issue accessing nativeView to add a UI element

dhbirchall

this is my first post here so hello everyone and thank you for this resource!

I am trying to access the nativeView to add a UI element on top (for gamecenter in an ios project.)

I have the following code in a method:

UIViewController *leaderboardParentViewController = [[UIViewController alloc] init];

        //access the main view
        UIView *sparrowView = (UIView *)self.stage.nativeView;

        [sparrowView addSubview:leaderboardParentViewController.view];

But I get this error: Property 'nativeView' not found on object of type 'SPStage *'

Can anyone help? I'm really stuck on this and quite new (very new) to sparrow.

I have looked but could not sort this out by looking at these articles although I feel that the answer lies in something similar:

Really sorry - I just found out the code that has been given to me to work on is running Sparrow 2. So the simple resolution was to use currentcontroller.view:

UIViewController *leaderboardParentViewController = [[UIViewController alloc] init];

        [Sparrow.currentController.view addSubview:leaderboardParentViewController.view];

however now I am getting a warning. Here is the method in full:

-(void)showLeaderBoard
{
    GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
    if (leaderboardController != nil)
    {
        leaderboardController.category = @"JPMHJ1";
        leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;
        leaderboardController.leaderboardDelegate = self;

        UIViewController *leaderboardParentViewController = [[UIViewController alloc] init];

        [Sparrow.currentController.view addSubview:leaderboardParentViewController.view];

        [leaderboardParentViewController presentModalViewController:leaderboardController animated:YES];

    }

the warning appears at "leaderboardController.leaderboardDelegate = self;"

the warning is: "Assigning to 'id<GKLeaderboardViewControllerDelegate>' from incompatible type 'InGame *const __strong'"

I seem to be able to get the gamecenter up if I do:

leaderboardController.leaderboardDelegate = Sparrow.currentController.delegate;

however then I still get the warning:

Assigning to 'id<GKLeaderboardViewControllerDelegate>' from incompatible type 'id<GLKViewControllerDelegate>'

and I am not sure now. I hope my resolution to my original issue helps someone although checking the version of the framework should have been the first thing I did!

any input is appreciated on the proper way to assign the delegate is much appreciated.

Thanks,

David

I have sorted out the issue. Here is my code for anyone who wants to implement gamecenter in Sparrow 2.

in header file:

#import <UIKit/UIKit.h>
#import <GameKit/GameKit.h>

@interface InGame : SPSprite<UIAccelerometerDelegate, GKLeaderboardViewControllerDelegate>{
...
...
...
}
-(void)openGameCenter;
-(void)addScore;
-(void)submitMyScore;
-(void)showLeaderboard;

in .m file:

@implementation InGame{
    GKLeaderboardViewController *leaderboardController;

}
...
...
...
-(void) openGameCenter
{
    [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error){
        if (error ==nil) {
            NSLog(@"Success");
           // [self SubmitScore];
            [self showLeaderBoard];
        } else {
            NSLog(@"Fail");
        }

    }];
}

-(void) SubmitScore{
    //This is the same category id you set in your itunes connect GameCenter LeaderBoard
    GKScore *myScoreValue = [[GKScore alloc] initWithCategory:@""];
    //
    myScoreValue.value = ;

    [myScoreValue reportScoreWithCompletionHandler:^(NSError *error){
        if(error != nil){
            NSLog(@"Score Submission Failed");
        } else {
            NSLog(@"Score Submitted");
        }

    }];
}

-(void)showLeaderBoard
{

        leaderboardController = [[GKLeaderboardViewController alloc] init];

        leaderboardController.category = @"";
        leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;

         leaderboardController.leaderboardDelegate = self;

    [Sparrow.currentController presentModalViewController:leaderboardController animated:YES];

}

- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController {

    [Sparrow.currentController dismissModalViewControllerAnimated:YES];

}

I don't know if this is best practice or not but it seems to work ok. All input welcome 🙂
