Swift 3 Xcode 8中的FileManager和urlsForDirectory错误

Question

我刚刚从beta 3进入Xcode 8 beta 4,但出于任何原因我得到的错误一直没有错误或直到beta 4发布.这里是错误" Value of type 'FileManager' has no member 'urlsForDirectory'"

我的代码:

 func setupRecorder(){

        let audioSession:AVAudioSession = AVAudioSession.sharedInstance()

        //ask for permission
        if (audioSession.responds(to: #selector(AVAudioSession.requestRecordPermission(_:)))) {
            AVAudioSession.sharedInstance().requestRecordPermission({(granted: Bool)-> Void in
                if granted {
                    print("Permission Granted\n")

                    //set category and activate recorder session
                    do {
                        //----
                        let fileManager = FileManager.default
                        let urls = fileManager.urlsForDirectory(.documentDirectory, inDomains: .userDomainMask)
                        //----
                        let documentDirectory = urls[0] as URL
                        let soundURL = try! documentDirectory.appendingPathComponent("sound.m4a")

                        try audioSession.setCategory(AVAudioSessionCategoryPlayAndRecord)

                        try self.soundRecorder = AVAudioRecorder(url: soundURL, settings: self.recordSettings)

                       let micInput = try AVAudioRecorder(url
                        : soundURL, settings: self.recordSettings)


                        self.soundRecorder.prepareToRecord()
                        self.soundRecorder.updateMeters()



                    } catch {

                        print("Error Recording");

                    }

                }
            })
        }

    }

但唯一的部分是这一行:

                let urls = fileManager.urlsForDirectory(.documentDirectory, inDomains: .userDomainMask)

" 'Value of type 'FileManager' has no member 'urlsForDirectory'"

您只需将其更改urls(for:)为:

let documentDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
