Custom UISwitch to show YES / NO

One of the great things about iPhone development are that there are lots of user interface pieces that are easy to put together and customize. Unfortunately there are also a lot of pieces which don't have all the basic customizations that may people want. The UISwitch is one of those.

Its size, colors, and ON / OFF text are not changeable. Fortunately there are several great re-implementations (and a few hacks that use restricted API calls) to modify all this. One that I am using is the RCSwitch class available here.

Second I added an init method to the RCSwitch.m base class which called the usual init function but provided the default frame size. This works fine since I am positioning the x and y coordinates using the "center" property:

The final result looks and behaves just like the original UISwitch, but is actually completely rewritten using the UIControl class. My switches now look like this:
