我正在尝试通过向窗口添加视图来执行吐司通知，它有一个进度条和一个按钮，如果它想在时间到期之前关闭，可以单击按钮。
发生的情况是按钮单击不起作用，它没有显示它已被单击。 我已经为视图和按钮设置了 isUserInteracionEnabled，我检查了视图层次结构以查看是否有任何视图阻塞了 toastView，但 toastView 位于所有其他视图之上，但按钮仍然无法单击。
这是我的 toastView 代码和 UIViewController 文件中的函数：
ToastView
class iFractalToastView: UIView {
private let tituloLabel = {
let label = iFractalTituloLabel(title: "STATUS", color: .PGF)
label.textAlignment = .center
label.font = UIFont(name: "MuseoSans-700", size: 14)
return label
}()
private let messageLabel = {
let label = iFractalBodyLabel(title: "", isBold: false)
label.textAlignment = .center
return label
}()
let progressBar = UIProgressView(progressViewStyle: .default)
let dismissButton = iFractalAlertButton(title: "OK")
var dismissAction: (() -> Void)?
private var message = String()
private var button = Bool()
init(message: String, button: Bool) {
super.init(frame: .zero)
self.isUserInteractionEnabled = true
dismissButton.isUserInteractionEnabled = true
dismissButton.addTarget(self, action: #selector(dismissButtonTapped), for: .touchUpInside)
self.message = message
self.button = button
self.translatesAutoresizingMaskIntoConstraints = false
iniciateSubViews()
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func setProgress(_ progress: Float) {
progressBar.setProgress(progress, animated: true)
}
@objc func dismissButtonTapped() {
print("ENTROUU dismissButtonTapped")
dismissAction?()
}
func imageWithColor(_ color: UIColor, size: CGSize = CGSize(width: 1, height: 1)) -> UIImage {
let format = UIGraphicsImageRendererFormat()
format.scale = 1
let image = UIGraphicsImageRenderer(size: size, format: format).image { rendererContext in
color.setFill()
rendererContext.fill(CGRect(origin: .zero, size: size))
}
return image
}
private func iniciateSubViews() {
addSubViews()
constraintsSubViews()
configurateSubviews()
}
private func addSubViews() {
addSubview(tituloLabel)
addSubview(messageLabel)
addSubview(progressBar)
if button == true {
addSubview(dismissButton)
}
}
private func constraintsSubViews() {
tituloLabel.translatesAutoresizingMaskIntoConstraints = false
messageLabel.translatesAutoresizingMaskIntoConstraints = false
progressBar.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
tituloLabel.topAnchor.constraint(equalTo: self.topAnchor, constant: 10),
tituloLabel.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 10),
tituloLabel.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -10),
messageLabel.topAnchor.constraint(equalTo: tituloLabel.bottomAnchor, constant: 10),
messageLabel.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 10),
messageLabel.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -10),
progressBar.topAnchor.constraint(equalTo: messageLabel.bottomAnchor, constant: 10),
progressBar.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 0),
progressBar.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: 0),
progressBar.heightAnchor.constraint(equalToConstant: 4)
])
if button == true {
dismissButton.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
dismissButton.topAnchor.constraint(equalTo: progressBar.bottomAnchor, constant: 10),
dismissButton.centerXAnchor.constraint(equalTo: self.centerXAnchor),
dismissButton.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: -10),
dismissButton.widthAnchor.constraint(equalToConstant: 100)
])
}
else {
NSLayoutConstraint.activate([
progressBar.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: -10)
])
}
}
private func configurateSubviews() {
backgroundColor = .TD90
layer.cornerRadius = 10
layer.borderColor = UIColor.PGF.cgColor
layer.borderWidth = 1.0
clipsToBounds = true
// Configure the message label
messageLabel.text = message
messageLabel.textAlignment = .center
messageLabel.numberOfLines = 0
// Configure the progress bar
progressBar.progress = 0.0
progressBar.progressImage = imageWithColor(.PGF)
//dismissButton.setTitle("OK", for: .normal)
//dismissButton.setTitleColor(.white, for: .normal)
dismissButton.clipsToBounds = true
}
}
UIViewController
func showToast(message: String, duration: TimeInterval = 60.0, button: Bool = false) {
let toastView = iFractalToastView(message: message, button: button)
// Configure toast view appearance
toastView.alpha = 0.0
toastView.translatesAutoresizingMaskIntoConstraints = false
if button == true {
toastView.dismissAction = {
UIView.animate(withDuration: 0.5, animations: {
toastView.alpha = 0.0
}) { _ in
toastView.removeFromSuperview()
}
}
}
// Add the toast view to the view controller's view
let window = UIApplication.shared.keyWindow!
window.addSubview(toastView)
// Set up constraints
if button == false {
NSLayoutConstraint.activate([
toastView.leadingAnchor.constraint(equalTo: window.leadingAnchor, constant: 10),
toastView.trailingAnchor.constraint(equalTo: window.trailingAnchor, constant: -10),
toastView.topAnchor.constraint(equalTo: window.topAnchor, constant: 41)
])
}
else {
NSLayoutConstraint.activate([
toastView.leadingAnchor.constraint(equalTo: window.leadingAnchor, constant: 10),
toastView.trailingAnchor.constraint(equalTo: window.trailingAnchor, constant: -10),
toastView.centerXAnchor.constraint(equalTo: window.centerXAnchor),
toastView.centerYAnchor.constraint(equalTo: window.centerYAnchor)
])
}
window.bringSubviewToFront(toastView)
// Animate the toast view appearance
UIView.animate(withDuration: 0.5, animations: {
toastView.alpha = 1.0
}) { _ in
// Animate the progress bar
let progress = Float(duration)
toastView.setProgress(progress)
// Animate the toast view disappearance
UIView.animate(withDuration: 0.5, delay: duration, options: .curveEaseOut, animations: {
toastView.alpha = 0.0
}) { _ in
toastView.removeFromSuperview()
}
}
}
问题出在这部分：
// Animate the toast view disappearance
UIView.animate(withDuration: 0.5, delay: duration, options: .curveEaseOut, animations: {
toastView.alpha = 0.0
}) { _ in
toastView.removeFromSuperview()
}
allowUserInteractiontoastView.layer.opacity如何解决：
// Animate the toast view disappearance
UIView.animate(
withDuration: 0.5,
delay: duration,
// Add allowUserInteraction
options: [.curveEaseOut, .allowUserInteraction],
animations: {
// Set alpha more then 0.01
toastView.alpha = 0.2
}) { _ in
toastView.removeFromSuperview()
}
