SDL_uikitview.m

Add this little function to a .m file of your choice. I chose SDL_uikitview.m as it already has the iPhone specific keyboard functions in it.
I'm pretty sure you can choose any *.m file in /Library Source/video/uikit from the Xcode project file.

Make sure this function is added after @implementation ... @end.
