我需要用 RestKit 映射一个嵌套数组，而且我几乎得到了它（我想）。

我需要映射的 JSON，看起来像这样

[
    {
        _id: "5058670183970a0002000450",
        app_store_url: "http://itunes.apple.com/app/culturonda-alto-adige-sudtirol/id534467629",
        comments: [
            {
                _id: "5058670783970a0002000456",
            },
            {
                _id: "50588d7f83970a000200065c",
            }
        ]
    }
]

我存储信息的控制器如下所示：

#import <Foundation/Foundation.h>
#import "CommentData.h"

@interface DesignData : NSObject
    @property (retain, nonatomic) NSString *designId;
    @property (retain, nonatomic) NSSet *commentsRelationship;
@end

和：

#import <Foundation/Foundation.h>

@interface CommentData : NSObject
    @property (retain, nonatomic) NSString *commentId;
@end

我的映射如下所示：

RKObjectManager *objectManager = [RKObjectManager sharedManager];

RKObjectMapping *commentsMapping = [RKObjectMapping mappingForClass:[CommentData class]];
[commentsMapping mapKeyPathsToAttributes:@"_id", @"commentId", nil];

RKObjectMapping *designMapping = [RKObjectMapping mappingForClass:[DesignData class] ];
[designMapping mapKeyPathsToAttributes:@"_id", @"designId", nil];

[designMapping mapKeyPath:@"comments" toRelationship:@"commentsRelationship" withMapping:commentsMapping];

[objectManager.mappingProvider setMapping:designMapping forKeyPath:@""];

评论进入一个数组，但它没有存储在评论控制器中。如果我像这样在 objecloader 回调中显示注释：

DesignData *designData = [objects objectAtIndex:0];
NSLog(@"Loaded %@ ", designData.commentsRelationship);

它给了我：

2012-10-20 22:37:55.258 RestKitTest5[4144:c07] Loaded {(
                                                        <CommentData: 0x8689730>,
                                                        <CommentData: 0x868bed0>,
                                                        <CommentData: 0x868bfe0>,
                                                        <CommentData: 0x868bf50>
                                                        )}

这是一个开始。但我不能这样做：

DesignData *designData = [objects objectAtIndex:0];
NSLog(@"Loaded %@ ", designData.commentsRelationship.commentId);

那么如何将整个内容存储为数组呢？

替换这条线后，我为我工作：

[designMapping mapKeyPath:@"comments" toRelationship:@"commentsRelationship" withMapping:commentsMapping];

和：

[designMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"comments" toKeyPath:@"commentsRelationship" withMapping: commentsMapping]];

我已经做对了，最后我只是愚蠢。

我得到了数组，并且数组中的对象是正确的类型（CommentData），所以我所要做的就是遍历数组，然后我可以从那里分别处理每个对象。
