Question

我正在使用以前在其他项目中工作的代码，唯一的区别是这次我使用的是自定义精灵类似乎没有取消选择我在这里制作了一个关于问题的视频

-(void) ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{

NSSet *allTouch = [event allTouches];
UITouch *touch = [[allTouch allObjects]objectAtIndex:0];
CGPoint location = [touch locationInView:[touch view]];
location = [[CCDirector sharedDirector]convertToGL:location];


DragItems = [[NSMutableArray alloc]initWithObjects:

         Bubble01,
         Bubble02,
         Bubble03,
         Bubble04,
         Bubble05,
         Bubble06,
         nil];

for(int i = 0; i < [DragItems count]; i++)
{
sprite = (Bubble *)[DragItems  objectAtIndex:i];
//if(sprite.tag ==12 && CGRectContainsPoint([sprite boundingBox],location))
if(CGRectContainsPoint([sprite boundingBox], location))
{
    selectedSprite = sprite;
}
}
}


-(void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
//Move touched sprite
NSSet *allTouch = [event allTouches];
UITouch *touch = [[allTouch allObjects]objectAtIndex:0];
CGPoint location = [touch locationInView:[touch view]];
location = [[CCDirector sharedDirector]convertToGL:location];

selectedSprite.position = ccp(location.x, location.y);
NSLog(@"Position: %f %f",location.x, location.y);
}

-(void) ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
NSSet *allTouch = [event allTouches];
UITouch *touch = [[allTouch allObjects]objectAtIndex:0];
CGPoint location = [touch locationInView:[touch view]];
location = [[CCDirector sharedDirector]convertToGL:location];

selectedSprite = nil;

}

drag on CCLayer sometimes working

在rahul_send89的帮助下，我们解决了这个问题，首先，自定义类cclayer被更改为接受自己的触摸，然后在init中 [self setContentSize：[BackBubble boundingBox] .size];用来确定图层的大小（所以其他接触火，这可能会让我感到烦恼）

上面的链接包含所有代码。再次感谢您的帮助！

无法在拖动事件中取消选择我的CCSprite，selectedSprite = nil无法正常工作
