How to uninstall Xcode and iPhone SDK

My laptop is Thinkpad X61, with only 160GB harddisk. Although I use 25GB for Mac OS for developing, it's still not enough, especially when I need to update the iPhone's SDK.

Each time when I update the SDK, I need to uninstall the Xcode to release at least 4GB space, then install the new one again. But how to uninstall Xcode?

Here is the command that I find from the Internet.

sudo /Developer/Library/uninstall-devtools --mode=all

It can't be more easier, isn't it? Good luck!

关于如何卸载Xcode和iPhone的SDK

我用于iPhone开发的电脑是ThinkPad X61，只有160GB硬盘，我划分了25GB给苹果系统，装完iPhone开发环境后只剩余7G左右了，有时候甚至不满5G。苹果升级SDK相当频繁， 还不乏一些beta版SDK，每次升级，都会遇到硬盘剩余空间不够，不让我安装的问题。那就只能先把原来的Xcode和SDK都卸载掉然后再安装新的啦。 于是出现了卸载的需求，但是如何卸载呢？网上搜了一下后，得知使用一下命令行即可，非常方便。

sudo /Developer/Library/uninstall-devtools --mode=all
