I am still on the analog clock thing here. I am drawing the hands of the clock myself and would like to programmatically rotate them.
For instance this is how I am constructing the hour hand: rootLayer = [CALayer layer]; rootLayer.frame = CGRectMake(240, 160, 240, 160); self.view.layer addSublayer:rootLayer]; CGPoint center = CGPointMake(0, 0); hourHandPath = CGPathCreateMutable(); CGPathMoveToPoint(hourHandPath, nil, center.x, center.y+10); CGPathAddLineToPoint(hourHandPath, nil, center.x, center.y - 50); CGPathCloseSubpath(hourHandPath); hourHandLayer = [CAShapeLayer layer]; hourHandLayer.path = hourHandPath; UIColor *myStrokeColor = [UIColor colorWithHue:0.2 saturation:1 brightness:0.1 alpha:1.0]; hourHandLayer.strokeColor = myStrokeColor.CGColor; hourHandLayer.lineWidth = 3.0; [rootLayer addSublayer:hourHandLayer]; Now I am attempting to initially set it rotation: NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit| NSMinuteCalendarUnit |NSSecondCalendarUnit; NSDate *date = [NSDate date]; NSDateComponents *comps = [gregorian components:unitFlags fromDate:date]; int h = [comps hour]; int m = [comps minute]; int s = [comps second]; CGAffineTransform cgaRotateHr = CGAffineTransformMakeRotation(DEGREES_TO_RADIANS( h*30+m/2 )); CGAffineTransform cgaRotateMin = CGAffineTransformMakeRotation(DEGREES_TO_RADIANS( m*6+s/10 )); *//This is not working - must be another method to do this I am unaware of at the moment...* [hourHandLayer setTransform:cgaRotateHr]; What is the proper way to apply the rotation? A CABasicAnimation with a duration of 0 and a repeat count of 0?
