自动引用计数（ARC）表示禁止调用[super dealloc] ...有什么替代方案？ [英] Automatic Reference Counting (ARC) says that invoking [super dealloc] is forbidden...what is the alternative?

问题描述

我开始使用iOS5，我已经为我的项目启用了ARC。我有一个类在deallocation我保存该对象的状态。

I'm starting to use iOS5 and I've enabled ARC for my project. I have a class where on deallocation I save the state of that object.

-(void)dealloc {
    [self save];
    [super dealloc];
}

但是，在ARC下， [super dealloc] 是不允许的？我认为如果在这种情况下你没有在超类上调用dealloc方法它被认为是一个错误？

However, under ARC, [super dealloc] is not allowed? I thought that it was considered a bug if you don't invoke the dealloc method on the super class in this situation?

那么现在解除对象的适当方法是什么？

So what is the appropriate way to dealloc objects now?

推荐答案

iOS 5中的ARC属于NDA。也就是说，根据clang官方网站上的公开信息判断，你只是不写 [super dealloc] 。这是由编译器。请参阅规范的 7.1.2 。

ARC in iOS 5 is under NDA. That said, judging from publicly available information at the official site of clang, you just don't write [super dealloc]. That's generated automatically by the compiler. See the clause 7.1.2 of the specification.
