Question

所以在CCLayer中我将一个ImagePicker / Camera添加到openGLView然后是一个UIButton - 一切都很好，但现在我想在这些元素之上添加一个CCLabel（以及将来的CCSprites）。

    uip = [[UIImagePickerController alloc] init];
    uip.sourceType = UIImagePickerControllerSourceTypeCamera;
    uip.showsCameraControls = NO;
    uip.toolbarHidden = YES;
    uip.navigationBarHidden = YES;
    uip.wantsFullScreenLayout = YES;
    uip.cameraViewTransform = CGAffineTransformScale(uip.cameraViewTransform, CAMERA_TRANSFORM, CAMERA_TRANSFORM);

    [[[CCDirector sharedDirector] openGLView] addSubview:uip.view];

    arrowButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [arrowButton addTarget:self 
               action:@selector(arrowButtonClicked:)
     forControlEvents:UIControlEventTouchUpInside];

    UIImage *imgNormal = [UIImage imageNamed:@"btn_next_norm.png"];
    [arrowButton setImage:imgNormal forState:UIControlStateNormal];

    UIImage *imgPressed = [UIImage imageNamed:@"btn_next_pressed.png"];
    [arrowButton setImage:imgPressed forState:UIControlStateHighlighted];

    arrowButton.frame = CGRectMake(screenSize.width - 48.0, screenSize.height - 37.0, 48.0, 37.0);

    [[[CCDirector sharedDirector] openGLView] addSubview:arrowButton];

    CCLabelTTF* label = [CCLabelTTF labelWithString:@"Experience 1" fontName:@"Arial" fontSize:32];
    label.color = ccc3(0, 0, 0);
    CGSize size = [[CCDirector sharedDirector] winSize];
    label.position = CGPointMake(size.width / 2, size.height / 2);
   // [[[CCDirector sharedDirector] openGLView] addSubview:labe]; cant add to openGLView

您需要在openGLView下添加子视图UIView组件，如下所示，

[[[CCDirector sharedDirector] openGLView].superview addSubview:arrowButton];

然后，openGLView应该是透明的。 “Displaying an EAGLView with transparent background on a UIImageView”

修改

将Cocos移到UIImagePickerController
之上

好的，下面怎么样？ addSubview在UIImagePickerController的cameraOverlayView上的cocos2d视图（openGLView）。

[[[CCDirector sharedDirector] openGLView].superview addSubview:uip.view]; [[[[CCDirector sharedDirector] openGLView] removeFromSuperview]; uip.cameraOverlayView = [[CCDirector sharedDirector] openGLView];

此外，您需要Making Cocos2d Transparent。
