Swift2 Swift 2-fileURLWithPath返回零

我正在尝试使用

MPMoviePlayerController

加载视频。我已经在我的项目中添加了该文件，还将其添加到构建阶段“复制捆绑资源”

当我调用函数打开视频时，我可以看到路径已经打印出来，但是应用程序在“fileURLWithPath”上崩溃

我做错了什么？

.mp4

苍蝇可玩吗

 func firstView(){

        if let filePath  = NSBundle.mainBundle().pathForResource("firstVideo", ofType: "mp4") {

            print(filePath)
//PRINTS: /var/mobile/Containers/Bundle/Application/B93BB049-DA87-4D89-AEBE-A5C92C01726E/MyApp.app/firstVideo.mp4

            firstMoviePlayer!.contentURL = NSURL.fileURLWithPath(filePath) // fatal error
        }


        firstMoviePlayer!.repeatMode = .None
        firstMoviePlayer!.controlStyle = MPMovieControlStyle.Embedded

        firstMoviePlayer!.view.frame = FirstTimeVideoView.frame
        FirstTimeVideoView.addSubview(firstMoviePlayer!.view)

        firstMoviePlayer!.play()


    }

您只需更改：

if let filePath  = NSBundle.mainBundle().pathForResource("firstVideo", ofType: "mp4") {

            print(filePath)
//PRINTS: /var/mobile/Containers/Bundle/Application/B93BB049-DA87-4D89-AEBE-A5C92C01726E/MyApp.app/firstVideo.mp4

            firstMoviePlayer!.contentURL = NSURL.fileURLWithPath(filePath) // fatal error
        }

谢谢，但我得到错误：无法转换NSURL？要打印：file:///var/mobile/Containers/Bundle/Application/5B983567-AD2B-417A-B384-4218562E3796/myApp.app/firstVideo.mp4 但再次返回致命错误

if let filePath  = NSBundle.mainBundle().URLForResource("firstVideo", ofType: "mp4") {

            print(filePath)
//PRINTS: /var/mobile/Containers/Bundle/Application/B93BB049-DA87-4D89-AEBE-A5C92C01726E/MyApp.app/firstVideo.mp4

            firstMoviePlayer!.contentURL = NSURL.fileURLWithPath(filePath) // fatal error
        }
