“只关注我自己的业务，iOS应用程序在模拟器中运行。没有做任何非常有趣的事情......只是在视图控制器之间移动......然后暂停...和KABLAMMO！”
我立即查看所有线程的回溯（见下文），但我没有看到任何特别有意义的事情：

（n.b。：在Debug Navigator中，Thread 7列为com.apple.CFSocket.private，Thread 4列为WebThread。）
我想操作系统会关闭我的应用程序，但我不确定原因。
内存使用过多？好吧，我们在模拟器中（但是，是的，我已经很谨慎了 - 在调试期间没有发现内存警告）。
阻止主线程？嗯......不是我知道的！用户界面在发生时似乎足够响应。
运行日志中有什么有趣的东西？不是......而是日常生活中的事情，但就是这样。 ：\
进一步的见解和想法赞赏！
