问题描述
当我上次安装 Xcode 3.2.3 Beta 2(支持 OS 4.0)时，它拥有所有 iPhone 设备和模拟器 3.x.
When I last installed Xcode 3.2.3 Beta 2 (OS 4.0 support), it had all the iPhone Device & Simulator 3.x.
现在，更新到 Xcode 3.2.3 Beta 4(支持 OS 4.0)，它不再列出 XCode 中模拟器或设备的 3.x SDK.当我运行为 3.1.2 编写的应用程序时，当前 SDK 被列为缺少基本 SDK"
Now, updated to Xcode 3.2.3 Beta 4 (OS 4.0 support), it no longer lists 3.x SDKs for either simulator or device in XCode. When I run an app that was written for 3.1.2, the current SDK is listed as "base SDK missing"
我知道 3.2.3 将 BASE SDK 更改为 4.0，但为什么 3.x 设备也没有可用?
I'm aware that 3.2.3 changes the BASE SDK to 4.0, but how come none of the 3.x devices are available either?
当我去:
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs
仅有的两个文件是:
iPhoneSimulator3.2.sdk
iPhoneSimulator4.0.sdk
但是，当我去:
/Developer/Platforms/iPhoneOS.platform/DeviceSupport
3.0
3.0.1
3.1
3.1.1
3.1.2
3.1.3
3.2
4.0 (8A274b)
我尝试重新安装最新的 XCode DMG 无济于事.
I've tried re-installing the most recent XCode DMG to no avail.
推荐答案
好像他们删掉了.
如果您正在为较旧的操作系统进行开发，则不应使用 4.0 Beta SDK.
If you are developing for the older OS, you should not be using the 4.0 Beta SDK.
根据发行说明:
iPhone OS 4 beta 4 用于开发仅用于目的.这个软件应该仅安装在专用设备上专为 iPhone OS 4 测试版应用程序开发.不要如果你不安装这个软件有一个专门用于iPhone OS 4 测试版应用程序发展.
iPhone OS 4 beta 4 is for development purposes only. This software should only be installed on devices dedicated exclusively for iPhone OS 4 beta application development. Do not install this software if you do not have a device dedicated exclusively to iPhone OS 4 beta application development.
我建议您将 3.x sdk 与 4.0.0 并行安装.我在我的机器上保留了两个开发者目录/Developer 用于维护为 3.0 和 3.1 编写的应用程序，以及/Developer4.0Beta 用于将应用程序迁移到 4.0 并试用即将推出的新功能.
I would recommend you install the 3.x sdk in parallel to the 4.0. I keep the two Developer directories on my machine /Developer for maintaining apps written for 3.0 and 3.1, and /Developer4.0Beta for migrating apps to 4.0, and trying out the new features that will be available soon.
安装 sdk 时，安装到另一个文件夹的选项有点难以注意到，但诀窍是在安装类型"步骤中按默认目录的向上/向下箭头.点击它们后，您可以选择不同的目录.
The option to install to another folder is a bit hard to notice when installing the sdk, but the trick is to hit the up/down arrows by the default directory on the 'Installation Type' step. After hitting them it will allow you to choose a different directory.
请记住，App;le 不允许您提交使用 Beta SDK 构建的 App，因此我只会使用 4.0 Beta 来构建 4.0 应用程序，请记住，在 GM 之前 API 可能仍会更改发布.
Remember, that App;le won't allow you to submit an App built with a Beta SDK, so I would only use the 4.0 Beta for building 4.0 Apps, keeping in mind that the APIs might still change before the GM is released.
