我有一台服务器,我得到了响应:
{"products": [

"name": "zzzz®",
"sort_order": 0,
"brand": "zzzas",

我正在使用该代码来解析 JSON
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"link"]]; AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSDictionary *jsonDict = (NSDictionary *) JSON;
NSArray *products = [jsonDict objectForKey:@"products"];
[products enumerateObjectsUsingBlock:^(id obj,NSUInteger idx, BOOL *stop){
NSString *productIconUrl = [obj objectForKey:@"icon_url"];
}];
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) { NSLog(@"Request Failure Because %@",[error userInfo]); }];
[operation start];
如何获取所有 icon_url 并将它们分配到 AFnetworking 队列以进行序列化下载。响应中的某些文件也是 pdf 或 mp4 文件,因此我希望所有这些文件作为请求打包在一个数组中,并一个一个地下载它们。
我搜索了 AFClient,但可以找到任何源代码或示例用法。
