    I am new to IPhone SDK development.

    I created a circle with CGContextAddEllipseInRect() and It is working fine.
    I have some other view (ball) which I want to move inside the circle randomly (Random moving I did already).
    What I want is , If Ball view touches the circle line it has to move back.

    How can I know the whether the ball touches the circle line or not ?

    I searched a lot on the net but no luck ?

    Thank You,
    Ravi,
