本文介绍了一个简单的iOS应用程序如何使用AFNetworking库进行网络请求的过程。包括配置允许任意加载、导入AFNetworking、创建数据模型、实现GET和POST请求以及监听网络状态等步骤。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

一 , 打开网络请求
info.plist
App Transport Security Settings
Allow Arbitrary Loads
二 , 倒入AFNetworking第三方
三 , 创建Model类继承于nsobject
Model内 .h代码为

#import <Foundation/Foundation.h>

@interface MyModel : NSObject
@property(nonatomic,strong) NSString * categoryId,*categoryName,*count,*lessenPrice;
@end

NSString为接口内的名称
四 , 拖拽Main.storyboard基本为:
然后添加到ViewController.m
这里写图片描述
五 , ViewController.m内代码为

#import "ViewController.h"
#import "AFNetworking.h"
#import "MyModel.h"
//宏
#define JSON_URL @"http://iappfree.candou.com:8080/free/categories/free"
#define PATH @"http://api.izhangchu.com"    // methodName: HomeIndex
@interface ViewController ()<UITableViewDelegate , UITableViewDataSource>
@property (weak, nonatomic) IBOutlet UITableView *tableView;
    @property (nonatomic , strong)NSMutableArray *dataSoure;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.tableView.delegate = self;
    self.tableView.dataSource = self;
    self.dataSoure = [NSMutableArray new];
}
- (IBAction)GET:(id)sender {
    //创建数据请求管理对象
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    //这是关闭它的自动解析功能
    //mannage.responseSerializer = [AFHTTPResponseSerializer serializer];
    //添加的支持的解析类型@"text/html",
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/json"];
    //GET 接口
    [manager GET:JSON_URL parameters:nil headers:nil progress:^(NSProgress * _Nonnull downloadProgress) {

    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        //数据请求的成功回调
        NSLog(@"//////////%@",responseObject);

        for (NSDictionary *dic in responseObject[@"category"]) {
            MyModel *model = [MyModel new];
            [model setValuesForKeysWithDictionary:dic];
            [self.dataSoure addObject:model];
        }
        //重要的一点   主线程
        dispatch_async(dispatch_get_main_queue(), ^{
            [self.tableView reloadData];
        });

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        //数据请求失败的回调
        NSLog(@"//////////%@",error);
    }];
}
- (IBAction)POST:(id)sender {
    //
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    //拼接参数
    NSDictionary *dic = @{@"methodName":@"Homeindex"};

    [manager POST:PATH parameters:dic headers:nil progress:^(NSProgress * _Nonnull uploadProgress) {

    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSLog(@"%@",responseObject);

        for (NSDictionary *dic in responseObject[@"category"]) {
            MyModel *model = [MyModel new];
            [model setValuesForKeysWithDictionary:dic];
            [self.dataSoure addObject:model];
        }
        //重要的一点   主线程
        dispatch_async(dispatch_get_main_queue(), ^{
            [self.tableView reloadData];
        });
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"%@",error);
    }];
}
- (IBAction)Moniter:(id)sender {
    //做一个网络状态监听
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
        /*
         AFNetworkReachabilityStatusUnknown          = -1,
         AFNetworkReachabilityStatusNotReachable     = 0,
         AFNetworkReachabilityStatusReachableViaWWAN = 1,
         AFNetworkReachabilityStatusReachableViaWiFi = 2,
         */
        NSLog(@"%ld",(long)status);
    }];
    //开始监听
    [manager.reachabilityManager startMonitoring];
    //停止监听

}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return self.dataSoure.count;
