- (void)viewDidLoad

    - (IBAction)presentNewVC:(UIButton *)sender
    {
        SecondVC *vc = [[SecondVC alloc]init];
        //completion 参数是模态弹出完成时调用的block
        [self presentViewController:vc animated:YES completion:
         ^{
             vc.view.backgroundColor = [UIColor yellowColor];

        sender.frame = sender.frame = CGRectMake(26, 102, 268, 30);
        sender.backgroundColor = [UIColor blueColor];

             }
             else

                 NSLog(@"动画停止");
             }
         }];
        //停止动画
        [_animationButton.layer removeAllAnimations];
    }
    
    //排序
    - (IBAction)sortClick:(UIButton *)sender
    {
        [_array sortUsingComparator:^NSComparisonResult(id obj1, id obj2) {
            //比较数字
    //        if ([obj1 integerValue] < [obj2 integerValue])

    //        }
            //比较字符串
            return [obj1 compare:obj2 options:NSCaseInsensitiveSearch];
        }];
        NSLog(@"排序之后数组\n%@",_array);
    }
    
    //ASI请求
    - (IBAction)ASIRequestClick:(UIButton *)sender
    {
        __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:@"http://www.baidu.com"]];
        //设置请求完成时的block
        [request setCompletionBlock:^
        {
            NSLog(@"%@",request.responseString);
        }];
    
        //设置请求失败时调用的block
        //[request setFailedBlock:<#^(void)aFailedBlock#>];
        [request startAsynchronous];
    }

输出结果如下：
