我收到了第一份崩溃报告，但我无法弄清楚问题是什么。 幸运的是，由于这个崩溃来 self 的一位同事，所以我可以直接在他的iPhone上测试错误并在他的手机上安装开发版本。
但是，奇怪的是，当我从我的计算机上在他的设备上安装并运行开发版本时，没有崩溃； 仅当从 App Store 下载并安装应用程序时才会出现崩溃。 到目前为止，我无法在任何其他设备上重现该错误(受影响的设备是 iPhone 3G 固件 4.2.1，并且所有操作系统运行速度非常慢)。
崩溃发生在从 UITableViewController (ItemsListTableViewController) 中选择一行之后，此时应该出现详细 View ，但是在构建详细 View (ItemDetailViewController) 期间应用程序崩溃viewDidLoad。
特别是问题似乎局限于类 LocationPathView(ItemDetailViewController View 的 subview )中。
ItemDetailViewController 是 UITableViewController 的子类，并从 viewDidLoad 中的 nib 加载其 tableHeaderView:
[[NSBundle mainBundle] loadNibNamed:@"ItemDetailHeaderView"所有者:self 选项:nil];
(LocationPathView 是 tableHeaderView 的一部分)
加载nib文件时，会调用LocationPathView::awakeFromNib，然后调用LocationPathView::layoutSubviews。崩溃似乎源于layoutSubviews。 在layoutSubviews 中我执行动画: [UIView beginAnimations:nil 上下文:nil]; [UIView setAnimationDuration:0.2]; 由于某些原因，该动画是否会在慢速设备上造成崩溃？在layoutSubviews中设置动画是否正确？
如果有任何帮助，我将不胜感激，
马可

最佳答案
仅应用程序商店版本出现错误让我对用于构建提交二进制文件的项目或目标设置产生怀疑。
您是否使用项目配置来构建提交二进制文件？如果是这样，我首先要查找的是发布版本的 C 宏定义不正确。或者也许它在项目级别是正确的，但在目标级别是错误的。也许你的动画 block 的结束没有正确地发出信号？
使用与应用商店版本完全相同的设置构建应用的临时版本将是一个很好的测试。 (代码签名是唯一的区别。)从设备中删除旧应用程序并通过 iTunes 进行部署以确保确定。
