推荐答案

如果您在> iOS 4.0（对于块）并且您只需要一个或两个按钮，则可以使用此类别：

If you are on > iOS 4.0 (for blocks) and you only want one or two buttons, you could use this category I made:

它绕过了添加用户信息的需要，因为您将点击handeling功能直接放入警报中。例如

It bypasses the need to add user info since you put your click handeling function straight into the alert. e.g.

 #import UIAlertView+Blocks.h

 ...

 ...

 NSString* myUserInfo = @"example";

 [UIAlertView displayAlertWithTitle:@"Example Alert View With Blocks"
                            message:nil
                    leftButtonTitle:@"Ok"
                  leftButtonAction:^{
                                      NSLog(@"%@", myUserInfo);
                                    } 
                  rightButtonTitle:nil
                 rightButtonAction:nil];
