UIImagePickerController 在关闭时弄乱标签栏框架

Question

我正在尝试在 UITabBarController 内的 UIViewController 中显示 UIImagePickerController

SourceType 相机
MediaType kUTTypeMovie

显示 UIImagePickerController 没有问题，但是当关闭 TabBar 时，它会向下移动一半高度，它只是有时会发生...其他情况下它会完美关闭。

override func viewDidLoad() {

    var test: UIButton = UIButton(frame:CGRectMake(140, 200, 100, 100))
    test.backgroundColor = UIColor.redColor()
    test.addTarget(self, action:"presentCamera", forControlEvents: .TouchDown)
    self.view.addSubview(test)
}

func presentCamera(){
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera){
        imag.mediaTypes = [kUTTypeMovie]
        imag.delegate = self
        imag.sourceType = UIImagePickerControllerSourceType.Camera;
        imag.videoQuality = UIImagePickerControllerQualityType.TypeMedium
        imag.videoMaximumDuration = 120
        imag.allowsEditing = false
        self.presentViewController(imag, animated: true, completion:{println("showing")})
    }

}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    let library = ALAssetsLibrary()
    var videoTemp = info[UIImagePickerControllerMediaURL] as NSURL
    videoPath = videoTemp.relativePath
    UISaveVideoAtPathToSavedPhotosAlbum(videoPath, self, nil, nil)
    picker.dismissViewControllerAnimated(true, completion:{
        println("video selected")
    })    
}

func imagePickerControllerDidCancel(picker: UIImagePickerController) {
    picker.dismissViewControllerAnimated(true, completion:{
        println("canceled")
    })
}

它还显示此错误：

"Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates."

这里已经有人问过了：

Redbar Noticed when dismissing UIImagePickerController

我也注意到解雇时的红色状态栏，使用这个解决了：

您应该在 .plist

中将 "View controller-based status bar appearance" 值设置为 YES
