RestKit を使用して、次の JSON をコア データにマップしています。
これは私のモデルです:
これは私の方法です:
RKEntityMapping *userMapping = [RKEntityMapping mappingForEntityForName:NSStringFromClass([User class]) inManagedObjectStore:managedObjectStore];
userMapping.identificationAttributes = @[@"id"];
[userMapping addAttributeMappingsFromDictionary:@{
@"birthday":@"birthday",
@"email":@"email",
@"facebook_token":@"facebook_token",
@"first_name":@"first_name",
@"gender":@"gender",
@"interested_in":@"interested_in",
@"last_name":@"last_name",
@"password":@"password",
@"m8_status":@"m8_status",
@"status":@"status",
@"languages": @"languages",
@"hometown":@"hometown",
@"location":@"location",
@"avatar_url":@"avatar_url",
@"mood":@"mood"
}];
RKEntityMapping *findUserMapping = [RKEntityMapping mappingForEntityForName:NSStringFromClass([FindUser class]) inManagedObjectStore:managedObjectStore];
findUserMapping.identificationAttributes = @[@"id"];
[findUserMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"users" toKeyPath:@"users" withMapping:userMapping]];
[manager addResponseDescriptorsFromArray:@[
[RKResponseDescriptor responseDescriptorWithMapping:findUserMapping
pathPattern:@"/v1/users"
keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]
]];
これは JSON の例からオブジェクトを取得しています:
{
"users": [
{
"avatar_url": null,
"birthday": "04/11/1984",
"email": "antonina.duminskaya@wildermancruickshank.co.uk", "first_name": "Antonina",
"gender": "female",
"hometown": null,
"id": "5264ee384d61632c4b2f0000",
"interested_in": [
"male",
"female" ],
"languages": [], "last_name": "Duminskaya", "location": null, "m8_status": null,
"mood": null,
"status": null
} ]
}
ここ:
[objectManager getObjectsAtPath:@"/v1/users" parameters:@{@"session_id":session.id} success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
FindUser *findUsers = [[self.fetchedFindUsersResultsController fetchedObjects] lastObject];
NSLog(@"%@", findUsers.users);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
}];
ログにメッセージがあります:
Relationship 'users' fault on managed object (0x8e964a0) <FindUser: 0x8e964a0> (entity: FindUser; id: 0x8da0790 <x-coredata://083BB731-FDD7-4A35-A174-724F50862A02/FindUser/p1> ; data: {
id = nil;
users = "<relationship fault: 0x8deb260 'users'>";
})
そして、mappingResults には、json に関するすべての結果があります
