我使用 MPMusicPlayerController 在我的应用程序中播放音频，并使用 RPScreenRecorder 录制屏幕。我遇到的问题是它只记录屏幕而不是应用程序中的音频。我遇到的另一个问题是，当我按下 previewController 的取消按钮时，它不会出于某种原因关闭视图。我究竟做错了什么？
@IBAction func stopTheRecordingAction(sender: AnyObject) {
stopTheRecording.hidden = true
recordButton.hidden = false
RPScreenRecorder.sharedRecorder().stopRecordingWithHandler { (previewController: RPPreviewViewController?, error: NSError?) -> Void in
if previewController != nil {
let alertController = UIAlertController(title: "Recording", message: "Do you wish to discard or view your gameplay recording?", preferredStyle: .Alert)
let discardAction = UIAlertAction(title: "Discard", style: .Default) { (action: UIAlertAction) in
RPScreenRecorder.sharedRecorder().discardRecordingWithHandler({ () -> Void in
// Executed once recording has successfully been discarded
})
}
let viewAction = UIAlertAction(title: "View", style: .Default, handler: { (action: UIAlertAction) -> Void in
self.presentViewController(previewController!, animated: true, completion: nil)
})
alertController.addAction(discardAction)
alertController.addAction(viewAction)
self.presentViewController(alertController, animated: true, completion: nil)
} else {
// Handle error
}
}
}
@IBAction func recordScreen(sender: AnyObject) {
recordButton.hidden = true
stopTheRecording.hidden = false
if RPScreenRecorder.sharedRecorder().available {
RPScreenRecorder.sharedRecorder().startRecordingWithMicrophoneEnabled(true, handler: { (error: NSError?) -> Void in
if error == nil { // Recording has started
} else {
// Handle error
}
})
} else {
// Display UI for recording being unavailable
}
}
func previewControllerDidFinish(previewController: RPPreviewViewController) {
previewController.dismissViewControllerAnimated(true, completion: nil)
print("dismiss")
}
