Cannot show scene with Cocos2D when using UITabBarController
- by gw1921
Hi
I'm new to Cocos2D but am having serious issues when trying to load a cocos scene in one of the UIViewControllers mixed with other normal UIKit UIViewControllers.
My project uses a UITabBarController to manage four view controllers. Three are normal UIKit view controllers while one of them I want to use cocos2D for (to draw some sprites and animate them).
The following is what I've done so far. In the applicationDidFinishLaunching method, I initialize cocos2D to use the window and take the first tabbarcontroller view:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
if( ! [CCDirector setDirectorType:CCDirectorTypeDisplayLink] ) {
[CCDirector setDirectorType:CCDirectorTypeDefault];
}
[[CCDirector sharedDirector] setPixelFormat:kPixelFormatRGBA8888];
[CCTexture2D setDefaultAlphaPixelFormat:kTexture2DPixelFormat_RGBA8888];
[[CCDirector sharedDirector] setDisplayFPS:YES];
[[CCDirector sharedDirector] attachInView: window];
[[[CCDirector sharedDirector] openGLView] addSubview: tabBarController.view];
[window makeKeyAndVisible];
}
Then in the third UIViewController code (where I want to use cocos2D) I do this (note: the view is being loaded from a NIB file which has a blank UIView and nothing else):\
- (void)viewDidLoad {
[super viewDidLoad];
// 'scene' is an autorelease object.
CCScene *myScene = [CCScene node];
// 'layer' is an autorelease object.
MyLayer *myLayer = [MyLayer node];
// add layer as a child to scene
[myScene addChild: myLayer];
[[CCDirector sharedDirector] runWithScene: myScene];
}
However all I see is a blank white view and nothing else. If I call the following in viewdidLoad:
[[CCDirector sharedDirector] attachInView: self.view];
The app crashes complaining that CCDirector is already attached. Please help!
