UITapGestureRecognizer 等待第二次点击，按钮缓慢 [英] UITapGestureRecognizer waiting for second tap, buttons slow

问题描述

我有一个 UITapGestureRecognizer 等待双击以将滚动视图缩小到原始级别.但是，有一种情况是我在滚动视图顶部添加了几个按钮.这些按钮的反应非常缓慢(缓慢)，因为一旦我点击一个按钮，应用程序就会等待第二次点击.如果没有出现，则按下按钮.

I have a UITapGestureRecognizer waiting for a doubletap to zoom out an scrollview back to the original level. However there is a situation that I add a couple of buttons on top of the scrollview. These buttons react very slow (sluggishly) because once I tap a button, the app waiting for the second tap. If this does not come, the button is pressed.

有人知道如何让按钮快速响应吗?我可以在按钮打开时暂时禁用 GestureRecogniser 吗?

Anyone have an idea on how to get the buttons to respond quickly? Can I temporarily disable the GestureRecogniser while the buttons are up?

干杯尼克

推荐答案

像这样过滤触摸按钮怎么样:

What about filtering touches on the buttons like so:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer 
       shouldReceiveTouch:(UITouch *)touch {
// Don't recognize taps in the buttons
return ((! [self.button1 pointInside:[touch locationInView:self.button1] withEvent:nil]) &&
        (! [self.button2 pointInside:[touch locationInView:self.button2] withEvent:nil]));
}

?
