这里我用来从图库中获取视频并与音频合并，并将最终视频显示到屏幕。我使用MPMoviePlayerController显示合并的视频。在这里，我在MPMoviePlayerController的子视图上添加了一个按钮。当那个按钮点击我的视频应该在新播放器中播放，或者它也可能是一些视图控制器，
需要：
我尝试在屏幕上添加该视频播放器子视图上的按钮。但是无法执行操作方法
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
button = UIButton(type: UIButtonType.System) as UIButton
button.frame = CGRectMake(34, 449, 220, 106)
button.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(button)
button.hidden = true
}
这里的行动：
func buttonAction(sender:NSNotification?){
print("finishPreload");
}
这时我的合并视频完成了：
func exportDidFinish(session: AVAssetExportSession) {
if session.status == AVAssetExportSessionStatus.Completed {
let outputURL = session.outputURL
let library = ALAssetsLibrary()
if library.videoAtPathIsCompatibleWithSavedPhotosAlbum(outputURL) {
library.writeVideoAtPathToSavedPhotosAlbum(outputURL,
completionBlock: { (assetURL:NSURL!, error:NSError!) -> Void in
var title = ""
var message = ""
if error != nil {
title = "Error"
message = "Failed to save video"
} else {
// AVAsset *asset = AVAsset assetWithURL: outputURL
self.videoURL = outputURL!
self.mediaUI.dismissViewControllerAnimated(true, completion: nil)
self.videoPlayer = MPMoviePlayerController()
self.videoPlayer.contentURL = self.videoURL
self.videoPlayer.controlStyle = .Embedded
self.videoPlayer.scalingMode = .AspectFill
self.videoPlayer.shouldAutoplay = true
self.videoPlayer.view.frame = CGRectMake(34, 449, 220, 106)
self.view.addSubview(self.videoPlayer.view)
self.videoPlayer.play()
self.videoPlayer.prepareToPlay()
self.button.hidden = false
title = "Success"
message = "Video saved"
}
let alert = UIAlertController(title: title, message: message, preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Cancel, handler: nil))
self.presentViewController(alert, animated: true, completion: nil)
})
}
}
// activityMonitor.stopAnimating()
firstAsset = nil
secondAsset = nil
audioAsset = nil
}
我创建此按钮的原因是当我在屏幕上触摸我的视频播放器时，它应该在新播放器或下一个viewcontroller中播放视频。为此我保持按钮动作。但是不能做按钮动作方法。
谢谢！
注意：
如果它不可能。那么有任何替代解决方案 - 当我点击在我的屏幕上显示的合并视频时，它应该在另一个播放器中播放或在另一个新屏幕上播放
