Question

我的应用程序中有一个自定义UITextField，

class UnderLinedText: UITextField {

    override func layoutSubviews() {
        super.layoutSubviews()
        let border = CALayer()
        let width = CGFloat(1.0)
        border.borderColor = UIColor(red:0.21, green:0.13, blue:0.34, alpha:1.00).cgColor
        border.frame = CGRect(x: 0, y: self.frame.size.height - width, width:  self.frame.size.width, height: self.frame.size.height)
        border.borderWidth = width
        self.layer.addSublayer(border)
        self.layer.masksToBounds = true

    }


    override init(frame: CGRect) {
        super.init(frame: frame)
        self.textAlignment = .center
        self.borderStyle = .none
        self.isEnabled = true
        self.isUserInteractionEnabled = true
        self.font = UIFont(name: "HelveticaNeueLT-Regular", size: 20)
    }

    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }


}

我将其添加到我的视图控制器中，但无法正常工作（无法对其进行文本编辑）

class CommercialOrder: UIViewController , UITextFieldDelegate{

let bid = UnderLinedText()

override func viewDidLoad() {
        super.viewDidLoad()

        updateUI()

        bid.delegate = self

    }

 func updateUI(){
        self.view.backgroundColor = .white
        self.view.addSubview(scrollView)
        scrollView.addSubview(contentView)
        scrollView.showsVerticalScrollIndicator = false
               scrollView.autoPinEdgesToSuperviewSafeArea()
               contentView.autoPinEdgesToSuperviewEdges()
               contentView.autoMatch(.width, to: .width, of: view)
                contentView.addSubview(header)
                contentView.addSubview(bid_title)


        bid.autoPinEdge(.top, to: .bottom, of: bid_title, withOffset: 10)
        bid.autoPinEdge(toSuperviewEdge: .trailing, withInset: 20)
        bid.autoPinEdge(toSuperviewEdge: .leading, withInset: 20)
        bid.autoSetDimension(.height, toSize: 50)

        bid.text  = "Reciever mail"
}

我什至还添加了 UITextFieldDelegate ，将 isEnabled 和 isUserInteractionEnabled 设置为true，它仍然不起作用

任何帮助将不胜感激

Answer 1

希望能帮助别人，我的问题是contentView没有高度，这会影响滚动（视图不可滚动），因此它不会发生触摸事件，只需将高度或约束添加到contentView的最后一个视图的底部就像我的情况下一样

button.autoPinEdge(toSuperviewEdge: .bottom, withInset: 30)

就这样

Swift自定义UITextField不可编辑
