[英]How to make my custom gesture recognizer class instances work simultaneously?
[英]create instance of custom xib class make gesture recognizer don't work
首先,我創建一個 .xib 文件並將其命名為RadioBtnView並將其連接到自定義 UIView 類:
class CheckBtnView: UIView {
@IBOutlet weak var mainView: UIView!
@IBOutlet weak var CheckBtn: UIButton!
@IBOutlet weak var checkDescription: UILabel!
var status = false {
didSet {
if status {
CheckBtn.backgroundColor = .orange
} else {
CheckBtn.backgroundColor = .clear
}
}
}
override init(frame: CGRect) {
super.init(frame: frame)
setupViews()
}
required init?(coder: NSCoder) {
super.init(coder: coder)
setupViews()
}
private func setupViews(){
Bundle.main.loadNibNamed("CheckBtnView", owner: self, options: nil)
addSubview(mainView)
mainView.frame = self.bounds
mainView.autoresizingMask = [.flexibleHeight,.flexibleWidth]
}
}
然后嘗試在 viewController 中以編程方式添加 RadioBtnView 的實例並向其添加手勢識別器:
let radio = RadioBtnView()
scrollContainerView.addSubview(radio)
radio.translatesAutoresizingMaskIntoConstraints = false
radio.topAnchor.constraint(equalTo: entry.bottomAnchor, constant: 15).isActive = true
radio.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 38).isActive = true
radio.isUserInteractionEnabled = true
let radioGesture = UITapGestureRecognizer(target: self, action: #selector(change(_:)))
radio.addGestureRecognizer(radioGesture)
但是 change(_:) 函數沒有響應似乎它沒有調用
這是為了以編程方式創建 xib 視圖還是其他什么?
我終於知道原因了......我只是刪除了radio.translatesAutoresizingMaskIntoConstraints = false
並添加了radio.frame = CGRect(x:50,y:100,width:120,height:20)
並且每一個思考工作似乎我們都可以不以編程方式添加 xib 視圖
