核心数据在获取数据时返回额外的空值。它返回具有空值的记录（记录数乘以方法调用计数）

Question

AppDelegate * appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];

NSManagedObjectContext *context = [self getContext];

NSEntityDescription *entity = [NSEntityDescription entityForName:@"Category_List" inManagedObjectContext:context];

[request setEntity:entity];

NSError *error1 = nil;

NSArray *results1 = [context executeFetchRequest:request error:&error1];

NSLog(@"Fetch Request Data Count = %lu", (unsigned long)[results1 count]);

我只是调用上下文的重置方法，我的问题就解决了。

[context reset];
