Question

I want to know whether drawing a round UIButton(not rounded rect) is possible.

When I add a round image in a UIButton of type custom, then it looks like a round button. But at the moment the button is clicked the boundary of the button becomes visible, so that it looks like a square button, then again when the click ends it looks like a round button.
I want the button to look like a round button even at the moment the click happens. is this possible?

Answer 1

You’d probably have to create a custom control for that, but do you really need a round button?

Every platform has its UI conventions, and the iPhone is no exception. Users expect the buttons to be rounded rectangles.

UPDATE in response to comment:

If I’m getting this right, you’re not looking for a round button, but rather a clickable (touchable) image.

You can use an UIImageView and its touchesBegan method.

UPDATE 2:

Wait a second. What kind of radio button are we talking about? For some reason I thought you were trying to imitate a real radio. If you’re talking about a radio button group, please use a UISegmentedControl or a UIPicker.
