如何告訴我的imagePickerController委託我的自定義UIButton正在處理圖片的拍攝

Question

如何獲取指示imagepickercontroller委託以允許我的自定義UIButton拍攝照片，然後將其存儲在didFinishPickingImage委託的imageView文件中方法？？幫助將不勝感激。

@IBAction func takePicture(sender: AnyObject) { 
    imagePicker.takePicture() 
} 

override func viewDidAppear(animated: Bool) { 
    overlayView.opaque = true 
    overlayView.backgroundColor = UIColor.clearColor() 

    imagePicker.sourceType = UIImagePickerControllerSourceType.Camera 
    imagePicker.delegate = self 
    imagePicker.showsCameraControls = false 
    imagePicker.allowsEditing = true 
    imagePicker.cameraOverlayView = overlayView 

    self.presentViewController(imagePicker, animated: false, completion: nil) 
} 

Answer 1

您需要實施didFinishPickingMediaWithInfo:委託。當您使用自定義捕捉按鈕拍攝照片時，將調用此委託方法。

func imagePickerController(_ picker: UIImagePickerController, 
     didFinishPickingMediaWithInfo info: [String : AnyObject]) 
{ 
    let image: UIImage = info[UIImagePickerControllerOriginalImage] as! UIImage; 
    yourImageView.image = image; 
}

不可能通過imagepickercontroller的委託。你必須按原樣使用它。如果你想讓你的自定義按鈕做一些事情 - 不幸的是你必須編寫你自己的imagepickercontroller。
