我在iOS 8.2上运行我的应用程序。应用程序正在运行并且很好地执行我的代码，在我测试的一个设备上它崩溃了。我该怎么办呢？为什么它会在特定设备上崩溃？
我需要帮助我的崩溃报告从xcode重新进行sybolized：

这是我的猜测：
＆＃34; com.SDS.LEAF-v2未能及时退出＆＃34;
...根据给出的信息，我只能得出结论，它在较慢的设备（即iPhone4,1）上崩溃，并且它不会在您的主设备上崩溃，这可能会更快。
答案 1 :(得分：0)
查看上面给出的日志是我的假设
13 UIKit 0x2ecd0c9c - [UINavigationController _startTransition：fromViewController：toViewController：] + 172
当您从一个视图控制器执行某些转换到另一个视图控制器时，似乎会导致崩溃，请检查导航控制器，并在转换时添加断点。
硬件型号：iPhone4,1
特定应用信息： com.SDS.LEAF-v2无法及时退出
这看起来您的应用程序在 iPhone型号4S （here's the list if you want to have a look）中导致问题，而其他特定信息看起来就像您的应用程序名称。
要了解崩溃的全部内容，我建议symbolicating your crash reports
如果应用程序在其他设备上正常运行，那么请不要妄下结论，然后检查iPhone 4S的解决方法。
