尝试下面的代码来解析 iOS 5 以上的 JSON 数据

NSError *jsonError = nil;
NSDictionary *tempDict = [NSJSONSerialization JSONObjectWithData:JsonData options:0 error:&jsonError]; 
// here JsonData is nsmutabledata in which your response is append 
NSLog(@"%@",tempDict);

试试这个你会成功使用 iOS 5.0 和 5.0 以上

我想你不知道 JSON 解析。

在谷歌搜索“iOS JSON Parsing”，你会得到很多教程。

让我在这里为您列出一些。

2 中使用 JSON。 iPhone 3的 JSON 框架。如何在 iOS App 中解析 JSON

学习 JSON 解析尝试在您的应用程序中进行，如果您遇到问题，请在此处发布。

您首先需要执行以下操作：将此代码嵌入到 viewdidLoad 函数中：

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http:your URL path for json file"]];
    [self performSelectorOnMainThread:@selector(fetchedData:) withObject:data waitUntilDone:YES];
});

那么你必须添加这个功能：

-(void)fetchedData:(NSData *)responseData{
NSError *error;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
jsonResults = [json objectForKey:@"Content"];
}

[self.tableView reloadData];

}

希望对你有帮助
