当我在设备上构建应用程序时收到警告 - 这是什么意思？
有人可以帮我解决这个警告吗？当我在我的设备而不是模拟器上执行 buildandRun 时，我会在控制台上看到此信息。最后一行到底是什么意思？ 我正在使用 XCode 3.2。当我将应用程序部署到应用程序商店时，我应该担心这一点吗？
控制台打印输出：

could someone please help me with this warning. I get this on my console when I do a buildandRun on my device rather than my simulator. What exactly does the last line mean?
I'm using XCode 3.2. Should I be concerned about this when I deploy my apps to the app store?

转到路径并删除此文件夹 -
/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148a)/
，当您再次连接设备时，它会要求您重新收集操作系统，因此请按收集。
Go to the path and delete this folder -
/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148a)/
and when you will connect your device again it will ask you to recollect the os, so press collect.
不，没关系。这只是一个警告，并且是来自调试器（而不是编译器）的警告。这不会影响应用程序在 App Store 上发布时的情况，并且在开发过程中也不太可能造成任何问题。
No, it's fine. It's just a warning, and one from the debugger (not the compiler). This won't affect the app when published on the App Store and it's unlikley to cause any problems while developing either.
