使用 AFNetworking2.0 集成了coredata 做本地缓存

这个小 demo 改自afnetworing 提供的 AFIncrementalStore 使用最新版本的AFNetworking

1. 使用该项目提供的 AFCoreData 需要重写 AppDelegate 下 的 - (NSManagedObjectContext *)managedObjectContext ，- (NSPersistentStoreCoordinator *)persistentStoreCoordinato 两个方法

demo

• (NSPersistentStoreCoordinator *)persistentStoreCoordinator { // The persistent store coordinator for the application. This implementation creates and return a coordinator, having added the store for the application to it. if (_persistentStoreCoordinator != nil) { return _persistentStoreCoordinator; }

  // Create the coordinator and store

  _persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]];

  AFIncrementalStore *incrementalStore = (AFIncrementalStore *)[_persistentStoreCoordinator addPersistentStoreWithType:[AppDotNetIncrementalStore type] configuration:nil URL:nil options:nil error:nil]; NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"CoreDataTest.sqlite"];

  NSDictionary *options = @{ NSInferMappingModelAutomaticallyOption : @(YES), NSMigratePersistentStoresAutomaticallyOption: @(YES) }; NSError *error = nil;

  NSString *failureReason = @"There was an error creating or loading the application's saved data."; if (![incrementalStore.backingPersistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); }

  return _persistentStoreCoordinator; }

• (NSManagedObjectContext *)managedObjectContext { // Returns the managed object context for the application (which is already bound to the persistent store coordinator for the application.) if (_managedObjectContext != nil) { return _managedObjectContext; }

  NSPersistentStoreCoordinator *coordinator = [self persistentStoreCoordinator]; if (!coordinator) { return nil; } _managedObjectContext = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSMainQueueConcurrencyType]; [_managedObjectContext setPersistentStoreCoordinator:coordinator];

  NSLog(@"managedObjectContext success %@", _managedObjectContext);

  return _managedObjectContext; }

2. 继承 AFIncrementalStore 重写 + (NSString *)type ，+ (NSManagedObjectModel *)model 两个方法

示例代码见本工程

3. 继承 AFRESTClient 自定义 inflector ，paginator 或者重写 #pragma mark Read Methods 下的方法
