UIAlertView已弃用。您现在可以使用UIAlertController，如此处所述。

1. 您可以像这样创建UIAlertView

1. You can create a UIAlertView like this

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Really reset?" 
                          message:@"Do you really want to reset this game?" 
                          delegate:self 
                          cancelButtonTitle:@"Cancel" 
                          otherButtonTitles:@"reset", nil];

[alert show];

要处理AlertView按钮点击，您必须
符合 UIAlertViewDelegate 协议。

@interface YourViewController:UIViewController<UIAlertViewDelegate>{
  .......
  .......
}

> UIAlertViewDelegate 协议方法

- (void)alertView:(UIAlertView *)alertView 
                   clickedButtonAtIndex:(NSInteger)buttonIndex{
    if (buttonIndex == [alertView cancelButtonIndex]){
      //cancel clicked ...do your action
    }else{
      //reset clicked
    }
}
