How do I switch keyboard layout programmatically in MacOS X?

Question

Hi all,

how do I switch keyboard layout (AKA input source) programmatically in MacOS X in a Cocoa/Objective C program? Thanks in advance.

I've not had occasion to try this, but I think you want the functions in text input source services. Note that these are Carbon functions, though usable from Cocoa -- you'll need to add the Carbon framework to your project in order to use them.
