常用框架集成方式：subModule、Carthage及CocoaPods

subModule：

基于Git管理、使用简单、功能较少，只能下载全部项目、debug方便

Carthage：

Swift语言、安装使用、去中心化管理，提供framework文件、debug不方便

CocoaPods：

基于Ruby、安装使用、去中心化管理，生成workspace、debug方便

CocoaPods

开源框架的使用（AFNetWroking）

·使用CocoaPods集成

/* Create a new file: podfile
target 'GSCApp1' do
	pod 'AFNetworking'
end
*/

// 安装 pod install
// 更新 pod update

·加载真实网络数据

// AFHTTPSessionManager
- (NSURLSessionDataTask *)GET:(NSString *)URLString
                   parameters:(nullable id)parameters
                      headers:(nullable NSDictionary <NSString *, NSString *> *)headers
                     progress:(nullable void (^)(NSProgress * _Nonnull))downloadProgress
                      success:(nullable void (^)(NSURLSessionDataTask * _Nonnull, id _Nullable))success
                      failure:(nullable void (^)(NSURLSessionDataTask * _Nullable, NSError * _Nonnull))failure
{
    
    NSURLSessionDataTask *dataTask = [self dataTaskWithHTTPMethod:@"GET"
                                                        URLString:URLString
                                                       parameters:parameters
                                                          headers:headers
                                                   uploadProgress:nil
                                                 downloadProgress:downloadProgress
                                                          success:success
                                                          failure:failure];
    
    [dataTask resume];
    
    return dataTask;
}

- (nullable NSURLSessionDataTask *)POST:(NSString *)URLString
                             parameters:(nullable id)parameters
                                headers:(nullable NSDictionary <NSString *, NSString *> *)headers
                               progress:(nullable void (^)(NSProgress *uploadProgress))uploadProgress
                                success:(nullable void (^)(NSURLSessionDataTask *task, id _Nullable responseObject))success
                                failure:(nullable void (^)(NSURLSessionDataTask * _Nullable task, NSError *error))failure
{
    NSURLSessionDataTask *dataTask = [self dataTaskWithHTTPMethod:@"POST" URLString:URLString parameters:parameters headers:headers uploadProgress:uploadProgress downloadProgress:nil success:success failure:failure];
    
    [dataTask resume];
    
    return dataTask;
}

二次封装&chromium

AFNetworking网络请求的简单使用

//
//  GSCListLoader.m
//  GSCApp1
//
//  Created by gsc on 2024/5/20.
//

#import "GSCListLoader.h"
#import "AFNetworking/AFNetworking.h"

@implementation GSCListLoader

-(void)loadListData{
    NSString *urlString        = @"http://v.juhe.cn/toutiao/index?type=top&key=97ad001bfcc2082e2eeaf798bad3d54e";
//    NSURL *listURL             = [NSURL URLWithString:urlString];
    
//    NSURLRequest *listRequest  = [NSURLRequest requestWithURL:listURL];
    
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    
    [manager GET:urlString parameters:nil headers:nil progress:^(NSProgress * _Nonnull downloadProgress) {
    
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    
    }];
    
//    NSURLSession *session      = [NSURLSession sharedSession];
//    
//    NSURLSessionTask *dataTask = [session dataTaskWithURL:listURL completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
//    }];
//    
//    [dataTask resume];
}

IOS中的JSON解析

JSON：轻量级，可读性高，纯文本形式的数据交互格式

基本数据格式：Number, Boolean, String, Null, Array, Object(Dictionary)

其他数据格式：protobuf（内容不具有可读性，但是高性能）

NSJSONSerialization：提供JSON数据和系统对象之间的转换

+ (nullable NSData *)dataWithJSONObject:(id)obj options:(NSJSONWritingOptions)opt error:(NSError **)error;

+ (nullable id)JSONObjectWithData:(NSData *)data options:(NSJSONReadingOptions)opt error:(NSError **)error;

// Options
typedef NS_OPTIONS(NSUInteger, NSJSONReadingOptions) {    // 是否可变类型数据&外层数据格式
    NSJSONReadingMutableContainers = (1UL << 0),
    NSJSONReadingMutableLeaves = (1UL << 1),
    NSJSONReadingFragmentsAllowed = (1UL << 2),

#if !0
    NSJSONReadingJSON5Allowed API_AVAILABLE(macos(12.0), ios(15.0), watchos(8.0), tvos(15.0)) = (1UL << 3),
#endif
    NSJSONReadingTopLevelDictionaryAssumed API_AVAILABLE(macos(12.0), ios(15.0), watchos(8.0), tvos(15.0)) = (1UL << 4),

    NSJSONReadingAllowFragments API_DEPRECATED_WITH_REPLACEMENT("NSJSONReadingFragmentsAllowed", macos(10.7, API_TO_BE_DEPRECATED), ios(5.0, API_TO_BE_DEPRECATED), watchos(2.0, API_TO_BE_DEPRECATED), tvos(9.0, API_TO_BE_DEPRECATED)) = NSJSONReadingFragmentsAllowed,
} API_AVAILABLE(macos(10.7), ios(5.0), watchos(2.0), tvos(9.0));

typedef NS_OPTIONS(NSUInteger, NSJSONWritingOptions) {    // 缩进 & 单行
    NSJSONWritingPrettyPrinted = (1UL << 0),

    /* Sorts dictionary keys for output using [NSLocale systemLocale]. Keys are compared using NSNumericSearch. The specific sorting method used is subject to change.
     */
    NSJSONWritingSortedKeys API_AVAILABLE(macos(10.13), ios(11.0), watchos(4.0), tvos(11.0)) = (1UL << 1),
    NSJSONWritingFragmentsAllowed = (1UL << 2),
    NSJSONWritingWithoutEscapingSlashes API_AVAILABLE(macos(10.15), ios(13.0), watchos(6.0), tvos(13.0)) = (1UL << 3),
} API_AVAILABLE(macos(10.7), ios(5.0), watchos(2.0), tvos(9.0));

使用结构化的数据进行解析和展示

读取JSON得到的数据属性：

//
//  GSCListItem.h
//  GSCApp1
//
//  Created by gsc on 2024/5/23.
//

#import <Foundation/Foundation.h>

NS_ASSUME_NONNULL_BEGIN


/*
 列表结构化属性
 */

@interface GSCListItem : NSObject

@property (nonatomic, copy, readwrite)  NSString * category;
//@property (nonatomic, copy, readwrite)  NSString * isContent;
@property (nonatomic, copy, readwrite)  NSString * picUrl;
@property (nonatomic, copy, readwrite)  NSString * uniquekey;
@property (nonatomic, copy, readwrite)  NSString * title;
@property (nonatomic, copy, readwrite)  NSString * date;
@property (nonatomic, copy, readwrite)  NSString * authorName;
@property (nonatomic, copy, readwrite)  NSString * articleUrl;

-(void) configWithDictionary:(NSDictionary *) dictionary;

@end

NS_ASSUME_NONNULL_END




//
//  GSCListItem.m
//  GSCApp1
//
//  Created by gsc on 2024/5/23.
//

#import "GSCListItem.h"

@implementation GSCListItem

- (void)configWithDictionary:(NSDictionary *)dictionary {
    self.category = [dictionary objectForKey:@"category"];
    self.picUrl = [dictionary objectForKey:@"thumbnail_pic_s"];
    self.uniquekey = [dictionary objectForKey:@"uniquekey"];
    self.title = [dictionary objectForKey:@"title"];
    self.date = [dictionary objectForKey:@"date"];
    self.authorName = [dictionary objectForKey:@"author_name"];
    self.articleUrl = [dictionary objectForKey:@"url"];
}

    NSURL *listURL             = [NSURL URLWithString:urlString];

        NSMutableArray *listItemArray = @[].mutableCopy;
        for (NSDictionary * info in dataArray){
            GSCListItem *listItem = [[GSCListItem alloc] init];
            [listItem configWithDictionary:info];
            [listItemArray addObject:listItem];
        }
        NSLog(@"");
    }];

    [dataTask resume];
