好的，我我启用了NSZombie和...我得到了一个不那么神秘的错误！哇哦！
EDITOk, I've enabled NSZombie and... I get a less cryptic error! Woohoo!

编辑2 借助乐器的Zombie模式，我设法发现了内存地址的内容，如下所示：
EDIT 2 With Instruments' Zombie Mode, I've managed to uncover the contents of the memory address, listed below:

I did notice that -[NSAutoreleasePool release] is called before -[UIApplication sendAction:to:from:forEvent:]... could that be my problem? How would I resolve that?
再次感谢您的回复，每个人都有帮助。

我仍然没有想到这一点......任何人都可以帮忙吗？
I still haven't figured this out... can ANYONE help?
推荐答案
我没弄明白原因，但通过将视图移动到一个 XIB 来解决错误。
I didn't figure out the cause, but the errors were resolved by moving the views into one XIB.
无论如何，谢谢。
