UITableViewCell with 'ball' like calendar App

Question

in the iPhone Calendar app, the view to select the calendar for a particular event has a coloured circle next to the calendar name, drawn with a graduated/3D effect of a ball.

Does anyone have any sample code for how this is drawn - I can draw a solid circle in the UITableViewCell, but I'm not sure how to get the 3D effect.

Thanks.

Answer 1

You might be able to do this with a CAGradientLayer using a radial gradient, see this answer.

Also, take a look at the documentation on Gradients.
