我的应用程序遇到了一个奇怪的崩溃问题，该问题仅在 10.5 上发生。它不会一直发生，但它会在启动时发生，似乎是在 nib 加载时。（BWTransparentScrollView 出现在崩溃报告中，但那里的崩溃发生在 initWithCoder: 中，如果我从项目中删除 BWToolkit，我仍然可以触发崩溃。）
事实上，我的笔尖中的两个 IKImageBrowserView 对象似乎有问题。如果我从笔尖中删除它们，崩溃似乎永远不会发生（尽管我的 UI 搞砸了，因为这两个视图对于界面来说是必不可少的）。
Interface Builder 不会通知我有关 IKImageBrowserViews 的任何问题。
以下是此问题的典型崩溃报告：
