Discussion

You use this property to get or set the currently active input source.

To set the format, you must first obtain exclusive access to the receiver using lockForConfiguration(). If you do not obtain exclusive access, setActiveInputSource: throws a genericException.

The set method, setActiveInputSource:, throws an invalidArgumentException if you pass a format not present in the formats array.
