ImagePicker关闭tabBar Nav Controller

Question

我有一个Tab Bar Controller，它提供了一个NavigationController。在其中一个ViewControllers中，我推动了这一点，我添加了imagePickerController来选择一张照片。当我取消或选择图片时，标签栏消失...我试图找到答案，但我找不到引用我特定问题的答案。

这是我的图像选择器方法

    @IBAction func attachImageBtnTapped(sender: AnyObject) {
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.PhotoLibrary){
            imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
            imagePicker.modalPresentationStyle = UIModalPresentationStyle.CurrentContext
            self.presentViewController(imagePicker, animated: true, completion: nil)
        }
    }

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        attachImageBtn.backgroundColor = UIColor.greenColor()
        dismissViewControllerAnimated(true, completion: nil)
    }

我该如何避免这种情况？我试着看看我是否将tabar设置为隐藏在viewWillAppear中，但是没有。

任何想法，任何帮助都将非常感谢！

我发现错误，我需要提供imagePicker控制器'OverCurrentContext'。

   @IBAction func attachImageBtnTapped(sender: AnyObject) {
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.PhotoLibrary){
            imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
            imagePicker.modalPresentationStyle = UIModalPresentationStyle.OverCurrentContext
            self.presentViewController(imagePicker, animated: true, completion: nil)
        }
    }
