You probably have an over-release or dangling observer -- Run with Zombies.
You're likely messaging an instance that has been destroyed (while holding an invalid reference to it), but a separate instance has been allocated at the same address since the previous one at that address was destroyed.

你可能有一个过度释放或悬挂的观察者——与僵尸一起奔跑。
您可能正在向已被销毁的实例发送消息（同时持有对其的无效引用），但自从该地址的前一个实例被销毁以来，已在同一地址分配了一个单独的实例。

the object that does have the selector astroidImage has been released, you meant to hold on to it but got it wrong somewhere.
