你可以调用下面解释的UIAlertView的委托方法......

 - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
 {
      if (buttonIndex == 0) {
          //Your Code   //For First Button
      } else if (buttonIndex == 1) {
          //Your Code   //For Second Button
      }
 }

试试这个： -

UIAlertView *alertView;  
alertView = [[UIAlertView alloc] initWithTitle:@"Peer Disconnected!" message:nil delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:@"Continue", nil];
[alertView show];
[alertView release];


- (void)alertView:(UIAlertView *)alert didDismissWithButtonIndex:(NSInteger)buttonIndex
{   
    if(buttonIndex==0)
    {
NSLog(@"cancel clicked");
    }
    else if(buttonIndex==1)
    {
NSLog(@"continue clicked");
    }
    }

Answer 3

UIAlertView *alertView;  
alertView = [[UIAlertView alloc] initWithTitle:@"Peer Disconnected!" message:nil delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Continue", nil];
[alertView show];
[alertView release];

实施此委托方法。

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if(buttonIndex == alertView.cancelButtonIndex) {
// Cancel operation...
}else if (buttonIndex == alertView.firstOtherButtonIndex) {
// Continue operation...
}
}
