一旦AFN有較大的變動(dòng)，用到AFN的項(xiàng)目需要更改很多的地方，為了避免這種情況，一般會(huì)對(duì)AFN封裝出一個(gè)類忆植，這樣有了變動(dòng)之后，只需要更改這個(gè)類即可（代碼如下）
.h文件
#import <Foundation/Foundation.h>
typedef NS_ENUM(NSInteger, RequestMethod)
{
post,
get
};
@interface NetworkTools : NSObject
+ (instancetype)shareNetworkTools;
/**
* requestMethod:請(qǐng)求方式
* urlString:請(qǐng)求地址
* parameters:請(qǐng)求參數(shù)
* responseBlock:請(qǐng)求成功或失敗的回調(diào)

AFN與其它框架對(duì)比
AFNetWorking:簡(jiǎn)單易用,提供了基本夠用的常用功能,有人更新和維護(hù)谒臼，而且目前使用者很多 朝刊。其相關(guān)資料，文檔蜈缤，demo很多拾氓，很好找遇到問(wèn)題好解決。
ASIHttpRequest: ASI的底層基于純C語(yǔ)言的CFNetwork框架,功能很強(qiáng)大,可惜作者已停止更新.
MKNetWorkKit:簡(jiǎn)單易用,維護(hù)和使用者少.
