ios – 自定义警报视图导致iPad旋转时崩溃

我正在显示一个自定义警报视图,该视图是从我的视图控制器中的UIAlertView派生的,当我将设备旋转2-3次时,视图控制器和警报视图都会旋转.但随后该应用程序崩溃,没有明确的线索.我在All Exceptions上有一个断点,但它无法捕捉它.

如果我使用标准的UIAlertView,则不会发生此崩溃.我从其他人那里找到了自定义alertview的代码.这里有什么错误的补充吗？或者我怎样才能获得更多有关正在发生的事情的线索？

    fillColor = [BACkground retain];
    borderColor = [stroke retain];
