我正在使用返回XML的Web服务从Web请求东西。 只要设备没有锁定,这工作正常。如果用户关闭设备或在配置的超时后锁定设备,则Web服务将失败。我在这里附加了堆栈跟踪。 我在想什么:我没有在我的测试应用程序中使用webservice(通过SOAP调用)的结果做任何事情。它仍然崩溃,试图称为“mprotect”或其他东西。什么是问题,以及如果设备被锁定,我如何让我的应用程序继续运行? 我一直认为锁定不同于推送到背景 - 应用程序应该保持活动状态。在设备被锁定后调用webservice时出现异常
我发现“errno 12”的意思是“内存不足”,但事实并非如此。如果设备没有锁定,测试应用会持续数小时。只要它锁定,它会再做一次请求并崩溃。此外仪器显示(在卢克的问题一样:Explanation of MProtect Errno 12 (ENOMEM))40MB的恒定内存使用
Mprotect failed at 0x5f55000 (length 1396736) with errno 12

?我有接下来的几天工作,以真正解决这个问题! – Luke 2011-04-28 07:57:55
我正在使用MT 4.0.1,Xcode 3,SDK 4.3。如果您找到解决方案,请告诉我。但由于这是一个MT内部,我没有太多的希望。 – Krumelur 2011-04-28 13:49:57
