Question

我有一个问题。我必须解析这个json：

{
        "category_id" = 1;
        fullname = "Wiadomo\U015bci";
        name = wiadomosci;
        "page_index" = 0;
        "show_live" = 1;
    },
        {
        "category_id" = 2;
        fullname = Kultura;
        name = kultura;
        "page_index" = 1;
        "show_live" = 0;
    },
        {
        "category_id" = 3;
        fullname = Rozrywka;
        name = rozrywka;
        "page_index" = 2;
        "show_live" = 0;
    },
        {
        "category_id" = 4;
        fullname = Biznes;
        name = biznes;
        "page_index" = 3;
        "show_live" = 0;
    }

我有两个数组，包含category_id，全名，name和page_index。怎么办？

我使用了AFnetworking：

self.manager = [AFHTTPRequestOperationManager manager];
    [self.manager setRequestSerializer:[AFHTTPRequestSerializer serializer]];
    self.manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [self.manager GET:@"http://webapi.test.pl/newsCategoriesForMobileApp/iphone" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];

我不知道如何解析json。

Answer 1

您已经有了一系列词典，您需要执行以下操作

for(NSDictionary *dic in jsonArray){

    NSLog(@"%@, %@, %@",[dic objectForKey:@"category_id"],[dic objectForKey:@"fullname"],[dic objectForKey:@"page_index"]);

}

Answer 2

如果这个数组名为array。你可以通过

获得财产

NSDictionary *dictionary = [array objectAtIndex:page_index];
NSString *fullname = [NSString stringWithFormat:@"%@", [dictionary objectForKey:@"fullname"]];
NSInteger category_id = [[dictionary objectForKey:@"category_id"] integerValue];

Answer 3

这是this

的副本

简而言之：使用NSJSONSerialization class 并检查NSDictionary

如何在ios中解析多个json？
