Question

我正在尝试开发Mapkit应用。这张地图上有一张地图，很多注释。如果我触摸其中一个注释，我的应用程序将从故事板显示自定义弹出窗口。如果我在弹出窗口处于活动状态时触摸视图上的其他位置，则弹出窗口将消失，没有任何问题。

但是，如果我触摸其中一个注释并将我的手指移出注释而不释放我的手指，我就会收到错误。

Answer 1

这个答案已经很晚了，但对于那些寻找解决方案的人：尝试创建一个storong属性来保存这个popover，然后在贴上地图附件时使用self.popover引用使用内容初始化它

HandleLongPress：UIPopoverController dealloc到达，而popover仍然可见
