方法1、直接生成无按钮的UIAlertView

        UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(7, 19, 270, 30)];

       label.text = @"我是一个无按钮的UIAlertView";
       label.textAlignment = UITextAlignmentCenter;
       label.textColor = [UIColor whiteColor];
       label.backgroundColor = [UIColor clearColor];

       UIAlertView *alert = [[UIAlertView alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
       [alert addSubview:label];

       [alert show];

      self.globalAlertView = alert; //将UIAlertView实例赋值给全局变量
       //3秒钟后自动消失
       [self performSelector:@selector(autoDismissWithShareLocation) withObject:nil afterDelay:3.0f];

- (void)autoDismissWithShareLocation{
[self.globalAlertView dismissWithClickedButtonIndex:0 animated:YES];

}

方法2、通过实现UIAlertViewDelegate代理方法实现

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[Common getTextByTag:@"updateError"]
                                                                message:nil
                                                               delegate:self
                                                      cancelButtonTitle:[Common getTextByTag:@"confirm"]
                                                      otherButtonTitles:nil];

alert.delegate = self;
[alert show];
[alert release];

-(void)willPresentAlertView:(UIAlertView *)alertView{

    for (UIView* view in [alertView subviews])
    {
        //把UIAlertView中的按钮删除
        if ([[[view class] description] isEqualToString:@"UIAlertButton"]
            || [[[view class] description] isEqualToString:@"UIThreePartButton"])
        {
            [view removeFromSuperview];
        }
    }

}
