次のようないくつかのフィールドで構成されるオブジェクトがあります。
@property (nonatomic, copy) NSString* title;
@property (nonatomic, copy) NSString* body;
@property (nonatomic, copy) NSArray* imageUrls;
@property (nonatomic, copy) NSString* postId;
@property (nonatomic) CLLocationCoordinate2D location;
@property (nonatomic) LTUser *user;
@property (nonatomic) LTPlace *place;
@property (nonatomic, copy) NSArray* comments;
すべてNSString
とカスタム オブジェクト ( LTUser
/などLTPlace
) が適切にマッピングされています。
しかし、どうすればNSArray
of ( imageUrls
- これはNSString
/の配列comments
- これはカスタムオブジェクトの配列 ( LTComment
)) にマップできますか?
"images": [
"http://****.com/images/1385929903887.jpg",
"http://****.com/images/131315313131.jpg",
"http://****.com/images/1351351351.jpg"
]
メイン オブジェクトのマッピング:
RKObjectMapping *userMapping = [RKObjectMapping mappingForClass:[LTUser class]];
[userMapping addAttributeMappingsFromDictionary:@{
@"_id":@"userId",
@"username":@"userName",
@"name":@"name"
}];
RKObjectMapping *placeMapping = [RKObjectMapping mappingForClass:[LTPlace class]];
[placeMapping addAttributeMappingsFromDictionary:@{
@"_id":@"placeId",
@"image":@"name",
@"name":@"image"
}];
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[LTPost class]];
[mapping addAttributeMappingsFromDictionary:@{
@"_id" : @"postId",
@"createdAt" : @"createdAt",
@"body" : @"body",
@"title" : @"title"
}];
[mapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"user" toKeyPath:@"user" withMapping:userMapping]];
[mapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"place" toKeyPath:@"place" withMapping:placeMapping]];
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping
method:RKRequestMethodGET
pathPattern:kLTAPIGetPostsRequest
keyPath:@"posts"
statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[[RKObjectManager sharedManager] addResponseDescriptor:responseDescriptor];
Lコメントのマッピング
RKObjectMapping* commentMapping = [RKObjectMapping mappingForClass:[LTComment class]];
[commentMapping addAttributeMappingsFromDictionary:@{
@"user_name":@"userName",
@"text":@"text"
}];
