我是CoreData新手,刚开始使用RestKit。我正在尝试使用CoreData创建Restkit项目。但我收到此运行时错误:Restartit与CoreData崩溃
断言失败+ NSManagedObject managedObjectContext]
任何想法,我做错了什么?
以下是我的代码到目前为止。至今我还没有创建数据模型。
_objectManager = [RKObjectManager objectManagerWithBaseURL:@"https://api.foursquare.com/v2/venues"];
// _objectManager.objectStore = [RKManagedObjectStore objectStoreWithStoreFilename:@"jiffAssignment.sqlite"];
RKManagedObjectMapping *locationMapping = [RKManagedObjectMapping mappingForClass:[Location class]];
[locationMapping mapKeyPath:@"address" toAttribute:@"address"];
[locationMapping mapKeyPath:@"crossStreet" toAttribute:@"crossStreet"];
[locationMapping mapKeyPath:@"city" toAttribute:@"city"];
[locationMapping mapKeyPath:@"state" toAttribute:@"state"];
[_objectManager.mappingProvider setMapping:locationMapping forKeyPath:@"location"];
// RKObjectMapping *statisticsMapping = [RKManagedObjectMapping mappingForClass:[Statistics class]];
// [statisticsMapping mapAttributes:@"checkinsCount",@"usersCount", nil];
NSLog(@"VenueListController Initialized");
return self;
任何帮助/意见将不胜感激。
