问题描述
我在我的ViewController中向我的主内容视图添加了一个 UITapGestureRecognizer ，以便在内容视图时关闭我的键盘轻拍。
I added a UITapGestureRecognizer to my main Content View in my ViewController to dismiss my keyboard when the content view is tapped.
问题是我的内容视图中有一个 UICollectionView ，并设置 UITapGestureRecognizer 拦截我的 UICollectionView 的点击。
The problem is that I have a UICollectionView inside my content view, and setting the UITapGestureRecognizer intercepts the taps of my UICollectionView.
我如何允许我的 UICollectionView 点击一下，以便再次触发 didSelectItemAtIndexPath 方法？
How do I allow my UICollectionView's taps to go through so that the didSelectItemAtIndexPath method will fire again?
func setupGestureRecognizer() {
let dismissKeyboardTap = UITapGestureRecognizer(target: self, action: "dismissKeyboard")
contentView.addGestureRecognizer(dismissKeyboardTap)
}
func dismissKeyboard() {
contentView.endEditing(true)
}
推荐答案
解决此问题的方法是添加 .cancelsTouchesInView = false 到你的 UITapGestureRecognizer 。
The way to solve this issue is by adding .cancelsTouchesInView = false to your UITapGestureRecognizer.
这允许其他视图中的触摸通过，例如a UITableViewCell 触摸。
This allows touches inside other views to go through, such as a UITableViewCell touch.
func setupGestureRecognizer() {
let dismissKeyboardTap = UITapGestureRecognizer(target: self, action: "dismissKeyboard")
dismissKeyboardTap.cancelsTouchesInView = false
contentView.addGestureRecognizer(dismissKeyboardTap)
}
func dismissKeyboard() {
contentView.endEditing(true)
}
