UIScrollView，UIMenuController和LongPress手势
[英]UIScrollView, UIMenuController, and LongPress Gesture
问题描述
I have UIButtons added on the fly inside a UIScrollView and I also have a “LongPressGesture” attached to the button so when I tap the button for more than 1 second, a menu pops up (using UIMenuController). 
我在UIScrollView内动态添加了UIButton，并且还在按钮上附加了“ LongPressGesture”，因此当我点击按钮1秒钟以上时，会弹出一个菜单（使用UIMenuController）。
The problem is if I keep dragging my UIScrollView the menu does not move with the button which looks weird. 问题是，如果我一直拖动UIScrollView，菜单不会随着看起来很奇怪的按钮而移动。 But I am really looking for is to STOP the UIScrollView from scrolling once the UIMenuController appears. 但是我真正在寻找的是一旦UIMenuController出现，停止UIScrollView的滚动。
A perfect example is iMessage: You can drag all the messages up and down, but once you long press a message and the menu pops up, you CANNOT scroll anymore... iMessage就是一个完美的例子：您可以上下拖动所有消息，但是长按一条消息并弹出菜单后，就无法再滚动...

Can you not simply call -setScrollEnabled: on the scroll view and pass NO when you pop up your UIMenuController? 您不能简单地在滚动视图上调用-setScrollEnabled:并在弹出UIMenuController时传递NO吗？ You'd need to find a way to re-enable scrolling when the menu dismisses, but at least the scroll view would refuse to scroll until that happens... 您需要找到一种在菜单关闭时重新启用滚动的方法，但是至少滚动视图会拒绝滚动，直到发生这种情况为止...
