Code Fragment:
Just a idea like that.You can use perform on main thread using a class method and pass your structure as argument.+ (void)finalize {[[self class] performSelectorOnMainThread:@selector(destroyNotThreadSafeStruct:) withObject:[NSValue valueWithPointer:myStruct]];} + (void)destroyNotThreadSafeStruct:(id)myStruct { void *struct = [myStruct pointerValue];// perform cleanup. As this is a class method, it does not resurect the object.}
Yup. That is the way to do it. Whatever you do, *do not block in your -finalize methods*. Especially if you blocking on main thread processing.
Very Bad Things Can Happen.Notably, your performance can go to hell. And it is quite easy to lock things up.
In this case, the above pattern should not cause that to happen.In general, -finalize should *only be used to release memory not being managed by GC*.
