How can I implement semicircle-shaped buttons in iPhone applications

Question

I got a iPhone app design made in Photoshop. I converted the PSD file to PNG format.

I found it difficult to implement, especially on some portions like semicircle-shaped buttons.

How can I implement this semicircle-shape as two buttons?

Answer 2

Draw two quarter circle images in Photoshop, saved at PNG files. In your nib file make two custom buttons the size of the quarter circles, each with one of these quarter circle images. Place the two buttons next to each other. You can embellish the buttons by drawing the various states of the button as separate PNG files, and add those images to the nib file definition of the buttons.
