If you really want to use CGContextShowText (Core Text would be better), you'll have to do the math yourself, i.e. figure out how big the text is, and subtract half of that from the x coordinate of your center point.

To determine the size of the text, you could set the text drawing mode to kCGTextInvisible (using CGContextSetTextDrawingMode), draw the text once, check how far the text position has moved (using CGContextGetTextPosition before and after drawing), and then draw the text again with a visible drawing mode at the correct location.
