本文介绍了一个使用AFNetworking发起网络请求的Objective-C示例。该示例展示了如何配置HTTP会话管理器，设置请求超时，并通过GET请求获取数据。同时，文章还详细解释了如何解析返回的JSON数据并将其转换为模型对象。

#import <AFNetworking/AFNetworking.h>

@interface CZNetworkTools :AFHTTPSessionManager

+ (instancetype)sharedTools;

@end

=========================

#import "CZNetworkTools.h"

@implementation CZNetworkTools

+ (instancetype)sharedTools {

staticCZNetworkTools *tools;

static dispatch_once_t onceToken;

dispatch_once(&onceToken, ^{

NSURL *baseURL = [NSURLURLWithString:@"http://c.m.163.com/nc/"];

NSURLSessionConfiguration *config = [NSURLSessionConfigurationdefaultSessionConfiguration];

//设置请求的超时时长

config.timeoutIntervalForRequest =15;

tools = [[self alloc] initWithBaseURL:baseURL sessionConfiguration:config];

//acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", nil];

tools.responseSerializer.acceptableContentTypes = [NSSetsetWithObjects:@"application/json",@"text/json", @"text/javascript",@"text/html",nil];

});

return tools;

}

@end

========================

#import "CZHeadline.h"

#import "CZNetworkTools.h"

@implementation CZHeadline

+ (instancetype)headlineWithDic:(NSDictionary *)dic {

CZHeadline *headline = [[selfalloc] init];

[headline setValuesForKeysWithDictionary:dic];

return headline;

}

- (void)setValue:(id)value forUndefinedKey:(NSString *)key {}

//发送异步请求,字典转模型

+ (void)headlinesWithSuccess:(void(^)(NSArray *array))successBlock errorBlock:(void(^)(NSError *e))errorBlock {

//发送异步请求,获取json数据

[[CZNetworkTools sharedTools] GET:@"ad/headline/0-4.html"parameters:nilprogress:nilsuccess:^(NSURLSessionDataTask *_Nonnull task, NSDictionary *_Nullable responseObject) {

//获取json数据,解析json

//假设rootkey是变化的,获取rootkey

NSString *rootkey = responseObject.keyEnumerator.nextObject;

//获取数组--存储的都是字典

NSArray *array = responseObject[rootkey];

//存储对象的数组

NSMutableArray *mArray = [NSMutableArrayarrayWithCapacity:10];

for (NSDictionary *dicin array) {

//字典转模型

CZHeadline *headline = [selfheadlineWithDic:dic];

[mArray addObject:headline];

}

//调用block

if (successBlock) {

successBlock(mArray.copy);

}

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

if (errorBlock) {

errorBlock(error);

}

}];

}

@end
