Question

我正在尝试确定崩溃的原因（iOS应用），但符号化的崩溃报告仅指向我的主要方法。

8   WxT                               0x00002730 main (main.m:14)
9   WxT                               0x000026e8 start + 32

这里有什么可以帮助我追踪这个问题，或者这对我来说是否毫无用处？ “start + 32”告诉我什么？

N.B。我的应用程序是WxT，它只在报告中引用了几次。我用双星号（**）突出显示了每个出现的情况。

看起来像：

Application Specific Information:
**WxT[3214] has active assertions beyond permitted time:** 
{(
    **<SBProcessAssertion: 0x14005c20> identifier: Suspending process: WxT[3214] permittedBackgroundDuration: 10.000000 reason: suspend owner pid:23 preventSuspend  preventThrottleDownCPU  preventThrottleDownUI** 
)}

系统正在尝试将您的应用移至后台，并且您的网址连接（thread.3）阻止了这种情况发生。

Answer 2

错误消息指出您在后台尝试运行超过10分钟。默认情况下，iOS应用必须在放入后台后的10分钟内停止所有处理。

此崩溃报告中是否有任何有用的信息？
