我在我们的游戏中遇到了一个崩溃错误，我已经尝试了很长时间，但没有取得太大进展。我有一组大部分可重复的步骤来导致它，我已经能够在连接时重现它，在它发生之前弄清楚我的代码的最后一点是什么。我已经设置了断点并逐步通过它......但是当崩溃发生时，它总是在程序集中，并且崩溃报告似乎总是来自运行循环，这不是很有帮助。

这是我如何重现该错误（大约 1/3 的时间）...

进入游戏关卡选择界面，场景完成4/5关卡。级别选择器将位于第 5 级。立即选择第 4 级。选择环将移动到第 4 级的气泡，大约 1/3 的时间……第 5 级的气泡会无缘无故消失，游戏会崩溃。

最令人沮丧的事情之一是，它不会总是返回相同的崩溃报告。将会出现两个不同的版本。

希望有人可以帮助解决这个问题，因为我很困惑。

根据 WDUK 上面提供的帮助，我找到了这个问题的答案。

问题是由屏幕上的一个 UIButtons 自动释放引起的。发生这种情况是因为我有一个单独的属性 currentSelectedLevelButton 被保留。但是，在部分代码中，我设置了 currentSelectedLevelButton 而不是 self.currentSelectedLevelButton。由于我没有使用该属性作为设置器，因此未使用该属性的保留部分，然后将其自动释放。修复它涉及找到我设置 currentSelectedLevelButton 的所有位置并将其更改为 self.currentSelectedLevelButton。
