2 带有 3 个按钮的 UIAlertView? [英] 2 UIAlertView with 3 buttons?

问题描述

我想知道如何制作 2 个带有 3 个按钮的 UIAlertView，UIAlertViews(2) 需要不同，选项和操作...如何???

I wanna know how can I make 2 UIAlertView, with 3 buttons, the UIAlertViews(2) needs be different, the options and the actions... how ???

推荐答案

试试这个:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Welcome" message:@"Message." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:@"Button 2", @"Button 3", nil];
alert.tag = 1;               
[alert show];

然后对下一个alertView做同样的事情，只需将标签更改为2

then do the same for the next alertView, just change the tag to 2

然后运行这个方法

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
     if(alert.tag == 1) {
          //the alert tag 1 was just closed - do something
     }
}

另外 - 确保包含 UIAlertViewDelegate
