本文介绍了一种iOS应用中使用的网络请求封装方法，利用AFHTTPSessionManager进行网络请求的处理，并通过实例展示了登录功能的具体实现。

有几天没有写博客了，今天想写一下网络请求的一点封装，从同事那里看到的，不错的封装吧，不过后半段是我自己的风格；

首先：创建和初始化manager

#import <Foundation/Foundation.h>

#import "GTMObjectSingleton.h"

@interface JXPostManage : NSObject

@property (nonatomic, retain)AFHTTPSessionManager *manager;

-(void)postWithPath:(NSString *)path

params:(NSDictionary *)params

vc:(UIViewController *)vc

success:(void (^)(NSURLSessionTask *task, id responseObject))success

failure:(void (^)(NSURLSessionTask *task, id responseObject))failure;

@end

然后在.m中：

#import "JXPostManage.h"

#import "AppDelegate.h"

#import "ProgressHUD.h"

@implementation JXPostManage

-(id)init

{

self = [super init];

if (self) {

_manager = [AFHTTPSessionManager manager];

}

return self;

}

-(void)postWithPath:(NSString *)path

params:(NSDictionary *)params

vc:(UIViewController *)vc//VC 为show-->视图赋值为--->self

success:(void (^)(NSURLSessionTask *task, id responseObject))success

failure:(void (^)(NSURLSessionTask *task, id responseObject))failure

{

NSLog(@"URL -- %@%@",NetPerfix,path);

NSLog(@"请求参数:%@",params);

if (vc != nil) {

[SVProgressHUD showWithStatus:@"载入中..."];

}

NSString *url=[NSString stringWithFormat:@"%@%@",NetPerfix,path];

NSLog(@"请求url......%@",url);

[_manager POST:url

parameters:params

progress:nil

success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {

NSLog(@"errorMessage---%@",responseObject[@"msg"]);

NSLog(@"Path---%@",path);

// if (responseObject[@"resultscode"]) {

// if ([responseObject[@"resultscode"] intValue] == 1) {

// NSLog(@"2");

// success(task,responseObject);

// }else {

// if ([responseObject[@"resultscode"] intValue] == 0) {

// NSLog(@"3");

// }else {

// NSLog(@"4");

// NSDictionary *userInfo = [NSDictionary dictionaryWithObjectsAndKeys:

// responseObject[@"errorMessage"], NSLocalizedDescriptionKey, nil];

// NSError *error = [NSError errorWithDomain:@"FSB" code:502 userInfo:userInfo];

// failure(task,error);

// }

// }else {

// NSLog(@"5");

// NSDictionary *userInfo = [NSDictionary dictionaryWithObjectsAndKeys:

// @"服务器数据出错", NSLocalizedDescriptionKey, nil];

// NSError *error = [NSError errorWithDomain:@"FSB" code:503 userInfo:userInfo];

// failure(task,error);

// }

if ([responseObject[@"resultscode"] intValue] == 2) {

[self isChenckOutWithVC:vc];

[SVProgressHUD dismiss];

return ;

}else{

if ([responseObject[@"resultscode"] intValue] == 1) {

[SVProgressHUD dismiss];

success(task,responseObject);

return ;

}else if([responseObject[@"resultscode"] intValue] == 0){

[self showErrorWithVC:vc withMessag:[NSString stringWithFormat:@"%@",responseObject[@"errorMessage"]]];

[SVProgressHUD dismiss];

return ;

}

if (vc != nil)

{

[SVProgressHUD dismiss];

}

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

NSLog(@"error -- %@",[error localizedDescription]);

if (vc != nil) {

[SVProgressHUD dismiss];

[vc showToast:[error localizedDescription]];

}

failure(task,error);

}];

}

- (void)isChenckOutWithVC:(UIViewController *)vc{

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"账号信息已过期或者不存在，请重新登录" preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *action1 = [UIAlertAction actionWithTitle:@"确认" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

[[NSUserDefaults standardUserDefaults] removeObjectForKey:USER_ID_Key];

[[NSUserDefaults standardUserDefaults] removeObjectForKey:@"islogin"];

[[NSUserDefaults standardUserDefaults] removeObjectForKey:USER_TOKEN_KEY];

[[NSUserDefaults standardUserDefaults] removeObjectForKey:@"pwd"];

[[NSUserDefaults standardUserDefaults] removeObjectForKey:USER_PWD];

[[NSUserDefaults standardUserDefaults] removeObjectForKey:@"phone"];

[[NSUserDefaults standardUserDefaults] synchronize];

AppDelegate * app = (AppDelegate *)[UIApplication sharedApplication].delegate;

// [app setLoginRootViewController];

}];

[alert addAction:action1];

[vc presentViewController:alert animated:YES completion:nil];

}

- (void)showErrorWithVC:(UIViewController *)vc withMessag:(NSString *)msg{

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:msg preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *action0 = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil];

[alert addAction:action0];

[vc presentViewController:alert animated:YES completion:nil];

}

@end

然后继承与上面的文件

#import "JXPostManage.h"

@interface ZNBNetManager : JXPostManage

+( instancetype ) sharedSingleton;

+(id) allocWithZone:(struct _NSZone *)zone ;

-(id) copyWithZone:(struct _NSZone *)zone ;

//TODO:登录

- (void)vipUserInterWithFlag:(NSString *)flag

type:(NSString *)type

username:(NSString *)username

passwd:(NSString *)passwd

deviceid:(NSString *)deviceid

channelid:(NSString *)channelid

osType:(NSString *)osType

vc:(UIViewController *)vc//VC 为show-->视图赋值为--->self

success:(void (^)(NSURLSessionTask *task, id responseObject))success

failure:(void (^)(NSURLSessionTask *task, id error))failure;

@end

#import "ZNBNetManager.h"

@implementation ZNBNetManager

static ZNBNetManager *shareSingleton = nil;

+( instancetype ) sharedSingleton {

static dispatch_once_t onceToken;

dispatch_once ( &onceToken, ^ {

shareSingleton = [[super allocWithZone:NULL] init] ;

} );

return shareSingleton;

}

+(id) allocWithZone:(struct _NSZone *)zone {

return [ZNBNetManager sharedSingleton] ;

}

-(id) copyWithZone:(struct _NSZone *)zone {

return [ZNBNetManager sharedSingleton] ;

}

//TODO:登录

- (void)vipUserInterWithFlag:(NSString *)flag

type:(NSString *)type

username:(NSString *)username

passwd:(NSString *)passwd

deviceid:(NSString *)deviceid

channelid:(NSString *)channelid

osType:(NSString *)osType

vc:(UIViewController *)vc//VC 为show-->视图赋值为--->self

success:(void (^)(NSURLSessionTask *task, id responseObject))success

failure:(void (^)(NSURLSessionTask *task, id error))failure{

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:

flag,@"flag",

type,@"type",

username,@"username",

passwd,@"passwd",

deviceid,@"deviceid",

channelid,@"channelid",

osType,@"osType",

nil];

[self postWithPath:@"VipUserInter" params:params vc:vc success:success failure:failure];

}

@end

规范性的网络请求可以高效迅速，减少错误，这是json的请求封装，对于xml我自己封装了一个，基于系统的，以后贴出来：
