IOS UIAlertView

UIAlertView *alertView = [[UIAlertViewalloc] initWithTitle:@"title"message:@""delegate:selfcancelButtonTitle:@"cancel"otherButtonTitles:@"other",nil];

[alertView show];

用到代理方法時要添加協定

#pragma mark - UIAlertView Delegate

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

{

   NSLog(@"index %d",buttonIndex);

}
