Vibrate UIView. Add Shivering effect to the view.


#define DEGREES_TO_RADIANS(angle) ((angle) / 180.0 * M_PI)



+ (void)vibrateView:(UIView*)view
{
    CABasicAnimation *shiverAnimationR;
    shiverAnimationR = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
    shiverAnimationR.toValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(1)];
    //shiverAnimationR.toValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(-10)];
    shiverAnimationR.duration = 0.1;
    shiverAnimationR.repeatCount = 1000000.0; // Use A high Value
    shiverAnimationR.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];

    [view.layer addAnimation: shiverAnimationR forKey:@"shiverAnimationR"];


    CABasicAnimation * shiverAnimationL;
    shiverAnimationL = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
    //shiverAnimationL 2.toValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(10)];
    shiverAnimationL.toValue = [NSNumber numberWithFloat:DEGREES_TO_RADIANS(-1)];
    shiverAnimationL.duration = 0.1;
    shiverAnimationL.repeatCount = 1000000.0;
    shiverAnimationL.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];

    [view.layer addAnimation: shiverAnimationL forKey:@"shiverAnimationL"];
