UIImagePickerController视频录制在延迟或不工作后开始

I am working on a application which needs custome camera UI. SO I used Overlay view in ImagePickerController. User can switch between capture modes. (UIImagePickerControllerCameraCaptureMode.Video and UIImagePickerControllerCameraCaptureMode.Photo )

我正在开发一个需要自定义相机UI的应用程序。所以我在ImagePickerController中使用了Overlay视图。用户可以在捕获模式之间切换。 （UIImagePickerControllerCameraCaptureMode.Video和UIImagePickerControllerCameraCaptureMode.Photo）

My problem is when user swich capture mode from .Photo to .Video startVideoCapture() function is taking time (up to 5 seconds) to initialize the video capturing at firs or second time.

我的问题是从.Photo到.Video startVideoCapture（）函数的用户swich捕获模式需要花费时间（最多5秒）来初始化第一次或第二次的视频捕获。

Sometimes it does not save video on specified path..Photo mode is working fine. At starting I initialized imagePickerController with .Photo mode. And user could switch .Photo to .Video. I thought may be initializing .Video mode would have taken time. For this I initialize the imagePickerController with .Video mode and set a timer to change .video to .Photo mode in 4 seconds. While these 4 seconds user cannot see camera as I have added Loading screen to stop user interaction.

有时它不会在指定的路径上保存视频..照片模式工作正常。在开始时，我使用.Photo模式初始化了imagePickerController。用户可以将.Photo切换为.Video。我想可能正在初始化。视频模式需要时间。为此，我使用.Video模式初始化imagePickerController，并设置一个计时器，在4秒内将.video更改为.Photo模式。虽然这4秒钟用户无法看到相机，因为我已添加加载屏幕以停止用户交互。

But still problem persist. startVideoCapture() taking time to start recording for very first time. And sometimes it does not save video on specified path after recording.

但问题仍然存在。 startVideoCapture（）花时间开始第一次录制。有时它在录制后不会在指定的路径上保存视频。

Here is my code to save video in delegate method.

这是我在委托方法中保存视频的代码。

/**
*  Delegate method for media capture and save media
*/
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info:[NSObject : AnyObject]) {

    overlayView.bringSubviewToFront(preView)

    let mediaType = info[UIImagePickerControllerMediaType] as! NSString

    if mediaType.isEqualToString(kUTTypeMovie as NSString as String){
        let tempMedia = info[UIImagePickerControllerMediaURL] as! NSURL!
        let pathString = tempMedia.relativePath

        if pathString != nil {

            destinationPathForVideo = "\(UtilityManager.sharedInstance.kcache)/challengeRecordings/\(NSDate()).mp4"

            NSFileManager.defaultManager().createDirectoryAtPath(destinationPathForVideo.stringByDeletingLastPathComponent, withIntermediateDirectories: true, attributes: nil, error: nil)

            UtilityManager.sharedInstance.copyFileFromSourceTo( pathString, destinationPath: destinationPathForVideo )

            // Save Image


            imageCaptured = getThumbnailForVideoPath(pathString!)
            destinationPathForImage = "\(UtilityManager.sharedInstance.kcache)/challengeRecordings/\(NSDate()).png"
            let success = UIImagePNGRepresentation(imageCaptured).writeToFile( destinationPathForImage , atomically: true)

            Log(message:"Saved: \(success)")

            imageButton!.setImage(imageCaptured, forState: .Normal)
            imageView.image = imageCaptured

       }



}

This is my initializing code

这是我的初始化代码

    imagePicker            = UIImagePickerController()
    imagePicker.delegate   = self
    imagePicker.sourceType = .Camera
    imagePicker.showsCameraControls = false
    self.imagePicker.mediaTypes = [kUTTypeMovie, kUTTypeImage]
    self.imagePicker.videoMaximumDuration = 11
    self.imagePicker.videoQuality = UIImagePickerControllerQualityType.TypeMedium
    self.imagePicker.cameraFlashMode = .Off
    self.imagePicker.cameraCaptureMode = UIImagePickerControllerCameraCaptureMode.Video

Somebody please help.
