Question

我希望UIAlertController在UIImageView中显示ActionSheet的提醒。但是当我运行应用程序时，它正在终止。

这是我的代码：

UIAlertController *alert = [UIAlertController
                                  alertControllerWithTitle:@"Title"
                                  message:@"Welcome"
                                  preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *okButton = [UIAlertAction
                            actionWithTitle:OK
                            style:UIAlertActionStyleDefault
                            handler:^(UIAlertAction *action)
                            {
                            }];
[alert addAction:okButton];
UIImageView *imgv = [[UIImageView alloc]initWithFrame:CGRectMake(20,20,50,50)];
imgv.image = [UIImage imageNamed:@"kaga.jpg"];
[alert setValue:imgv forKey:@"image"];
[self presentViewController:alert animated:YES completion:nil];

根据Apple Doc。

，无法将图像添加到UIAlertController

如果您愿意，可以创建自己的自定义视图，如：

如果您想在button上显示图片然后尝试这样：

UIAlertController * alert=   [UIAlertController
                                  alertControllerWithTitle:@"Title"
                                  message:@"Welcome"
                                  preferredStyle:UIAlertControllerStyleActionSheet];

    UIAlertAction* okButton = [UIAlertAction
                                actionWithTitle:OK
                                style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction * action)
                                {
//Do some thing here
                         [alert dismissViewControllerAnimated:YES completion:nil];

                                }];

[okButton setValue:[[UIImage imageNamed:@"kaga.jpg"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] forKey:@"image"];

[alert addAction:okButton];
[self presentViewController:alert animated:YES completion:nil];

更改此内容：

UIImageView *imgv=[[UIImageView alloc]initWithFrame:CGRectMake(20,20,50,50)];
    imgv.image=[UIImage imageNamed:@"kaga.jpg"];
    [alert setValue:imgv  forKey:@"image"];

对此：

UIImage *img= [UIImage imageNamed:@"kaga.jpg"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    [alert setValue:img  forKey:@"image"];
