我有一个NSManagedObject的子类,大多数属性是动态的(由托管对象创建),但我有一些辅助属性,它们被创建为@synthesize.
释放这些物体的正确方法是什么？
- (void)didTurnIntoFault
{
[self.randomVar release];
[super didTurnIntoFault];
}
要么
- (void)dealloc
{
[self.randomVar release];
[super dealloc];
}
解决方法
覆盖didTurnIntoFault并在那里释放它们.管理对象在出现故障时不一定要解除分配.
You are discouraged from overriding
deallocorfinalizebecausedidTurnIntoFaultis usually a better time to clear values—a managed object may not be reclaimed for some time after it has been turned into a fault. Core Data does not guarantee that eitherdeallocorfinalizewill be called in all scenarios (such as when the application quits); you should therefore not in these methods include required side effects (like saving or changes to the file system,user preferences,and so on).
