ios - iPhone - 检测触摸并取消触摸？

Question

我正在检测 UIView 上的触摸。在某些情况下，我希望能够取消触摸，以便 TouchsEnded 不会被调用。但是，touchesEnded 总是会被调用并不重要？

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
   if (SOMETHING_SPECIAL)
   {
      [super touchesCancelled:touches withEvent:event];
   }
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
   //I don't want it to get here if touches were canceled how can i do this?
}

- 在 TouchsEnded 中，我如何确定触摸是否被取消？

Answer 1

无论您的触摸是否被取消，

TouchesEnded 都会总是被调用，所以我建议改为确切地说:

   if (SOMETHING_SPECIAL)
   {

   }

在你的:

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
