在UIAlertController中将图像添加到UIAlertAction [英] Add Image to UIAlertAction in UIAlertController

问题描述

我看过UIAlertControllers的几个屏幕截图，行左边有一个图像，但我没有在文档中看到它。视觉示例是
以下是我现在为我的控制器提供的代码：

I have seen a couple screen shots of a UIAlertControllers with an image on the left of the row but I do not seen it in the documentation. An example visual is Here is the code that I have for my controller right now:

UIAlertController * view =   [UIAlertController
                                 alertControllerWithTitle:@"My Title"
                                 message:@"Select you Choice"
                                 preferredStyle:UIAlertControllerStyleActionSheet];
    UIAlertAction* ok = [UIAlertAction
                         actionWithTitle:@"OK"
                         style:UIAlertActionStyleDefault
                         handler:^(UIAlertAction * action)
                         {
                          }];
    [view addAction:ok];
    [self presentViewController:view animated:YES completion:nil];

推荐答案

这就是它的完成方式：

let image = UIImage(named: "myImage")
var action = UIAlertAction(title: "title", style: .default, handler: nil)
action.setValue(image, forKey: "image")
alert.addAction(action)

图片属性未公开，因此无法保证在将来的版本中有效，但现在工作正常

the image property is not exposed, so there's no guarantee of this working in future releases, but works fine as of now
