使用未解決的標識符「requestIPViewController」，曖昧參考成員「下標」

Question

的它讓我有對碼

那麼，如何解決這個問題的一些問題？

self.presentViewController[requestIPViewController, animated:YES, completion:nil]; 

} 
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) { 
    let image = info[UIImagePickerControllerOriginalImage] as UIImage 

Answer 1

如果是在SWIFT 2.3，那麼它應該是這樣的

self.presentViewController(imagePicker, animated: true, completion: nil) 

而且你必須鍵入投它喜歡它

let image = info[UIImagePickerControllerOriginalImage] 
      as! UIImage 

和SWIFT 3.0，它看起來像

self.present(imagePicker, animated: true, completion: nil) 

和detegate方法看起來像tha t

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { 

    let mediaType = info[UIImagePickerControllerMediaType] as! NSString 

    self.dismiss(animated: true, completion: nil) 

    if mediaType.isEqual(to: kUTTypeImage as String) { 
     let image = info[UIImagePickerControllerOriginalImage] 
      as! UIImage 
    } 
} 

希望它有幫助。
