Cocos2d for iOS. How to determine that the touching has ended?

Question

If a notification(ie, a UIAlertView) appears while touching the screen (or home button is being pressed), ccTouchEnded will be called in game layer, but at the touch will already have ended.

How can I determine when the touch ends?

Answer 1

Check out the apple reference for UIResponder:

http://developer.apple.com/library/ios/#documentation/uikit/reference/UIResponder_Class/Reference/Reference.html

You probably want

touchesEnded:withEvent:

Hope this helps :)

Answer 2

-Make your scene conforms to protocol CCTargetedTouchDelegate -Add This line to init of your scene:

[[[CCDirector sharedDirector] touchDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:NO];

-Implement these functions:

- (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
 {
   return  YES;
 }
 -(void)ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event
  {
    //here touch is ended
  }

Answer 3

You should implement ccTouchesCancelled . This will occur whenever a touch event is interrupted.

Answer 4

Just check how many touch objects you have.

if([touches count] == 0)
{
  //NO TOUCHES
}
