退出应用程序时dealloc方法是否正常执行? [英] does dealloc method being executed normally when quitting the application?

问题描述

我使用如下代码(例如在我的 appController.m 中)在我的应用程序终止时进行一些清理......

I use code like the following (inside my appController.m for example) to do some cleanup when my application terminates...

- (void) dealloc {
    [myObject release]; // myObject 's dealloc will not be called either !!!
    [arraySMSs release];
    [super dealloc];
}

当应用退出时这个方法永远不会被调用！为什么 ?有没有更好的地方来做我的清理工作?未被调用的事实解决了内存泄漏问题?还是操作系统负责清理?

This method never get called when the app quits! Why ? Is there a better place to do my clean up ? The fact that is not called addresses memory-leak issues ? Or the OS does take care of clean up ?

谢谢...

推荐答案

系统没有理由确保在应用程序终止时单独释放每个对象.

这样做只会浪费 CPU 周期和用户时间.

There is no reason for the system to ensure that every object is individually deallocated upon application termination.

Doing so is just a waste of CPU cycles and a waste of the user's time.

当应用终止时，系统会以完全自动且不可避免的方式回收该应用使用的所有资源.

When an app is terminated, all resources used by that app are reclaimed by the system in an entirely automatic and unavoidable fashion.

如果您需要在应用程序终止时发生某些事情，请使用应用程序委托的挂钩来执行此操作.但不要依赖那个.用户可以随意强制重启设备或强制退出应用程序.

If you need something to happen at app termination, use the application delegate's hooks for doing so. But don't rely on that. A user may force reboot a device or force quit an application at whim.
