我该如何处理这个Array对象？ （Objective-C）

Question

首先我有一个NSDictionary。我执行NSURLRequest并从请求中加载带有JSON信息的字典。

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

本字典有2个键值和2个值。 1键=（_ NSCFString）“games”（value：（_NSCFArray *）），另一个是“id”（玩家）。 因为我想要最近的比赛我做[json objectForKey:@"games"]。现在我得到一个有10个对象的NSArray。第一个对象列在下面。 如何向我的标签说出哪位冠军（来自冠军ID）玩家玩过或他玩过哪种游戏类型？因为这全部在1个对象中。

如何拆分数组以获取所有信息？

我很感激每一个帮助。 谢谢你的时间。

更新1： self.getRecentGames返回一个NSDictionary中（它是不是从self.recentGames吸气）

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：完了！ 非常感谢您的时间。在我检查数组中的对象是否显示它的类之后，它是一个NSDictionary。 非常简单，我只是可以找到它。 你的答案非常有帮助！

Answer 1

假设你在你的问题表明的结构，你可以做到以下几点：

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

编辑根据您的评论：

就像用户的热点舔提到的，如果你得到这样一个异常，你可能会认为你有一本字典，但最终会得到一个数组。虽然我怀疑后者是你真正需要的

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

：在这种情况下，你会做同样的两倍。所以，您可能需要检查导入数据的部分。

Answer 2

这里有一些代码应该可以帮助你解决你的问题。当然，这只是简单的方案，应该可以帮助你解决你的问题。

该solation的主要思想是递归地创建对象。您必须将所需的所有属性添加到游戏和Champion类。

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
