Swift3 添加约束后,点击手势不起作用
在添加约束之前,我的代码工作得非常好。一旦添加了约束,点击手势似乎就不起作用了。 我的代码如下:Swift3 添加约束后,点击手势不起作用,swift3,uiscrollview,uitapgesturerecognizer,Swift3,Uiscrollview,Uitapgesturerecognizer,在添加约束之前,我的代码工作得非常好。一旦添加了约束,点击手势似乎就不起作用了。 我的代码如下: //this is in viewDidLoad() containerView.translatesAutoresizingMaskIntoConstraints = false scrollView.addSubview(containerView) self.view.addSubview(scrollView) if
//this is in viewDidLoad()
containerView.translatesAutoresizingMaskIntoConstraints = false
scrollView.addSubview(containerView)
self.view.addSubview(scrollView)
if #available(iOS 11.0, *) {
let top = NSLayoutConstraint.init(item: containerView, attribute: .top, relatedBy: .equal, toItem: self.view.safeAreaLayoutGuide, attribute: .top, multiplier: 1.0, constant: 0.0)
let leading = NSLayoutConstraint.init(item: containerView, attribute: .leading, relatedBy: .equal, toItem: self.view, attribute: .leading, multiplier: 1.0, constant: 0.0)

let height = NSLayoutConstraint.init(item: containerView, attribute: .height, relatedBy: .equal, toItem: nil, attribute: .notAnAttribute, multiplier: 1.0, constant: 60.0)
NSLayoutConstraint.activate([top, leading, trailing, height])
} else {
// Fallback on earlier versions
}
self.automaticallyAdjustsScrollViewInsets = false
//This is inside a function where I create subviews
containerView.addSubview(DiaryList)
let tapGesture = AddMyTapGesture(target: self, action: #selector(handleTap))
tapGesture.title = date
tapGesture.titleFormat = dateFormat
DiaryList.addGestureRecognizer(tapGesture)
DiaryList.isUserInteractionEnabled = true
//this is the tap gesture
@objc func handleTap(sender: AddMyTapGesture) {
print("tapped")
}
有什么解决办法吗?我也有同样的问题,在寻找答案
