如何在選擇/拍攝後將圖像從相機/相機膠捲傳遞到新視圖？

Question

我已經添加了一個相機&照片庫到我的應用程序，但我想要做的是當有人選擇相機，拍照並選擇它時，我希望它將用戶引導到新的視圖控制器並顯示那裏的圖像，而不是在按鈕所在的當前視圖上？

我在Google上搜索過，但沒有找到任何清晰或迅速的東西，因爲我對ObjC沒有任何瞭解，所以我不確定我所看到的是否正確！

這裏是下面我當前的代碼：

override func viewDidLoad() { 
    super.viewDidLoad() 

    // Do any additional setup after loading the view. 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
} 


@IBAction func Camera(sender: AnyObject) { 

    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera) { 
    let imagePicker = UIImagePickerController() 
    imagePicker.delegate = self 
    imagePicker.sourceType = UIImagePickerControllerSourceType.Camera; 
    imagePicker.allowsEditing = false 
    self.presentViewController(imagePicker, animated: true, completion: nil) 
    } 
} 


@IBAction func Images(sender: AnyObject) { 

    let imageLoad = UIImagePickerController() 
    imageLoad.delegate = self 
    imageLoad.sourceType = UIImagePickerControllerSourceType.PhotoLibrary 
    imageLoad.allowsEditing = false 


    self.presentViewController(imageLoad, animated: true, completion: nil) 
} 


func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image:UIImage, editingInfo: [String : AnyObject]?) { 

    self.dismissViewControllerAnimated(true, completion: nil) 

}

Answer 1

基於以上的答案，你要設置圖像的圖像視圖，當你應試圖將圖像設置爲圖像視角的圖像，因此，它應該是：

func viewDidLoad() { 
    super.viewDidLoad() 

    // Because the self.image is an optional var, you need to unwrap it 
    if let image = self.image { 
     self.imageView.image = self.image 
    } 
} 

Answer 2

你只需要像分配給新的視圖控制器：

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image:UIImage, editingInfo: [String : AnyObject]?) { 

    self.dismissViewControllerAnimated(true, completion: nil) 

    let svc = self.storyboard!.instantiateViewControllerWithIdentifier("imageViewer") as! ImageViewController 
    svc.image = image 

    self.presentViewController(svc, animated: true, completion: nil) 
} 

，然後在imageViewerController：

func viewDidLoad() { 
    super.viewDidLoad() 

    // Because the self.image is an optional var, you need to unwrap it 
    if let image = self.image { 
     self.imageView.image = self.image 
    } 
}
