How to make a view vibrate in an animation in objective-c? [closed]

Answer 1

You can use a CABasicAnimation, and set the repeat count to some small value, while animating the position of the view.layer that you want to vibrate. Note that clipsToBounds for the view must be set to NO. Also be sure to include the QuartzCore framework in the project.

- (void)shakeView:(UIView *)view
{
    CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"position.x"];
    animation.duration = 0.1;
    animation.byValue = @(20);
    animation.autoreverses = YES;
    animation.repeatCount = 10;
    [view.layer addAnimation:animation forKey:@"Shake"];
}
