Question

我只需要显示DELETE和CANCEL按钮作为警报，没有警报标题或消息，并向DELETE按钮添加操作。试图修改以下代码但无法成功。另外，当显示DELETE和CANCEL按钮时，我想让UIVIEW变暗。这样做的最佳方式是什么？

 let refreshAlert = UIAlertController(title: "Alert", message: "Are you sure ?", preferredStyle: UIAlertControllerStyle.Alert)

    var imageView = UIImageView(frame: CGRectMake(220, 10, 40, 40))
    let yourImage = UIImage(named: "delete")
    imageView.image = yourImage

    refreshAlert.view.addSubview(imageView)

    refreshAlert.addAction(UIAlertAction(title: "Ok", style: .Default, handler: { (action: UIAlertAction!) in ...

Answer 1

此代码有助于：

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

有些表情符号有图像，你可以使用它们，如果你的图像有标准的表情符号，这对你有帮助。请在示例中检查LOCK表情符号，＆gt;

UIAlertAction* HDQuality = [UIAlertAction
                                actionWithTitle:@" lockk Action"
                                style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction * action)
                                {
                                    [alert dismissViewControllerAnimated:YES completion:nil];



                                }];

[alert addAction:HDQuality];
