[英]iPhone: developing with IOS 4.3 on IOS5 device not possible?

原文 2011-10-22 13:11:30 5 1 iphone/ ios

I have ios5 installed on my iPhone device, I am developing an application in xcode using SDK IOS 4.3 I got the error: 我在我的iPhone设备上安装了ios5，我正在使用SDK IOS 4.3在xcode中开发应用程序我收到了错误：

The version of iOS on "John's iPhone” does not match any of the versions of iOS supported for development with this installation of the iOS SDK. Please restore the device to a version of the OS listed below, or update to the latest version of the iOS SDK; which is available here. “John的iPhone”上的iOS版本与iOS SDK的安装支持的任何iOS版本都不匹配。请将设备恢复到下面列出的操作系统版本，或更新到最新版本的iOS SDK;可在此处获得。

I dont want to do either of them, because I have other ongoing projects since months which I started with using IOS 4.3. 我不想做其中任何一个，因为我开始使用IOS 4.3几个月以来还有其他正在进行的项目。 So if I download IOS 5 SDK is that possible that I will mess things up with previous projects? 因此，如果我下载IOS 5 SDK，那么我可能会搞砸以前的项目吗？ And do I have to download all xcode 4.2 again for IOS 5?! 我是否必须再次为IOS 5下载所有xcode 4.2？ and after all.."what the heck is going around?" 毕竟......“到底是怎么回事？”

The error message is pretty clear about what your options are... 错误信息很清楚你的选择是什么......

I suggest you upgrade to Xcode 4.2 and the iOS 5 SDK. 我建议你升级到Xcode 4.2和iOS 5 SDK。 That still allows you to write apps for iOS 4.x, but you get a better version of Xcode and a better compiler (LLVM 3.0) and the ability to develop on your iOS 5 device. 这仍然允许您为iOS 4.x编写应用程序，但是您可以获得更好的Xcode版本和更好的编译器（LLVM 3.0）以及在iOS 5设备上开发的能力。
