我正在与Replaykit一起使用来录制屏幕..并使用以下代码从录制中排除录像机UIButton ...效果很好。录制视频后，我将显示警报并提供编辑或删除的选项。当选择编辑并取消时，我将以rootviewcontroller的身份进入主视图。
问题：取消两次后...按钮位置更改并设置为视图的左上角（buttonWindow）
码：
func addButtons( button1: UIButton) {
self.buttonWindow = UIWindow(frame: self.view.frame)
self.buttonWindow.rootViewController = HiddenStatusBarViewController()
self.buttonWindow.rootViewController?.view.addSubview(button1)
self.buttonWindow.rootViewController?.view.updateConstraintsIfNeeded()
self.buttonWindow.makeKeyAndVisible()
}
override func viewDidLayoutSubviews() {
print(3)
self.videoBtn.frame = (CGRect(x: 155, y: 575, width: 65, height: 65))
}
func startRecording() {
DispatchQueue.main.async {
// Update UI
self.addButtons(button1: self.videoBtn)
}
self.videoBtn.setImage(UIImage(named:"video capture"), for: .normal)
self.videoBtn.tintColor = .red
guard recorder.isAvailable else {
print("Recording is not available at this time.")
self.videoBtn.tintColor = .white
return
}
recorder.isMicrophoneEnabled = true
recorder.startRecording{ [unowned self] (error) in
guard error == nil else {
print("There was an error starting the recording.")
self.videoBtn.tintColor = .white
return
}
print("Started Recording Successfully")
self.isRecording = true
}
}
func stopRecording() {
self.videoBtn.tintColor = .white
recorder.stopRecording { [unowned self] (preview, error) in
print("Stopped recording")
guard preview != nil else {
print("Preview controller is not available.")
return
}
let alert = UIAlertController(title: "Recording Finished", message: "Would you like to edit or delete your recording?", preferredStyle: .alert)
let deleteAction = UIAlertAction(title: "Delete", style: .destructive, handler: { (action: UIAlertAction) in
self.recorder.discardRecording(handler: { () -> Void in
print("Recording suffessfully deleted.")
})
})
let editAction = UIAlertAction(title: "Edit", style: .default, handler: { (action: UIAlertAction) -> Void in
preview?.previewControllerDelegate = self.buttonWindow.rootViewController as? RPPreviewViewControllerDelegate
self.buttonWindow.rootViewController?.present(preview!, animated: true, completion: nil)
})
alert.addAction(editAction)
alert.addAction(deleteAction)
self.buttonWindow.rootViewController?.present(alert, animated: true, completion: nil)
self.isRecording = false
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let rootController = storyboard.instantiateViewController(withIdentifier: "ViewController")
let app = UIApplication.shared
app.keyWindow?.rootViewController = rootController
}
DispatchQueue.main.async {
// Update UI
}
}
func previewControllerDidFinish(_ previewController: RPPreviewViewController) {
dismiss(animated: true)
}
谢谢 ：）
最佳答案
我通过删除自动布局解决了这个问题！这样就可以了。谢谢！
如果您想使用自动布局？那么下面的代码就可以了！
self.buttonWindow.addConstraint(NSLayoutConstraint(item: button1, attribute: NSLayoutAttribute.centerX, relatedBy: NSLayoutRelation.equal, toItem: self.buttonWindow, attribute: NSLayoutAttribute.centerX, multiplier: 1, constant: 0))
self.buttonWindow.addConstraint(NSLayoutConstraint(item: button1, attribute: NSLayoutAttribute.bottom, relatedBy: NSLayoutRelation.equal, toItem: self.buttonWindow, attribute: NSLayoutAttribute.bottom, multiplier: 1, constant: -50))
