Slow circularSpinner

[ghost]

Hi, i see something: When i start circular spinner in Simulator, the speed is more fast (because of memory or cpu is faster then device). When i start it in iPhone 4 or 3gs, the circular spinner is very very slow. Can you explain why and how i can perform it? Did you use shadow in circular spinner?

Thanks.

I fixed this bug.
All you need is replace timerFired method implementation with next:
- (void) timerFired:(NSTimer *)timer // for TJCircularSpinner calls { _angle = _angle+_rotationAngle; if (_angle>360) { _angle = 00.00; } NSNumber *rotationAtStart = [self.layer valueForKeyPath:@"transform.rotation"]; CATransform3D myRotationTransform = CATransform3DRotate(self.layer.transform, M_1_PI, 0.0, 0.0, 1.0); self.layer.transform = myRotationTransform; CABasicAnimation *myAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"]; myAnimation.duration = 0.1; myAnimation.fromValue = rotationAtStart; myAnimation.toValue = [NSNumber numberWithFloat:([rotationAtStart floatValue] + M_1_PI)]; [self.layer addAnimation:myAnimation forKey:@"transform.rotation"]; }
The main performance issue for all code is redrawing UI elements. There is no need to do it. All you need is draw UI once time and just transforming it in future.

I will check performance on iPhone 4 and 3GS devices and update the fix.
Thanks for using and giving your valuable input to improve this library.
