Install iOS SDK to new Xcode
提问by vodkhang
I just bought a new Macbook pro and install the Xcode in the disk to my machine, but, that Xcode only has mac sdk. How can I install other iOS sdk in? I just don't want to wait for redownloading the whole Xcode because with my network connection, it takes me up to 8 hours.
我刚买了一个新的 Macbook pro 并将磁盘中的 Xcode 安装到我的机器上，但是，那个 Xcode 只有 mac sdk。如何在其中安装其他 iOS sdk？我只是不想等待重新下载整个 Xcode，因为使用我的网络连接，我最多需要 8 小时。

Apple's Developer Tools Evangelist, Michael Jurwitz, has stated on many many occasions that the developer tools team are aware of peoples frustrations with not having an incremental upgrade system.
Apple 的开发者工具布道者 Michael Jurwitz 曾多次表示，开发者工具团队意识到人们对没有增量升级系统的挫败感。
Unfortunately, no matter how aware they may be, nothing has been done about it for as long as the developer tools have been available.
不幸的是，无论他们多么清楚，只要开发人员工具可用，就没有采取任何措施。
And now that Xcode 4 is available on the Mac App Store, it seems to me that getting an incremental upgrade system is even less likely (although that is just conjecture on my part). I say this because the Mac App Store, like its iPhone counterpart, downloads the new app in full when an update is available.
现在 Xcode 4 在 Mac App Store 上可用，在我看来，获得增量升级系统的可能性更小（尽管这只是我的猜测）。我这样说是因为 Mac App Store 就像它的 iPhone 一样，在有更新可用时会完整下载新的应用程序。
There is nothing more you can do other than wait for the download, I'm afraid.
恐怕除了等待下载之外，您别无他法。

Since they just upgraded their Xcode to version 4 (on 9 March 2011) , it's better for you to download the new Xcode.
由于他们刚刚将 Xcode 升级到第 4 版（2011 年 3 月 9 日），因此您最好下载新的 Xcode。
