Cocos2d iphone 在openGLView-cocos2d iphone的桌面上添加CCLabel

因此，在CCLayer中，我在openGLView中添加了一个ImagePicker/Camera，然后添加了一个UIButton——这一切都很好，但现在我想在这些元素上添加一个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。“”

移动UIImagePickerController顶部的COCO

好的，下面的呢？添加子视图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];

对不起，我想在UIImagePickerController顶部显示标签-将COCO移动到UIImagePickerController顶部感谢您的帮助，但它不会显示COCO元素-我有[CCDirector sharedDirector].openGLView.backgroundColor=[UIColor clearColor]；[CCDirector sharedDirector].openGLView.opaque=NO；glBlendFunc（GL_ONE，GL_ONE减去SRC_ALPHA）；glClearColor（0.0,0.0,0.0,0.0）；glClear（GL_颜色_缓冲_位| GL_深度_缓冲_位）；并添加了[[[CCDirector sharedDirector]openGLView].superview添加子视图：uip.view]；[[CCDirector sharedDirector]openGLView]removeFromSuperview]；[uip.cameraOverlayView添加子视图：[[CCDirector sharedDirector]openGLView]；请尝试使用glClearColor（1.0、0.0、0.0、1.0），以确保在cameraOverlayView上显示EagleView。这应该会让屏幕变红。我误解了！“uip.cameraOverlayView=[[CCDirector sharedDirector]openGLView]；”怎么样！？在调用openGLView的任何removeFromSuperview之前，请先获取superview，在CC_DIRECTOR_INIT（）之后应该可以。对不起，我想要的是在UIImagePickerController顶部显示标签-在UIImagePickerController顶部移动COCO感谢您的帮助，但它没有显示COCO元素-我有[CCDirector sharedDirector].openGLView.backgroundColor=[UIColor clearColor]；[CCDirector sharedDirector].openGLView.不透明=否；glBlendFunc（GL_ONE，GL_ONE _减去_SRC_ALPHA）；glClearColor（0.0,0.0,0.0）；glClear（GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER__BIT）；并添加[[CCDirector sharedDirector]openGLView].superview addSubview:uip.view]；[[CCDirector sharedDirector]openGLView]removeFromSuperview]；[uip.CameraOverlyView addSubview:[CCDirector sharedDirector]openGLView]；请尝试使用glClearColor（1.0,0.0,1.0）确保EagleView位于CameraOverlyView上。它会使屏幕变红。我误解了！怎么样“uip.cameraOverlayView=[[CCDirector sharedDirector]openGLView]；”！？请在调用openGLView的任何removeFromSuperview之前获取superview，在CC_DIRECTOR_INIT（）应该确定之后。
