ios - 如何告诉我的 imagePickerController 委托(delegate)我的自定义 UIButton 正在处理拍照

Question

如何指示 imagepickercontroller 委托(delegate)允许我的自定义 UIButton 拍照，然后将其存储在 didFinishPickingImage 委托(delegate)方法中的 imageView 文件中？非常感谢您的帮助。

 @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)
}

您需要实现 didFinishPickingMediaWithInfo:委托(delegate)。当您使用自定义捕获按钮拍照时，将调用此委托(delegate)方法。

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