【问题描述】:
我的问题是这个。我有一个在调试模式下构建和运行良好的应用程序,没有崩溃、内存错误等。只要我进行临时构建并尝试在设备上运行它,主线程就会在某个点崩溃,没有明显的原因......我设法从设备日志中获得的堆栈跟踪是......

另一个真正奇怪的事情是,如果您关闭应用程序并在后台停止运行(崩溃后)然后重新启动它,它几乎会立即退出...
<Warning>: Application 'MyApp' exited abnormally with signal 11: Segmentation fault
我认为这是内存访问错误(未初始化的内存访问)。我没有用指针或任何东西做任何疯狂的事情,所以我只能假设这是 CF 库的问题......
任何想法或帮助将不胜感激:)
