I must not have implemented Lestek's code faithfully.

(One change I did make was the line "frame.origin.y = 480;" I bumped it up to 1024, because I'm working on an ipad.)

(Mik -- I think you separate by a comma. When I was trying to add GKLeaderboardViewControllerDelegate I believe I saw that on google so I was trying <SPStage, GKLeaderboardViewControllerDelegate>. Close!)

Lol, so simple?

Yes, it worked, thanks a ton!

I'm also getting close. What cool features for comparatively little coding.

I haven't been able to shake the gray screen problem. My high scores submit and the leaderboard comes up. It also descends nicely but after the leaderboard leaves the screen, the screen decides to turn gray (not transparent).

Adding "NSLogs" throughout the code it looks like the "animationDidStop" function. Specifically, I don't think this line is much appreciated: "[tempVC.view.superview removeFromSuperview];" However, if I remove it, the screen is dimmed and unclickable.

I'm running Sparrow 0.8, designing for iPad and I assume I was supposed to add this to the .h file: "UIViewController *tempVC;".

Any ideas?

Does anyone have a "scaffold" project that authenticates Game Center, lets someone submit a score by clicking on a button and has a 'view leaderboard' button that I could download?

I downloaded Sparrow 1.1 (I was playing around in 0.8 still) and tried the same code as above. Instead of the screen turning grey, as outlined in my post above, the screen turned black.

Things were worse when I had the button linked directly to "showLeaderBoard" as the app crashed when the button was linked. (The "showLeaderBoard" action called from a function that checked a couple of things before passing the buck to that action.)

I got this error: "*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Attempting to begin a modal transition from <UIViewController: 0x6061730> to <GKLeaderboardViewController: 0x60cc540> while a transition is already in progress. Wait for viewDidAppear/viewDidDisappear to know the current transition has completed'"

I tried the following in my .h file: "UIViewController *tempVC;" and then "GKLeaderboardViewController *tempVC;".

I must be doing something wrong, but I just don't see it. Game Center logs me in. It allows me to submit scores. I just can't get the leaderboard to properly leave.

I'd like to test a working project and see if the same problems pop up.

I customized the scaffold project to support gamecenter, you can download the project here: http://www.justcode.it/iPhone/GCscaffold.zip

Please remember that i'm a noob in objective-c so this project is just the sum of what i learned in this thread ^^'

You will have to configure the info.plist to reflect your iTunesConnect bundle id and to change the name of your leaderboard inside game.m to make it fully work. GameKit is weaked linked in this sample.

Probaly it does not contains "best practices" but it works whitout warnings so, hope it helps!

Please make me know if you find something wrong in this code cause i'm going to use it too.

Thanks for your quick response. I have some good news and some bad news, but maybe it'll give enough clues that the particular error will

First, the good news.

You're right. If I make the appropriate changes, the project works wonderfully. The set up is very similar to what I did.

Next, the bad news.

The GCscaffold has a "TARGETED_DEVICE_FAMILY" of iPhone. When I switch that variable to iPad, the result described above occurs.

The score submits properly. The leaderboard comes up and retrieves the score property. The leaderboard exits through the bottom of the screen

I'm not sure which of the following code needs adjustment. To my novice eyes, none of it looks specific to iPhone v. iPad (except one small item).

 
-(void)showLeaderboard
{
 
    tempVC = [[UIViewController alloc] init];
 
    GKLeaderboardViewController* leaderboardController = [[[GKLeaderboardViewController alloc] init] autorelease];
    if (leaderboardController != nil)
    {
        leaderboardController.leaderboardDelegate = self;
		UIView *sparrowView = self.stage.nativeView; // take care that self.stage != nil!
		[sparrowView addSubview:tempVC.view];
		//[tempVC.view addSubview:leaderboardController.view];
        [tempVC presentModalViewController:leaderboardController animated:YES];
    }
}
 
-(void)animationDidStop:(NSString*)animationID finished:(BOOL)finished context:(void *)context
{
	for(UIView *subview in [tempVC.view subviews]) {
		[subview removeFromSuperview];
	}
	[tempVC.view.superview removeFromSuperview];
	[tempVC release];
 
}
 
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController*)viewController
{
	CGRect frame = viewController.view.frame;
	//[tempVC dismissModalViewControllerAnimated:YES];
	[UIView beginAnimations:@"curldoup" context:nil];
	[UIView setAnimationDelegate:self];
	[UIView setAnimationDuration:.5];
	[UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];
	//[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.stage.nativeView cache:YES];
	frame.origin.y = 480;
	viewController.view.frame = frame;
	[UIView commitAnimations];
	//[viewController.view removeFromSuperview];
}

I did change the 480 in "frame.origin.y = 480;" to 1024. Otherwise, I'm at a loss as to what else needs to get done.

Interestingly, if I change my development target to iPhone, it works as well.

Anyone have experience getting the Game Center integrated with an iPad only application?

I have no clue my friend, i actually tryied my code in the iPad simulator and i confirm the strange behaviour... ithink you'll need the help of the second level guys of the forum

I think I'm getting closer.

One further question: "[tempVC presentModalViewController:leaderboardController animated:YES];"

Is it possible to have tempVC rotate to a different orientation?

The gamecenter leaderboard overrides any manual setting. For instance, if I rotate on a sprite to upside down position (using the techniques in http://forum.sparrow-framework.org/topic/auto-orientation-on-ipad ) and call " [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationPortraitUpsideDown;". When the gamecenter leaderboard pops up, it flips the task bar to the other side and the leaderboard is upside down.

Using google, I saw mention that another framework that Game Center was keyed off of the keyboard orientation (see http://forum.unity3d.com/threads/59551-GameCenter-Plugin-Live!-Leaderboards-and-Achievements!/page22?s=7dc691d9f7145e9cf130f4d0e80558da ) -- at least that's what I interpret the post as saying. Anyone know how to change the keyboard orientation? I've assumed that that's what the "[UIApplication sharedApplication].statusBarOrientation ... " code does in the other thread, but it is vetoed.

My keyboard orentation seems to work well with this syntax:
[[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationLandscapeRight];
The keyboard that appear to login in GC is alwais in the correct orentation.

I've been playing around with this code on the iPad again. I'm getting a strange error I'm fairly certain I was getting before. On occasion the view doesn't update after the leaderboard disappears but will update once the leaderboard is displayed. (i.e., if there's a button that makes a circle move from one side of the screen to the other, the button doesn't seem to work until the leaderboard is displayed again).

I've tried all sorts of variations of the code above, but am not sure how to diagnose. Any thoughts?

-(void) showLeaderboard
{
    NSString *board = @"my_scoreboard";
    tempVC = [[UIViewController alloc] init];
    GKLeaderboardViewController* leaderboardController = [[[GKLeaderboardViewController alloc] init] autorelease];
    if (leaderboardController != nil)
    {
		leaderboardController.category = board;
		leaderboardController.leaderboardDelegate = self;
		UIView *sparrowView = self.stage.nativeView; // take care that self.stage != nil!
		[sparrowView addSubview:tempVC.view];
		//[tempVC.view addSubview:leaderboardController.view];
		[tempVC presentModalViewController:leaderboardController animated:YES];
		if(Flag_upsidedown == YES) {
			NSLog(@"Flip leaderboard upside down");
			leaderboardController.view.transform = CGAffineTransformMakeRotation(M_PI*1.00);
			[[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationPortraitUpsideDown animated:NO];
		}
    }
}
 
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController*)viewController
{
	[tempVC dismissModalViewControllerAnimated:YES];
	for(UIView *subview in [tempVC.view subviews]) {
		[subview removeFromSuperview];
	}
	for(UIView *subview in [self.stage.nativeView subviews]) {
		[subview removeFromSuperview];
	}
	// [tempVC.view removeFromSuperview];
	//[tempVC.view.superview removeFromSuperview];
	[tempVC release];
	if(Flag_upsidedown == YES) {
		[[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationPortraitUpsideDown animated:NO];
	}
}

I don't know if its of any help, but I had problems with displaying the dialog modally, too. In my case, the reason was an oddity of the view controller setup I had created. Here is a description of the problem. Probably yours is a different problem, but you never know ...

-- code from the original post of this thread starts here --

Code for showLeaderboard:
-(void) showLeaderboard { tempVC = [[UIViewController alloc] init]; GKLeaderboardViewController* leaderboardController = [[GKLeaderboardViewController alloc] init] autorelease]; if (leaderboardController != nil) { leaderboardController.leaderboardDelegate = self; [window addSubview:tempVC.view]; //Doesn't show up without this [tempVC presentModalViewController:leaderboardController animated:YES]; } }
Code for leaderboardViewControllerDidFinish:
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController*) viewController { [tempCV dismissModalViewControllerAnimated:YES]; [tempCV removeFromSuperview]; }
What am I doing wrong here? :\

-- Orignal post ends --

A lot of these posts failed to work for me. Some of the info is just wrong.

All that is needed to make the original example work is to change the last line of code to [tempCV.view removeFromSuperView];. Note the addition of '.view' to tempCV. This change results in proper event handling in the main application again.

The last post by ipadFan works, but if you check the debug output it's only doing what the one line of code I've included here does.

There may be some memory leaks and other rough edges with the original code, but you don't need a lot of the code in the examples above.

ntc490.. you deserve my total respect ... in fact, if you added a subview with:

[window addSubview:tempVC.view]; //Doesn't show up without this

The same you have to do to remove it.
Note that with the latest iOS SDK dismissing a view without specifying a block of code executed on completion is DEPRECATED. Thus, I found the right code to make the leader board vanish without any kind of problems:
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController*)viewController { [tempVC dismissViewControllerAnimated:YES completion:^(void) { [tempVC.view removeFromSuperview]; [tempVC release]; NSLog(@"leaderboard correctly dismissed"); }]; }
That makes sense!!! Thanks again.
I feel good, I feel fine.

Goin to smoke a cigarillo.

The middle and bottom errors indicate that you have not implemented showLeaderboard and authenticateLocalPlayer in your Game class.
