代号 一个应用程序在模拟器上运行但在 iPhone 设备上反复崩溃
Codename One application works on simulator but crashes repeatedly on iPhone device
将我的第一个应用程序发送到我的 iPhone 后，我发现在使用导航命令或按钮操作事件导航时它会反复崩溃，而模拟器不会。
我无法从崩溃报告（下面的片段）中确定原因是什么，想知道我应该如何进行调试。我看到线程 2 触发了它（崩溃）并且是一些无效地址或其他什么？任何指针将不胜感激。

这可能是由于切换到 new Codename One VM 而导致的回归。您可以通过使用构建参数 ios.newVM=false 遵循 post 中建议的临时解决方法，但是如果您有一个使新 VM 崩溃的简单测试用例，我建议您在问题跟踪器中提交一个问题。
