iOS JSON解析,包含多个数组的数组

概述我有一个带有多个对象的 JSON数组,我不知道如何将“url”标记作为NSArray或NSDictionary来获取并在Tableview中显示该图像URL.我无法更改JSON数据格式.我该怎么做？ 以下是JSON响应的样子： {"meta": { "total_count": 10},"pages": [ { "id": 7, "meta": 我有一个带有多个对象的 JSON数组,我不知道如何将“url”标记作为NSArray或NSDictionary来获取并在tablevIEw中显示该图像URL.我无法更改JsON数据格式.我该怎么做？

以下是JsON响应的样子：

我正在使用此代码来获取“url”数组. Plz纠正我？

NSArray *imageUrlArray = [[self.JsonData    objectAtIndex:indexPath.row]objectForKey:@"cover_url"];  NSLog(@"IMAGE URL ARRAY:%@",imageUrlArray);  Nsstring *imageUrl = [imageUrlArray valueForKey:@"url"];  NSLog(@"IMAGE URL:%@",imageUrl);

解决方法 查看JsON结构 – http://jsonviewer.stack.hu/

NSMutableArray* imageurlArray = [NSMutableArray new];NSArray* JsonArray = JsonData[@"pages"];for (int i = 0; i<[JsonArray count]; i++) {    NSArray* coverUrlArray = JsonArray[i][@"cover_url"];    for (int t = 0; t< [coverUrlArray count]; t++) {        NSArray* UrlArray = coverUrlArray[t];        for (int x = 0; x<[UrlArray count]; x++) {            [imageurlArray addobject:UrlArray[x][@"url"]];        }    }}NSLog(@"imageurlArray: %@",imageurlArray);//imageurlArray contains all url//In cell for row at indexpath --> use imageurlArray[indexPath.row];
