对此进行了太多讨论，但我无法弄清楚如何解决我的问题。

这是我从 WorldWeatherOnline 获得的 JSON 数据。JSON 是有效的。但我不知道如何解析它。这是我的代码，后跟 JSON。请帮忙！

NSError* errorInfo;
NSDictionary *parsedJSON = [NSJSONSerialization JSONObjectWithData:self.wwoWeatherData options:kNilOptions error:&errorInfo];

NSArray* temp = [parsedJSON objectForKey:@"temp_C"];
NSLog(@"%@", temp);

   {
   “数据”：{
      “现在的状况”：[
         {
            “云罩”：“0”，

您解析的 json 包含一个名为data. 在该字典中是一个数组current_condition。继续深入研究数据结构以找到您正在寻找的属性：

NSDictionary *data = [parsedJSON objectForKey:@"data"];
NSArray *currentConditions = [data objectForKey:@"current_condition"];
NSDictionary *condition = [currentConditions objectAtIndex:0];
NSString *tempC = [condition objectForKey:@"temp_C"];
