这是什么使无限循环？

我在UIView的子视图中遇到手势识别问题。我的子视图是一个可以通过UIPanGestureRecognizer拖动的视图 - 我知道该部分有效。但我有一个问题首先得到该视图。触及到我的UIView--而不是我希望他们去的子视图。我试着强制重定向触摸到我的这个目标代码视图：这是什么使无限循环？

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    NSLog(@"rT"); 
    [self.valueLabel touchesBegan:touches withEvent:event]; 
} 
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    NSLog(@"mT"); 
    [self.valueLabel touchesMoved:touches withEvent:event]; 
} 
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    NSLog(@"eT"); 
    [self.valueLabel touchesEnded:touches withEvent:event]; 
}

......但后来我的控制台都疯了 - 无限循环

我似乎无法图这一点。

任何帮助（在合理范围内...）

因为你在touchesBegan中调用touchesBegan – rdelmar 2013-02-09 00:26:52

您发布的代码进入一个循环，因为

valueLabel不响应touchesBegan:，touchesMoved:和touchesEnded: ... 这称为备份到你的代码。

这是一个无意的递归循环。

绝对放弃这种方法。你有没有试过valueLabel.userInteractionEnabled = YES？

你的触动被转发到self.label的superview自己。这导致无限递归。
