Dylib destructor not called

Question

I have dylib that I can download via injection on mac os x. The design challenge works well.

 __attribute__((constructor))
 static void initialize()

But the destructor is not called? In this way, resources initiate leaks.

__attribute__((destructor))
static void destroy()

• Does dylib remove automatically if the application shuts down?
• Is dylib injection injected automatically when the application loads?
• How can we unload dylib from an application at runtime? As an injection code, I can access a private area. Is there a team for this?
