解雇UIImagePicker

Question

我正在使用以下方式解雇我的UIImagePicker：

func imagePickerControllerDidCancel(picker: UIImagePickerController!)
     {
      picker.dismissViewControllerAnimated(true, completion: nil)
     }

不幸的是，这也消除了下面的观点。我不希望这种情况发生。

我已经像这样加载了UIImagePicker：

let imagePicker: UIImagePickerController! = UIImagePickerController()


 @IBAction func uploadFromAlbumButton(sender : UIButton){
    let picker = UIImagePickerController()
    picker.allowsEditing = true
    picker.delegate = self
    presentViewController(picker, animated: true, completion: nil)
}

UIImagePicker下面的视图显示如下：

let newViewController = FulfilWishViewController();
newViewController.delegate = self
navigationController?.pushViewController(newViewController, animated: true)    

Answer 1

请检查您是否在viewwillappear（）中执行了任何代码。因为在解除了UIImagepickerController之后，它调用了父控制器的viewwillappear（）。

Answer 2

据我所知，你应该有下一个结构： 此外，SecondViewController应该具有故事板ID

您的ViewController.swift：

class ViewController: UIViewController, UINavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func didTapBtn1(sender: AnyObject) {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let secondViewController = storyboard.instantiateViewControllerWithIdentifier("SecondViewController")
        self.navigationController?.pushViewController(secondViewController, animated: true)
    }
}

SecondViewController.swift：

class SecondViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func didTapBtn2(sender: AnyObject) {
        let picker = UIImagePickerController()
        picker.allowsEditing = true
        picker.delegate = self
        presentViewController(picker, animated: true, completion: nil)
    }

    func imagePickerControllerDidCancel(picker: UIImagePickerController) {
        picker.dismissViewControllerAnimated(true, completion: nil)
    }
}

此代码已经过测试。我认为，问题在于调用SecondViewController。

<强>更新

如果您使用的是xib，那么您可以通过以下方式调用SecondViewcontroller：

@IBAction func didTapBtn1(sender: AnyObject) {
    let secondViewController = SecondViewController(nibName: "SecondViewController", bundle: nil)
    self.navigationController?.pushViewController(secondViewController, animated: true)
}

在ParentViewController中
