拿走即用之afn封裝（OC版）
afn封裝
一旦AFN有較大的變動，用到AFN的項目需要更改很多的地方，為了避免這種情況，一般會對AFN封裝出一個類，這樣有了變動之后，只需要更改這個類即可（代碼如下）
.h文件
#import <Foundation/Foundation.h>
typedef NS_ENUM(NSInteger, RequestMethod)
{
post,
get
};
@interface NetworkTools : NSObject
- (instancetype)shareNetworkTools;
/**
- requestMethod:請求方式
- urlString:請求地址
- parameters:請求參數
- responseBlock:請求成功或失敗的回調
*/
- (void)requestWithMethod:(RequestMethod)requestMethod andUrlString:(NSString )urlString andParameters:(id) parameters andFinished:(void(^)(id response, NSError error))responseBlock;
/**
- data:上傳資料
- name:上傳資料的名字
- urlString:請求地址
- parameters:請求參數
- responseBlock:請求成功或失敗的回調
*/
- (void)requestWithData:(NSData )data andName:(NSString )name andUrlString:(NSString )urlString andParameters:(id) parameters andFinished:(void(^)(id response, NSError error))responseBlock;
