推荐答案

在你的手势识别处理程序中:

In your gesture recognizer handler:

 CGPoint location = [gestureRecognizer locationInView:gestureRecognizer.view];

如果需要，您可以指定不同的视图.

you could specify a different view, if you need it.

或者你也可以使用这个它属于 View 而不是 ViewController，看起来像这样:

or u can use this also It belongs in a View rather than ViewController, and would look something like this:

-(void)touchesBegan:(NSSet*)touches withEvent:(UIEvent*)evt {
  UITouch *touch=[touches anyObject];
  CGPoint pt=[touch locationInView:self];
  // ...make your button at 'pt'...
}
