Xcode版本是6.1
Unity版本是4.54f1和NGUI 2.6.1
我确定在 UnityEngine 中运行时，在控制台上不会记录任何错误，但是在 iPhone 中运行时，它大约每小时崩溃一次。
我试图使用 dSYM 来跟踪错误，但是我所看到的只是内存地址，我听不懂。
这是我的设置:
脚本调用优化为
"Slow and Safe" 优化级别为"None[-O0]" 线程0崩溃:

最佳答案
跟踪的第3行 mono_handle_native_sigsegv 表示您正在尝试访问NULL对象。
如果您没有在编辑器中看到此信息，但是在设备上看到了，请记住，不同设备上的时序会有所不同。可能由于时序差异，导致问题的行在对象在编辑器中无效之前被调用，而在设备上之后被调用。
您似乎在响应OnClick消息时发生了它。
