问题
In the developer center there are two different downloads for the SDK, one for Leopard and one for Snow Leopard. Which do I download?
Also do I have to download a separate copy of xcode as well or is it part of the download?
Thank you.
回答1:
Snow Leopard is the version of Mac OSX slated to be released in late 2009, if you do not have Snow Leopard you should use the Leopard version.
- Leopard = Mac OS X Version 10.5.x
- Snow Leopard = Mac OS X Version 10.6.x
(you can find this by clicking on the apple at the top left of the screen, and clicking "about this mac")
Xcode is part of the SDK download.

- For the beginner, and for production-level work: Leopard and SDK 3.0
- For the adventurous developer who likes to live dangerously (or get ahead of the curve on new features): Snow Leopard and SDK 3.1
Both of the SDKs are available on Apple's iPhone Developer Center, but you'll have to register (which is free until you want to test on a device or submit an app).
Snow Leopard can only be downloaded by "ADC Premier and Select Members" right now (via the Mac Dev Center, as far as I know.
