使用字典进行内存管理/GCC 可能会误解？

在我的代码中的某个地方，我需要从主窗口创建多个窗口，每个窗口都具有特定的配置，但所有实例都是同一控制器对象。

我还需要保留打开的窗口列表，因此每当我打开一个窗口时，我都会将其实例存储在字典中，当窗口关闭时，我会向主窗口发送一条通知，该通知会触发一个方法，然后从该窗口中删除该特定窗口。字典。

我通过创建控制器对象的实例然后在其上调用 [showWindow:self] 来创建窗口。然后我将窗口存储在字典中并退出该方法。

我的问题是，我既不释放也不自动释放新创建的对象，因为从字典中删除窗口时应该这样做（对吗？）。如果我释放或自动释放该对象，则在将其存储在字典中后，当我尝试从字典中删除该对象时，我会收到各种错误。

1）这可能是 Xcode 中的一个简单错误，没有注意到实例存储在字典中吗？

2）无论如何，如果字典存储了对它的引用，为什么 autorelease 会破坏我的窗口？

[更新] 代码如下

CHPostgreSQLMainController *pgMainController = [[CHPostgreSQLMainController alloc]initWithConnectionSettings:(CHPostgreSQLSettingsModel *)entityFromArray error:&error];

// Only display the window if the connection was successful.
if (pgMainController) {
    [pgMainController showWindow:self];

    // Register the window we've opened on the list of open windows
    [listOpenWindows setObject:pgMainController forKey:[entityFromArray connectionName]];
} else {
    //call NSAlert
}

原文

Somewhere on my code I need to create several windows from a main window, each functioning with a specific configuration but all instances of the same controller object.

I also need to keep a list of open windows, so whenever I open a window I store its instance in a dictionary and when the window is closed I send a notification to the main window which fires a method that then removes that specific window from the dictionary.

I create windows by creating an instance of their controller object and then calling [showWindow:self] on it. I then store the window in the dictionary and exit the method.

My problem is that I'm neither releasing nor autoreleasing the newly created object as that should be done when the window is removed from the dictionary (right?). If I do release or autorelease that object, after I store it in the dictionary, I will get all sorts of errors when I try to remove the object from the dictionary.

1) Could this be a simple bug in Xcode that doesn't notice the instance being stored in the dictionary?

2) Anyway, why does autorelease destroy my window, if the dictionary is storing a reference to it?

[Update]
Code below

CHPostgreSQLMainController *pgMainController = [[CHPostgreSQLMainController alloc]initWithConnectionSettings:(CHPostgreSQLSettingsModel *)entityFromArray error:&error];

// Only display the window if the connection was successful.
if (pgMainController) {
    [pgMainController showWindow:self];

    // Register the window we've opened on the list of open windows
    [listOpenWindows setObject:pgMainController forKey:[entityFromArray connectionName]];
} else {
    //call NSAlert
}
