【问题描述】：

我正在尝试在 UITabBarController 内的 UIViewController 中显示 UIImagePickerController

SourceType 相机
MediaType kUTTypeMovie

呈现 UIImagePickerController 没有问题，但是当关闭 TabBar 时，TabBar 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")
    })
}

它也显示此错误：

"对未渲染的视图进行快照会导致空白快照。确保您的视图之前至少渲染过一次屏幕更新后的快照或快照。”

这里已经问过了：

Redbar Noticed when dismissing UIImagePickerController

我还注意到关闭时的红色状态栏，使用此解决：

您应该在 .plist 中将“基于控制器的状态栏外观”值设置为 YES
