will be helpful for those in need Because every Gem instance extend CCTargetedTouchDelegate and register touch dispatcher, only the highest or latest added will be triggered.
So what the correct way is implement CCTargetedTouchDelegate in HelloWorld class, and when touch occur, check which Gem is touched by touch point.

wish helps you The CCNode class which is the parent of the CCSprite class has a boundingBox property of type CGRect. Using this property of the player and target objects you can check for collisions using...
code :
if (CGRectIntersectsRect(player.boundingBox, target.boundingBox) {
    // Kaboom...

I wish did fix the issue. I'm trying to create a program where when the user touches the screen, a sprite will appear. However, if the user keeps their finger on that Sprite, the sprite will grow bigger until the user lets it go. , Make sure you enabled touch:
code :
    [super onEnter];

      self.touchEnabled = YES;
- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
    UITouch *myTouch = [touches anyObject];
    CGPoint touchLocation = [myTouch locationInView:[myTouch view]];
    touchLocation = [[CCDirector sharedDirector] convertToGL:touchLocation];

    if(CGRectContainsPoint([redBall boundingBox], touchLocation))
        growForever = [CCRepeatForever actionWithAction: [CCScaleBy actionWithDuration: .5 scale: 1.2]];
        [growForever setTag:1];
        [redBall runAction:growForever];

I wish this helpful for you In a PJSIP project (Windows 32 Bit MFC/C++) we are working with SIP server to show the incoming video call. Since using SDL / DirectShow (DirectX) layers, the SDL creates his own window to show incoming video (it works). My config_site.h looks like : , Workaround found (quick & dirty) - FindWindow helps (:
code :
CWnd* pWnd = mainView->GetDlgItem(IDC_STATIC_CTRL);
RECT rectWin;
::GetWindowRect(pWnd->m_hWnd, &rectWin);

HWND hWnd = FindWindow( _T("SDL_app"), NULL);

        rectWin.right - rectWin.left,
        rectWin.bottom - rectWin.top,
