UIActionSheet with 2 buttons .... {iPhone SDK}

Question

嗨iam用2个按钮创建UIActionSheet。现在我想要两个按钮做单独的工作。 我怎么可以声明对我的2个按钮：

- (void)actionSheet:(UIActionSheet *)menu 
       didDismissWithButtonIndex:(NSInteger)buttonIndex 

我用这个代码：

if (buttonIndex != [menu cancelButtonIndex]) { 
    // do somthing 
} 

但如果用户单击除取消按钮做财产以后任何按钮，这意味着什么。 谢谢。

Answer 1

- (void)actionSheet:(UIActionSheet *)menu didDismissWithButtonIndex:(NSInteger)buttonIndex { 
    if (buttonIndex == [menu cancelButtonIndex]) { 
     // do something because the user clicked "cancel". 
    } else { 
     // do something because the user clicked "the other button". 
    } 
} 

Answer 2

这将工作得更加普遍。你可以把它扩展到尽可能多的按钮，只要你喜欢：

- (void)actionSheet:(UIActionSheet *)menu didDismissWithButtonIndex:(NSInteger)buttonIndex { 

    switch (buttonIndex) { 
     case 0: 
      //do something 
      break; 
     case 1: 
      //do something else 
      break; 
     default: 
      break; 
    } 
} 

Answer 3

- (void)actionSheet:(UIActionSheet *)menu didDismissWithButtonIndex:(NSInteger)buttonIndex { 

    switch (buttonIndex) { 

     case 0: 

UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Title" 
message:@"hooo" 
delegate:self 
cancelButtonTitle:@"boo" 
otherButtonTitles:@"yoo"]; 

      [alert show]; 
      [alert release]; 

      break; 
      case 1: 
      self.view.backgroundColor = [UIColor redColor]; 
       break; 

     default: 
      break; 
    } 
}
