Ios 如何处理此数组对象？（目标-C）

首先我有一本字典。我执行一个NSURLRequest，并用请求中的JSON信息加载字典

NSDictionary *json =[NSJSONSerialization JSONObjectWithData:response 
                                                    options:kNilOptions 
                                                      error:&error];

此词典有2个键和2个值。1键=\u NSCFString游戏值：\u NSCFArray*另一个是玩家的IDO。 因为我想要我最近玩的游戏[json objectForKey:@games]。现在我得到了一个包含10个对象的NSArray。下面列出了第一个对象。 我如何才能告诉我的标签，球员玩的是championID的哪个冠军，或者他玩的是哪种游戏类型？因为这是一个完整的对象

如何拆分阵列以获取所有信息

我感谢你的帮助。 谢谢你抽出时间

更新1： self.getRecentGames返回一个NSDictionary，它不是self.recentGames的getter

    self.recentGames = [[NSDictionary alloc] initWithDictionary:self.getRecentGames];
    NSDictionary *dict = [self.recentGames objectForKey:@"games"];
    //now I my dict have 10 object but dict is from type: __NSCFArray

更新2：完成！ 非常感谢您抽出时间。在我检查了数组中的对象所属的类之后，让它显示它是一个NSDictionary。 这么简单，我就能找到答案。

你的回答很有帮助

假设您在问题中显示的结构，您可以执行以下操作：

NSDictionary *game = [games objectAtIndex:0]; // That you did already
NSNumber *championID = [game objectForKey:@"championId"];

根据您的评论进行编辑：

就像前面提到的用户热舔一样，如果您遇到这样的异常，您可能会假设您有一个字典，但最终会得到一个数组。在这种情况下，您将执行两次相同的操作：

NSArray *game = [games objectAtIndex:0]; // That you did already
NSNumber *championID = [game objectAtIndex:indexOfChampionId];

尽管我怀疑后者是否是你真正想要的。因此，您可能需要检查导入数据的部分。

以下是一些代码，这些代码可以帮助您解决问题。当然，这只是一个简单的方案，可以帮助你解决问题

这种隔离的主要思想是递归地创建对象。您必须将所有需要的属性添加到游戏和冠军类中

 NSArray *json =[NSJSONSerialization JSONObjectWithData:response 
                                                options:kNilOptions 
                                                  error:&error];

 NSMutableArray *games = [NSMutableArray array];
 for (NSDictionary *gameDictionary in json) {
   Game *game = [[Game alloc] initWithJSONDictionary:gameDictionary];
   [games addObject:game];
 }

 //games is the table which your game objects




///Game class
@interface Game
   @property (strong, nonatomic) NSArray *champions;

   - (id)initWithJSONDictionary:(NSDictionary *)dictionary;
@end

 @implementation Game
     - (id)initWithJSONDictionary:(NSDictionary *)dictionary
 {
   self = [super init];
   if (self) {
      NSMutableArray *array = [NSMutableArray array];
      NSArray *champions = dictionary[@"championId"];
      foreach (NSDictionary *championDictionary in champions) {
          Champion *champion = [[Champion alloc] initWithJSONDictionary:championDictionary];
          [array addObject:champion];

      }
      self.champions = array;
   }

   return self;
 }

 @end

/// Champion class
 @interface Champion 
   @property (strong, nonatomic) NSString *championId;
   @property (strong, nonatomic) NSString *summonerId;
   @property (strong, nonatomic) NSString *teamId;

   - (id)initWithJSONDictionary:(NSDictionary *)dictionary;

 @end

 @implementation Champion

   - (id)initWithJSONDictionary:(NSDictionary *)dictionary
   {
     self = [super init];
     if (self) {
       self.championId = dictionary[@"championId"];
       self.teamId = dictionary[@"teamId"];
       self.summonerId = dictionary[@"summonerId"]l
     }

     return self;
   }
 @end

每个数组对象都是NSDictionary，对吗？您应该能够使用以下内容访问内部数据：[NSDictionary*[games objectAtIndex:0]valueForKey:@championId]；你有一系列的标签吗？现在还不清楚你到底在挣扎什么——一张详细的清单，或者仅仅从字典中获取一个条目……阅读转储文件。{}包围字典，包围数组。一次剥一层。如果需要，编写一个循环来搜索数组。是的，在一个语句中有一些更奇特的搜索方法，但是如果你编写循环，你会更好地理解你在做什么。顶部是一个名为dict的NSDictionary。在这个dict中有两个键，代表最近10个游戏的NSArray，另一个键不相关。因此，当我做这个NSDictionary*游戏=[games objectAtIndex:0]；NSNumber*championID=[game objectForKey:@championID]；我将得到一个错误：-[\uu NSCFArray objectForKey:]：未识别的选择器发送到实例0xab6c8e0 2014-03-06 13:55:25.612***由于未捕获的异常“NSInvalidArgumentException”，终止应用程序，原因：'-[\uu NSCFArray objectForKey:]：发送到实例0xab6c8e0'@IntegerGaming的选择器无法识别-该错误告诉您有一个数组，而不是字典。请返回并再次查看转储文件，找出错误所在。
