Xcode HandleLongPress:UIPopoverController解除锁定，而popover仍然可见

我正在尝试开发一个Mapkit应用程序。有一张地图，地图上有很多注释。如果我触摸其中一个注释，我的应用程序将显示来自故事板的自定义弹出框。如果我在popover处于活动状态时触摸视图上的另一个位置，popover将毫无问题地消失

但是，如果我触摸其中一个注释并在不松开手指的情况下将手指移出注释，我就得到了错误

现在回答这个问题已经很晚了，但是对于那些寻找解决方案的人来说：尝试创建一个storong属性来保存这个popover，然后在地图附件上录制时使用self.popover引用来初始化它的内容
