iOS NSURLConnection基础网络请求封装

现在NSURLConnection在开发中会使用的越来越少，iOS9已经将NSURLConnection废弃，现在最低版本一般适配iOS7，所以也可以使用。

用法：

FSKRequest *request = [[FSKRequest alloc]initWithUrl:@"http://www.cnblogs.com/kakaluote123/articles/5426923.html" withResponseBlock:^(BOOL isFinsh, id result, NSString *type) {        if (isFinsh == YES) {            NSLog(@"请求成功");        }else{            NSLog(@"请求失败");        }        NSLog(@"%@",type);        NSLog(@"%@",result);    }];

这里写图片描述
