问题描述
我无法正确了解何时在AppKit应用程式中建立及发布自动发布资料库。
I'm having difficulties to understand exactly WHEN autorelease pools are created and released in AppKit apps.
例如，如果我有一个覆盖init的ApplicationController类，是否有一个自动释放池，它在启动之前创建，并在结束后耗尽？
For example, if I have an ApplicationController class that overrides init, is there an autorelease pool that gets created before it starts and gets drained after it ends?
推荐答案
AppKit应用程序中的主线程运行一个NSRunLoop来处理事件。 NSRunLoop每次处理新事件（或计时器）时都会创建一个新的自动释放池，并在控制流返回到NSRunLoop后将其释放。因此，实质上，每次通过运行循环都有一个新的自动释放池。
The main thread in an AppKit application runs an NSRunLoop to process events. NSRunLoop creates a new autorelease pool every time it processes a new event (or timer) and drains it once control flow has returned to the NSRunLoop. So in essence, every pass through the run loop has a fresh autorelease pool.
