ios – RestKit：如何批量处理多个请求并在完成后获得响应？

概述我刚刚发现了RestKit,它将成为我正在做的应用程序的重要部分.当时,我能够将它与核心数据集成,但还没有找到发送多个GET请求的最佳方式. 我需要做的是： 从以下地址获取数据： http://url.com/api/banner/http://url.com/api/category/http://url.com/api/link/ URL将始终采用以下格式：http://url.com/a 我刚刚发现了RestKit,它将成为我正在做的应用程序的重要部分.当时,我能够将它与核心数据集成,但还没有找到发送多个GET请求的最佳方式.

我需要做的是：

从以下地址获取数据：

http://url.com/API/banner/http://url.com/API/category/http://url.com/API/link/

URL将始终采用以下格式：http://url.com/api/SOMETHING/

完成所有请求后,我想运行一个代码(例如调用一个新的视图控制器).最好的方法是什么？

目前,这是我正在使用的代码：

- (ID)init{    self = [super init];    if (self) {        [self setupConnector];        [self setupDatabase];        [self setupMapPings];        [self sendRequests];    }    return self;}- (voID)setupConnector{    // Initialize RestKIT    RKObjectManager *objectManager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://baseURL"]];    self.managedobjectStore = [[RKManagedobjectStore alloc] initWithManagedobjectModel:[[NLCoreData shared] managedobjectModel]];    objectManager.managedobjectStore = self.managedobjectStore;}- (voID)setupDatabase{    Nsstring *storePath = [[NLCoreData shared] storePath];    NSError *error = nil;    NSPersistentStore *persistentStore = [self.managedobjectStore addsqlitePersistentStoreAtPath:storePath fromSeedDatabaseAtPath:nil withConfiguration:nil options:nil error:&error];    NSAssert(persistentStore,@"Failed to add persistent store with error: %@",error);    [self.managedobjectStore createManagedobjectContexts];    self.managedobjectStore.managedobjectCache = [[RKInMemoryManagedobjectCache alloc] initWithManagedobjectContext:self.managedobjectStore.persistentStoreManagedobjectContext];}- (voID)setupMapPings{    RKObjectManager *objectManager = [RKObjectManager sharedManager];    // MapPings    // banner    RKEntityMapPing *bannerMapPing = [RKEntityMapPing mapPingForEntityForname:@"Banner" inManagedobjectStore:self.managedobjectStore];    [bannerMapPing addAttributeMapPingsFromDictionary:@{     @"Title": @"Title",@"ID": @"bannerID",@"created_at": @"created_at",@"image": @"image",@"resource_uri": @"resource_uri",@"updated_at": @"updated_at",@"url": @"url"     }];    bannerMapPing.IDentificationAttributes = @[ @"bannerID" ];    RKResponseDescriptor *bannerDescriptor = [RKResponseDescriptor responseDescriptorWithMapPing:bannerMapPing                                                                                        pathPattern:@"/API/v1/banner/"                                                                                            keyPath:@"objects"                                                                                        statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];    [objectManager addResponseDescriptor:bannerDescriptor];    // category    RKEntityMapPing *categoryMapPing = [RKEntityMapPing mapPingForEntityForname:@"category" inManagedobjectStore:self.managedobjectStore];    [categoryMapPing addAttributeMapPingsFromDictionary:@{     @"name": @"name",@"ID": @"categoryID",@"active": @"active"     }];    categoryMapPing.IDentificationAttributes = @[ @"categoryID" ];    RKResponseDescriptor *categoryDescriptor = [RKResponseDescriptor responseDescriptorWithMapPing:categoryMapPing                                                                                     pathPattern:@"/API/v1/category/"                                                                                         keyPath:@"objects"                                                                                     statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];    [objectManager addResponseDescriptor:categoryDescriptor];}- (voID)sendRequests{    RKObjectManager *objectManager = [RKObjectManager sharedManager];    // Send Request    [objectManager getobjectsAtPath:@"/API/v1/banner/" parameters:nil success:^(RKObjectRequestoperation * operation,RKMapPingResult *mapPingResult) {        NSLog(@"SUCCESS: %@",mapPingResult.array);    } failure: ^(RKObjectRequestoperation * operation,NSError * error) {        NSLog(@"FAILURE %@",error);    }];    // category    [objectManager getobjectsAtPath:@"/API/v1/category/" parameters:nil success:^(RKObjectRequestoperation * operation,error);    }];}

有小费吗？

解决方法 RestKit解决方案是这样的：不是使用方便方法ObjectManager :: getobjectsAtPath,而是必须手动初始化所​​有RKObjectRequestoperations,然后使用 ObjectManager::enqueueBatchOfObjectRequestOperations:progress:completion:方法将它们排入队列.

或者,我认为这实际上更容易和更清洁的解决方案,使用this question接受的答案中描述的调度组.
