如何从捕捉每一个水龙头停止UITapGestureRecognizer？ [英] How do you stop UITapGestureRecognizer from catching EVERY tap?

问题描述

您好我有一个OpenGL的看法和我有一个标签栏。我使用的是自来水识别，挖掘在屏幕上不同的3D对象。在标签栏我有一个按钮，但它不工作，因为水龙头识别捕获这些水龙头了。我该如何停止？我已经尝试过这样的：

 
 - （BOOL）gestureRecognizer：（UIGestureRecognizer *）gestureRecognizer shouldReceiveTouch：（UITouch *）的触摸
{
  如果（[touch.view isKindOfClass：[的UIBarButtonItem类]]）返回FALSE;
  返回TRUE;
}
 

我想我莫名其妙地比较错误类新，因为当我调试它总是返回TRUE。

解决方案

  如果（[touch.view.superview isKindOfClass：[UIToolbar类]]）返回FALSE;

这是我得到了它的工作。在上海华是一个UIToolbar，大概 UIBarButtonIttem is视图毕竟。

Hello I have an opengl view and on that I have a tab bar. I'm using a tap recognizer to tap different 3d objects on screen. In the tab bar I have a button but it doesn't work because the tap recognizer catches these taps too. How do I stop this? I've already tried this:

- (BOOL) gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
  if ([touch.view isKindOfClass:[UIBarButtonItem class]]) return FALSE;
  return TRUE;
}

I think I am somehow comparing wrong classess because when I debug it returns TRUE always.

解决方案

  if ([touch.view.superview isKindOfClass:[UIToolbar class]]) return FALSE;

This is how I got it to work. The superview is a UIToolbar, probably UIBarButtonIttem is a view after all.
