Showing a UIKit view during game in landscape mode

Hi everyone,

I'm sure this has already been discussed a few times, but I can't make it work based on what I've read so far, so I'm asking for assistance!

I would like to make a UIKit view appear when the player touches a specific SPButton on the Stage. I have designed this view and its UIViewController, and added the code to show it, using the Stage's nativeView.
Everything works fine, except that the UIView is shown in portrait mode, but my game is landscape-orientation only.
I've read somewhere on this forum that I have to use an intermediate UIView to make things work fine, but I didn't manage to do that. More specifically, I don't know how to configure this holder view so that the future views added to it will show in the right orientation.

Here's the current code that works but with the wrong orientation:
gameSettings.view.frame = CGRectOffset(gameSettings.view.frame, 0, 480); [UIView beginAnimations:@"animateSettingsWindowOn" context:NULL]; gameSettings.view.frame = CGRectOffset(gameSettings.view.frame, 0, -480); [self.nativeView addSubview:gameSettings.view]; [UIView commitAnimations];
Here's the code with a holder view, in this case nothing works (i.e. the UIView does not show):
// During init: holderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.width, self.height)]]; [self.nativeView addSubview:holderView]; ... // Does not work (gameSettings.view doesn't show up) gameSettings.view.frame = CGRectOffset(gameSettings.view.frame, 0, 480); [UIView beginAnimations:@"animateSettingsWindowOn" context:NULL]; gameSettings.view.frame = CGRectOffset(gameSettings.view.frame, 0, -480); [holderView addSubview:gameSettings.view]; [UIView commitAnimations];
Thank you very much!

Hi Romain,

mhm, this stuff can be tricky, I've struggled with that myself. One thing that is easy to miss is that 'self.nativeView' might return 'nil' if its called in the init-method of your game, because the game is not yet connected to the SPView object. Be sure to check that this isn't the case. If it is, add an additional method to your game class that is responsible for creating the holder view, and call it only after the game is connected to the SPView. (This is done in the application delegate).

A solution I use is to restructure the base project so that SPView resides as a subview within a UIViewController. If you start off with a view based project this makes it pretty easy.
So project setup ends up looking like this:
UIApplication
-- UIViewController
---- UIView (container)
------ UIView (overlay views to add and remove over SPView)
------ SPView (sparrow stuff)

As for auto rotating the view that you are adding you can subclass UIView and override addSubview:
- (void)addSubview:(UIView *)view{ [super addSubview:view]; view.transform = CGAffineTransformMakeRotation(SP_D2R(90)); // do any additional transformations like offset x position of the frame or what not }
You can then just use this class for your container view.

Hope that helps.

Hi,

Thank you for your replies.
I'm currently trying Daniel's solution, because after further checking, self.nativeView indeed was 0x0 when I was trying to add a subview.

So, I've created a connectHolderView method, which I'm trying to call from the application delegate class. However, when I do that, although I can see my Stage like before, it doesn't reply to events anymore. Is it because the (invisible) holder view is on top of it? How should I configure this UIView to not interfere with the game?

Here's the main part of the AppDelegate class (almost untouched):

- (void)applicationDidFinishLaunching:(UIApplication *)application
{
    SP_CREATE_POOL(pool);    
 
    [SPStage setSupportHighResolutions:YES];
    [SPAudioEngine start];
 
    Stage *stage = [[Stage alloc] init];
    mSparrowView.stage = stage;
    [stage connectHolderView]; // The new method call
    mSparrowView.multipleTouchEnabled = NO;
    mSparrowView.frameRate = 30.0f;
	mSparrowView.autoresizingMask = UIViewAutoresizingNone;
	mSparrowView.autoresizesSubviews = NO;
    [stage release];
 
    [mWindow makeKeyAndVisible];
    [mSparrowView start];
 
    SP_RELEASE_POOL(pool);
}

And here's the new connectHolderView method:

- (void)connectHolderView
{
	holderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.width, self.height)];
	[self.nativeView addSubview:holderView];
}

Thanks!

Ah, I think you're in luck: look at this forum post, where I describe how to configure the UIView so that touches go through to the SPView below. That should do it!!
