一：封装的好处

1.1 可以降低网络请求方法与Controller(控制器)的耦合度,即使网络使用的第三方框架发生不兼容、错误等问题从而想换框架时，也不用到每个控制器里面改代码(50、60页面会改到想哭)。 1.2 建立独立的工具类，方便管理。 1.3 优化代码结构。

二：导入AFNetworking

导入AFNetworking有两种方法：一种直接将AFNetworking文件拖入项目；另一种使用CocoaPods导入。

三：创建封装类

创建FBYHomeService类继承NSObject .h代码

//
//  FBYHomeService.h
//  agreePay
//
//  Created by fbyon 2017/4/24.
//  Copyright © 2017年 agreePay. All rights reserved.
//#import <Foundation/Foundation.h>@interface FBYHomeService : NSObject//pageNum和action标记参数，可以区分接口类型等
//Alldic为网络请求报文
//url接口地址
//success获取接口成功返回参数
//failure网络请求失败错误信息
- (void)searchMessage:(NSString *)pageNum andWithAction:(NSString *)action andWithDic:(NSDictionary *)Alldic andUrl:(NSString *)url andSuccess:(void(^)(NSDictionary *dic))success andFailure:(void(^)(int fail))failure;@end

.m代码

//
//  FBYHomeService.m
//  agreePay
//
//  Created by 范保莹 on 2017/4/24.
//  Copyright © 2017年 agreePay. All rights reserved.
//#import "FBYHomeService.h"#import "AFNetworking.h"@implementation FBYHomeService
- (void)searchMessage:(NSString *)pageNum andWithAction:(NSString *)action andWithDic:(NSDictionary *)Alldic andUrl:(NSString *)url andSuccess:(void (^)(NSDictionary *))success andFailure:(void (^)(int))failure{
   
   //1.创建ADHTTPSESSIONMANGER对象
   AFHTTPSessionManager *manager=[AFHTTPSessionManager manager];
   //2.设置该对象返回类型
   [manager.requestSerializer setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
   
if ([pageNum isEqualToString:[NSString stringWithFormat:@"get"]]) {
       
       NSString *urlstr= [NSString stringWithFormat:@"%@%@",AGREEHanBingURL,url];
       
       NSLog(@"%@",urlstr);
       //调出请求头
       manager.requestSerializer = [AFJSONRequestSerializer serializer];
       //将token封装入请求头
       
       NSUserDefaults *tokenid = [NSUserDefaults standardUserDefaults];
       NSString *token = [tokenid objectForKey:@"tokenid"];
       NSLog(@"%@",token);
       
       [manager.requestSerializer setValue:token forHTTPHeaderField:@"token"];
       
       [manager GET:urlstr parameters:nil progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
           NSDictionary *dic = responseObject;
           success(dic);
       } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
           
       }];
       
   }else {
           NSString *urlstr= [NSString stringWithFormat:@"%@%@",AGREENewFuWuURL,url];
           NSLog(@"%@",urlstr);
           [manager.requestSerializer setValue:@"1" forHTTPHeaderField:@"x-signature"];
           [manager.requestSerializer setValue:@"2" forHTTPHeaderField:@"x-timestamp"];
           manager.requestSerializer = [AFJSONRequestSerializer serializer];
           manager.responseSerializer = [AFJSONResponseSerializer serializer];
           [manager POST:urlstr parameters:Alldic progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
           
                 NSDictionary *dic = responseObject;
           
                 success(dic);
           
             }failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                 failure(404);
             }];  
   }
}@end

四：封装类的使用

LoginViewController.m中代码首先引入头文件

#import "AFNetworking.h"
#import "FBYHomeService.h"

使用代码

NSMutableDictionary *mutdic=[NSMutableDictionary dictionaryWithCapacity:0];
   
   mutdic[@"userName"] = @"admin";
   mutdic[@"password"] = @"admin";
   
   //网络请求
   FBYHomeService *service1 = [[FBYHomeService alloc]init];
   
   [service1 searchMessage:@"post" andWithAction:nil andWithDic:mutdic andUrl:MerchantLogin andSuccess:^(NSDictionary *dic) {
       
       NSLog(@"%@",dic);
       
       NSString *str = [dic objectForKey:@"code"];
       int intString = [str intValue];
       
       if (intString == 0) {
           
           NSString *token = [dic objectForKey:@"token"];
           
           NSLog(@"%@",token);
           NSUserDefaults *tokenid = [NSUserDefaults standardUserDefaults];
           [tokenid setObject:token forKey:@"tokenid"];
           [tokenid synchronize];
         
       }else{           UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:[dic objectForKey:@"msg"] preferredStyle:UIAlertControllerStyleAlert];
           
           UIAlertAction *action1 = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
               
           }];
           [alert addAction:action1];
           [self presentViewController:alert animated:YES completion:nil];
           
       }
       
   } andFailure:^(int fail) {
       
   }];
