Upgrading iphone sdk to 3.0?

Question

这是我第一次升级iphone sdk，想知道除了安装xcode之外，还要使用xcode升级版本吗？

Answer 1

不会，只需安装它，并确保您的iPhone或iPod touch上安装了3.0 ：)，无论如何，这在大多数情况下都是可以的，这是一篇文档，可能会对您有所帮助http://adcdownload.apple.com/iphone/iphone_sdk_3 .0__final / iphone_os_3.0_sdk_readme.pdf

Answer 2

I just installed the updated package and it indicated what would be upgraded, let it finish and then opened my projects and went on. In your projects you will have to make sure you are targeting the 3.0 OS though. And make sure your device is up to date as well(if using hardware for testing)
