UISegmentedControl with custom prev/next buttons

I am trying to reach the following result

here

I know how to configure the segmented control but I was wondering how to get the same icons ... I tried to do it with photoshop but I just can't manage to achieve the same quality !

I heard th开发者_StackOverflow中文版ere is a possibility to use the "Apple symbols font" available on Mac (which contains these icons), could you show me how to get these symbols ?

Or if you have a link to these precise icons (for free) It would be nice too.

Thank you,

The NavBar sample code in the apple developers page contains these two images and shows you how to implement them.
