AFNetworking的使用
1，下载AFNetworking 库https://github.com/AFNetworking/AFNetworking
2，解压把下面的文件导入工程里面
3,在需要用到的地方倒入文件头#import “AFNetworking.h”
4，建一个管理它的类
.h文件
@interface MyAFNetworking : NSObject
@property (assign,nonatomic,readonly) AFNetworkReachabilityStatus reachAbility;
+(MyAFNetworking *)getNetWorkingUtil;
//session作为请求头的post请求(有网络请求错误提示)
-(void)sessionRequestPostMethodHeader:(NSString )header port:(NSString )port parameters:(NSDictionary *)parameters result:(void (^)(NSDictionary *reobject,NSInteger errcode,NSString *msg)) result;
//session作为请求头的GET请求
-(void)sessionRequestGetMethodHeader:(NSString )header port:(NSString )port parameters:(NSDictionary *)parameters result:(void (^)(NSDictionary *reobject,NSInteger errcode,NSString *msg)) result;
.m文件
@interface MyAFNetworking ()

}
