【问题描述】：
所以我已经在此工作了几天，但没有运气。我有一个由 xib 文件制成的自定义 UIView，我将它添加到我的 footerView 中。视图已显示，但它没有响应我添加到 ViewController 类中的标签的手势识别器。在 VC 中，我创建了一个 UIView 实例并将其添加到我的 tableView 中。
奇怪的是，当使用无障碍检查器时，它确实会读取标签
这里是容器视图
class AdviceCardWidgetContainerCurvedView: UIView {
struct Constants {
static let nibName = "ClariContainerView"
static let containerHeight: CGFloat = 169.0
static let curvedPercent: CGFloat = 0.2
}
let nibName = "ClariContainerView"
var clariView: UIView?
var clariTitle: String?
var clariQuestion: String?
@IBOutlet weak var clariTitleLabel: UILabel!
@IBOutlet weak var clariQuestionLabel: UILabel!
override init(frame: CGRect) {
super.init(frame: frame)
commonInit()
}
required init?(coder: NSCoder) {
super.init(coder: coder)
}
private func applyCurve(givenView view: UIView, curvedPercent: CGFloat) {
let shapeLayer = CAShapeLayer(layer: view.layer)
shapeLayer.path = self.pathForCurvedView(givenView: view, curvedPercent: curvedPercent).cgPath
shapeLayer.frame = view.bounds
view.layer.mask = shapeLayer
addSubview(view)
}
private func pathForCurvedView(givenView view: UIView, curvedPercent: CGFloat) -> UIBezierPath {
let path = UIBezierPath()
path.move(to: CGPoint(x: 0.0, y: 0.0))
path.addLine(to: CGPoint(x: 0.0, y: view.bounds.size.height))
path.addLine(to: CGPoint(x: UIScreen.main.bounds.width, y: view.bounds.size.height))
path.addLine(to: CGPoint(x: UIScreen.main.bounds.width, y: 0.0))
path.addQuadCurve(to: CGPoint(x: 0, y: 0), controlPoint: CGPoint(x: UIScreen.main.bounds.width / 2, y: view.bounds.size.height * curvedPercent))
path.close()
return path
}
private func commonInit() {
guard let clariView = loadViewFromNib() else { return }
clariView.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: containerHeight)
clariView.backgroundColor = .lightGray
applyCurve(givenView: clariView, curvedPercent: 0.1)
addSubview(clariView)
clariTitleLabel.text = "Ask TD Clari"
clariQuestionLabel.text = "What is my balance"
}
func loadViewFromNib() -> UIView? {
let bundle = Bundle(for: type(of: self))
let nib = UINib(nibName: Constants.nibName, bundle: bundle)
return nib.instantiate(withOwner: self, options: nil).first as? UIView
}
}
这就是我的视图控制器里面的东西
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var tableView: UITableView!
let curvedView = AdviceCardWidgetContainerCurvedView()
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewDidLayoutSubviews() {
curvedView.clariTitleLabel.accessibilityTraits = .button
curvedView.clariTitleLabel.isUserInteractionEnabled = true
curvedView.clariTitleLabel.backgroundColor = .red
curvedView.clariTitleLabel.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(footerLableTapped)))
tableView.tableFooterView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.width, height: 169))
tableView.tableFooterView?.addSubview(curvedView)
}
@objc func footerLableTapped() {
print("label tapped")
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell")!
cell.textLabel?.text = "1"
return cell
}
}
