iOS TableView 长按手势去 didselectrowatIndexpath

Question

伙计们，我有显示图像的表格 View ，因此对于任何图像，点击都会在

中打开图像

didselectrowatIndexpath

所以我想添加一个长按手势所以我添加了

let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(longPressed(_:))) 
cell.baseview.addGestureRecognizer(longPressGesture) 

但每次我按住图像时，它都会使用 didselectrowat 方法打开图像，而不是使用长按方法。对于长按手势 Action ，我应该改变什么吗？

Answer 1

这是 Apple 对您问题的回答。

Managing Selections (Responding to Selections)
If the touch occurred in a control embedded in the row, it couldrespond to the action message sent by the control.

Understanding Responders and the Responder Chain
UIKit directs most events to the most appropriate responder object in your app. If that object does not handle the event, UIKit forwards it to the next responder in the active responder chain, which is a dynamic configuration of your app’s responder objects.

解决方案:
您在图像的用户交互方面存在问题。在 ImageView 上启用用户交互。

cell.baseview.isUserInteractionEnabled = true
