copied!<p>Once you have individual time values (it sounds like you've figured this out already) you can position your hands as needed. </p> <p>This means it's time to brush up on your math skills. I think this'll give you a start:</p> <p>A circle has 360 degrees in it. This means that for whatever time unit we get, we divide by the maximum value of that time unit to get a fraction and multiply the result by 360 (instead of 100 like a percentage) to get our number of degrees. </p> <p>So, if we had 23 seconds:</p> <blockquote> <p>23/60 = 3.8333<br>3.8333 x 360 = 138 degrees</p> </blockquote> <p>Now we know how many degrees to rotate our object. I would get a designer to make you some nice hand images and put them in UIImageViews. Then, you can rotate them around their origins like so:</p> <pre><code>secondHandImage.transform = CGAffineTransformMakeRotate(secondAngle);</code></pre> <p>Good luck :)</p> <p><strong>EDIT:</strong> Let's assume that our hands are on 10:10. If we wanted to move them to 01:00 we would do something like the following. Tweak it as needed. </p> <pre><code>//Calculate angles: float minutesAngle = (0/60)*360; float hoursAngle = (10/12)*360; //Begin the animation block [UIView beginAnimations:@"moveHands" context:nil]; [UIView setAnimationDuration:0.5]; minutesHand.transform = CGAffineTransformRotate(minutesHand.transform, minutesAngle); hoursHand.transform = CGAffineTransformRotate(hoursHand.transform, hoursAngle); [UIView commitAnimations]; </code></pre>
