如何用swift将视频录制保存到文件目录？

Question

我已编写此代码来录制视频，并希望将filePath保存到文档目录，我该怎么做？

func startRecording() {
    var currentDateTime = NSDate()
    var formatter = NSDateFormatter()
    formatter.dateFormat = "MM-dd-yyyy, hh:mm:ss a"
    var recordingName = formatter.stringFromDate(currentDateTime) + ".mp4"
    var pathArray = [dirPath, recordingName]
    let filePath = NSURL.fileURLWithPathComponents(pathArray)

    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera) {
        videoRecorder = UIImagePickerController()
        videoRecorder.delegate = self
        videoRecorder.sourceType = UIImagePickerControllerSourceType.Camera
        videoRecorder.mediaTypes = [kUTTypeMovie]
        videoRecorder.videoMaximumDuration = 3600.0
        videoRecorder.startVideoCapture()
    }
}

之前我做过这个，你可以使用NSFileHandle来做到这一点

NSFileHandle（forWritingToURL：filePath，error：nil）

它对我有用。
