【中文标题】如何调试 iPhone 应用程序崩溃日志。仅在 App Store 购买的版本中崩溃，而不是在开发中【英文标题】：How to debug iPhone app crash log. Crash only in App Store purchased version, not in development 【发布时间】：2011-05-01 09:59:04 【问题描述】：我收到了第一份崩溃报告，但我无法了解问题所在。 幸运的是，由于这个崩溃来自我的一个同事，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，并没有崩溃； 只有从 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，所有操作系统运行速度都很慢）。
崩溃发生在从 UITableViewController (ItemsListTableViewController) 中选择一行之后，此时应该会出现一个详细视图，但是在构建详细视图 (ItemDetailViewController) 期间应用程序崩溃viewDidLoad。
特别是问题似乎在类 LocationPathView（ItemDetailViewController 的视图的子视图）中本地化。 ItemDetailViewController 是 UITableViewController 的子类，并从 viewDidLoad 中的 nib 加载其 tableHeaderView： [[NSBundle mainBundle] loadNibNamed:@"ItemDetailHeaderView" owner:self options: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 我执行动画： [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.2]; 由于某些原因，这个动画会在慢速设备上造成崩溃吗？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

【问题讨论】：
【参考方案1】：只有应用商店版本出错让我怀疑用于构建提交二进制文件的项目或目标设置。
您是否使用项目配置来构建提交二进制文件？如果是这样，我要寻找的第一件事是为发布版本错误地定义了 C 宏。或者它在项目级别是正确的，但在目标级别是不正确的。也许您的动画块的结尾没有正确发出信号？
使用与您的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。 （代码签名将是唯一的区别。）从设备中删除旧应用程序并通过 iTunes 进行部署以确保。
【讨论】：
我正在以标准方式构建我的发布版本：我在 Build Settings -> Code Signing Identity 中选择了我的分发配置文件进行调试和发布行，然后是 Product -> Archive。尚未使用 ad-hoc 版本进行测试，我会尽快发布结果 类似的事情发生在我身上。特别是为 UITableView 中的节标题创建 UIView。如果我存档并“共享”我的应用程序，然后将其安装在 iPhone 4 上，一切都会很好。如果我“提交”相同的构建，我会得到这个：CALayerInvalidGeometry'，原因：'CALayer bounds contains NaN:【参考方案2】：可能是您的动画块阻止了后面运行的主要过渡。尽量避免这种情况。例如 popAviewController 并且在 push 另一种情况之后会导致崩溃，因为您在前一个完成之前正在执行另一个转换。希望你能理解。
【讨论】：
“主过渡”是指由 pushViewController:animated: 启动的动画吗？您应该建议将我的动画放在哪里而不是放在 layoutSubviews 中？ 过渡完成后以上是关于如何调试 iPhone 应用程序崩溃日志。仅在 App Store 购买的版本中崩溃，而不是在开发中的主要内容，如果未能解决你的问题，请参考以下文章
