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];
