CoreDataGeneratedAccessors - removeObject刪除對象嗎？

Question

當我生成CoreData實體我的課我得到生成的方法

@interface Site (CoreDataGeneratedAccessors) 
- (void)addSearchesObject:(Search *)value; 
- (void)removeSearchesObject:(Search *)value; 
- (void)addSearches:(NSSet *)value; 
- (void)removeSearches:(NSSet *)value; 

@end 

所以我的問題是非常簡單的，當我打電話removeSearchesObject：myObject的我一定要刪除它嗎？

[site removeSearchesObject:[[fetchedResultsController fetchedObjects] objectAtIndex:indexPath.section]]; 
     [context deleteObject:[[fetchedResultsController fetchedObjects] objectAtIndex:indexPath.section]]; 

這裏是生成的代碼（從doc）

- (void)removeEmployeesObject:(Employee *)value 

{ 

    NSSet *changedObjects = [[NSSet alloc] initWithObjects:&value count:1]; 



    [self willChangeValueForKey:@"employees" 

      withSetMutation:NSKeyValueMinusSetMutation 

      usingObjects:changedObjects]; 

    [[self primitiveEmployees] removeObject:value]; 

    [self didChangeValueForKey:@"employees" 

      withSetMutation:NSKeyValueMinusSetMutation 

      usingObjects:changedObjects]; 



    [changedObjects release]; 

}

是的，如果你刪除對象，你仍然需要將其刪除。系統不知道你是否要將它重新連接到別的地方。另一方面，如果刪除對象，只要模型中的刪除規則設置爲「Nullify」，它就會自行刪除。欲瞭解更多信息，你應該檢查刪除規則documentation。
