问题描述
长话短说:如果我在 Mac 上下载并安装新的 Xcode 4.2 Developer Preview 并开始开发新的 iOS 5 应用程序，我还能使用它来开发和发布 iOS 4.x 应用程序吗?
Making the long story short: if I download and install the new Xcode 4.2 Developer Preview on my Mac and start developing new iOS 5 apps, can I still using it for developing and releasing iOS 4.x apps?
我现在无法安装此平台的两个不同版本.可能你们中间有人尝试过并且可以回答.
I do not have the possibility to install two different versions of this platform right now.Probably someone amongst you has tried it and can answer.
iOS 5 测试版与新 Xcode 版本关联的注释链接似乎已损坏.
谢谢！
推荐答案
不可以，您只能通过官方发布的工具提交到应用商店，不能提交测试版.
No, you can only submit to the app store with the official releases of the tools, not the betas.
另请参阅上面 Jano 的评论，在 开发论坛 上已确认您不能使用测试版工具.
See also Jano's comment above, on the dev forums it has been confirmed that you can't use the beta tools.
除非您长期缺乏磁盘空间，否则您可以使用磁盘工具调整当前分区的大小，并在第二个分区上安装新的操作系统，然后在其中安装所有测试版工具.(您也可以在可移动火线驱动器上安装操作系统.)
Unless you're chronically short on disc space, you can use disk tool to resize your current partition and do a new OS install on a second partition that you then install all the beta tools onto. (You can also do an OS install onto a removable firewire drive.)
我更喜欢将所有 Beta 版工具保留在一个完整的独立操作系统安装上，因为这样我就不会出现无法发布应用程序的状态的危险，而发布应用程序正是我赚钱的原因.
I prefer to keep all the beta tools on a complete separate OS installation, as then there's no danger at all that I'll end up a state when I can't publish apps, and publishing apps is what makes me money.
