Any guides on using/building with iOS/Mac?

Are there any specific things I should know to get MyGUI built and working on Mac and iOS platforms? For instance do I need to use the right Carbon/Cocoa on Mac, or GLES 1.x/2.0 on iOS?

There were linking issues with dynamic version of MyGUI and some gcc versions, so it might be necessary to use static version library on Mac. What about other things - if you are using Ogre then it doesn't matter which libraries you use.
