UIView shake animation

i'm trying to make a UIView shake when a button is pressed.

I am adapting the code I found on http://www.cimgf.com/2008/02/27/core-animation-tutorial-window-shake-effect/.

However, by trying to adapt the following code to shake a UIView, it does not work:

- (void)animate {
    const int numberOfShakes = 8;
    const float durationOfShake = 0.5f;
    const float vigourOfShake = 0.1f;

    CAKeyframeAnimation *shakeAnimation = [CAKeyframeAnimation animation];

    CGRect frame = lockView.frame;

    CGMutablePathRef shakePath = CGPathCreateMutable();
    CGPathMoveToPoint(shakePath, NULL, CGRectGetMinX(frame), CGRectGetMinY(frame));

    for (int index = 0; index < numberOfShakes; ++index) {
	    CGPathAddLineToPoint(shakePath, NULL, CGRectGetMinX(frame) - frame.size.width * vigourOfShake, CGRectGetMinY(frame));
	
	    CGPathAddLineToPoint(shakePath, NULL, CGRectGetMinX(frame) + frame.size.width * vigourOfShake, CGRectGetMinY(frame));
    }

    CGPathCloseSubpath(shakePath);

    shakeAnimation.path = shakePath;
    shakeAnimation.duration = durationOfShake;


	[lockView.layer addAnimation:shakeAnimation forKey:@"frameOrigin"];

}

I wrote that post. It's overkill for a UIView, plus the parameters are geared toward an OSX app. Do this instead.

CABasicAnimation *animation = 
                         [CABasicAnimation animationWithKeyPath:@"position"];
[animation setDuration:0.05];
[animation setRepeatCount:8];
[animation setAutoreverses:YES];
[animation setFromValue:[NSValue valueWithCGPoint:
               CGPointMake([lockView center].x - 20.0f, [lockView center].y)]];
[animation setToValue:[NSValue valueWithCGPoint:
               CGPointMake([lockView center].x + 20.0f, [lockView center].y)]];
[[lockView layer] addAnimation:animation forKey:@"position"];

You'll have to play with the duration and repeatCount parameters as well as the x distance from center in the from and to values, but it should give you what you need. I hope that helps. Let me know if you have any questions.

Swift 3.0

let midX = lockView.center.x
let midY = lockView.center.y

let animation = CABasicAnimation(keyPath: "position")
animation.duration = 0.06
animation.repeatCount = 4
animation.autoreverses = true
animation.fromValue = CGPoint(x: midX - 10, y: midY)
animation.toValue = CGPoint(x: midX + 10, y: midY)
layer.add(animation, forKey: "position")

I prefer this solution that has a nice springy behavior, ideal for a wrong-password shake animation.

view.transform = CGAffineTransformMakeTranslation(20, 0);
[UIView animateWithDuration:0.4 delay:0.0 usingSpringWithDamping:0.2 initialSpringVelocity:1.0 options:UIViewAnimationOptionCurveEaseInOut animations:^{
	view.transform = CGAffineTransformIdentity;
} completion:nil];

###Swift 3

extension UIView {
    func shake() {
        self.transform = CGAffineTransform(translationX: 20, y: 0)
        UIView.animate(withDuration: 0.4, delay: 0, usingSpringWithDamping: 0.2, initialSpringVelocity: 1, options: .curveEaseInOut, animations: {
            self.transform = CGAffineTransform.identity
        }, completion: nil)
    }
}

Here's my nice and simple looking version This simulates the shake you get on Mac OS X when you do an incorrect login. You could add this as a category on UIView if you like.

@implementation UIView (DUExtensions)

- (void) shake {
    CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"transform.translation.x"];
    animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
    animation.duration = 0.6;
    animation.values = @[ @(-20), @(20), @(-20), @(20), @(-10), @(10), @(-5), @(5), @(0) ];
    [self.layer addAnimation:animation forKey:@"shake"];  
}

@end

The animation values are the x offset from the views current position. Positive values shifting the view to the right, and negative values to the left. By successively lowering them, you get a shake that naturally loses momentum. You can tweak these numbers if you like.

Here is the swift version as an extension in case anybody needs it

extension UIImageView{
    func vibrate(){
        let animation = CABasicAnimation(keyPath: "position")
        animation.duration = 0.05
        animation.repeatCount = 5
        animation.autoreverses = true
        animation.fromValue = NSValue(CGPoint: CGPointMake(self.center.x - 2.0, self.center.y))
        animation.toValue = NSValue(CGPoint: CGPointMake(self.center.x + 2.0, self.center.y))
        self.layer.addAnimation(animation, forKey: "position")
    }
}

This will animate an small UIImageView (around 15x15). If you need to animate something bigger you may want to change the 2.0 factor of movement to something greater.

Based on @bandejapaisa answer, UIView extension for Swift 3

extension UIView {
    func shake() {
        let animation = CAKeyframeAnimation(keyPath: "transform.translation.x")
        animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear)
        animation.duration = 0.6
        animation.values = [-20, 20, -20, 20, -10, 10, -5, 5, 0]
        layer.addAnimation(animation, forKey: "shake")
    }
}

You can try this piece of code:

to call the code below, use: [self earthquake:myObject];

#pragma mark EarthQuake Methods

- (void)earthquake:(UIView*)itemView
{
    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); 

    CGFloat t = 2.0;

    CGAffineTransform leftQuake  = CGAffineTransformTranslate(CGAffineTransformIdentity, t, -t);
    CGAffineTransform rightQuake = CGAffineTransformTranslate(CGAffineTransformIdentity, -t, t);

    itemView.transform = leftQuake;  // starting point

    [UIView beginAnimations:@"earthquake" context:itemView];
    [UIView setAnimationRepeatAutoreverses:YES]; // important
    [UIView setAnimationRepeatCount:3];
    [UIView setAnimationDuration:0.05];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(earthquakeEnded:finished:context:)];

    itemView.transform = rightQuake; // end here & auto-reverse

    [UIView commitAnimations];
}

- (void)earthquakeEnded:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context 
{
    if ([finished boolValue]) 
    {
        UIView* item = (UIView *)context;
        item.transform = CGAffineTransformIdentity;
   }
}

You can call this method on UIButton click event

-(void)shakescreen
{
    //Shake screen
    CGFloat t = 5.0;
    CGAffineTransform translateRight = CGAffineTransformTranslate(CGAffineTransformIdentity, t, t);
    CGAffineTransform translateLeft = CGAffineTransformTranslate(CGAffineTransformIdentity, -t, -t);

    self.view.transform = translateLeft;

    [UIView animateWithDuration:0.05 delay:0.0 options:UIViewAnimationOptionAutoreverse|UIViewAnimationOptionRepeat animations:^
    {
         [UIView setAnimationRepeatCount:2.0];
         self.view.transform = translateRight;
    } completion:^(BOOL finished)

      {
          if (finished) 
          {
             [UIView animateWithDuration:0.05 delay:0.0 options:UIViewAnimationOptionBeginFromCurrentState animations:^
          {
              self.view.transform = CGAffineTransformIdentity;
          } 
          completion:NULL];
      }
  }];
}

Hope this will help you :-)

> @imike answer in Swift 4.2

extension UIView {
func shake() {
    let animation = CAKeyframeAnimation(keyPath: "transform.translation.x")
    animation.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.linear)
    animation.duration = 0.6
    animation.values = [-20, 20, -20, 20, -10, 10, -5, 5, 0]
    self.layer.add(animation, forKey: "shake")
}}

C# Xamarin.iOS version of answer how to create UIView shake animation in iOS is below

        CAKeyFrameAnimation keyframeAnimation = CAKeyFrameAnimation.GetFromKeyPath(new NSString("transform.translation.x"));
        keyframeAnimation.TimingFunction = CAMediaTimingFunction.FromName(CAMediaTimingFunction.EaseInEaseOut);
        keyframeAnimation.Duration = 0.6f;
        keyframeAnimation.Values = new NSObject[]{ new NSNumber(-20f), new NSNumber(20f), new NSNumber(-20f), new NSNumber(20f), new NSNumber(-10f), new NSNumber(10f), new NSNumber(-5f), new NSNumber(5f), new NSNumber(0f) };
        shakyView.Layer.AddAnimation(keyframeAnimation, "shake");

Here's one that uses a damper function to decay the shake:

- (void)shake
{
    CAKeyframeAnimation* animation = [CAKeyframeAnimation animationWithKeyPath:@"position"];
    animation.duration = 0.5;
    animation.delegate = self;
    animation.fillMode = kCAFillModeForwards;
    animation.removedOnCompletion = YES;
    animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];

    NSMutableArray* values = [[NSMutableArray alloc] init];

    int steps = 100;
    double position = 0;
    float e = 2.71;

    for (int t = 0; t < steps; t++)
    {
        position = 10 * pow(e, -0.022 * t) * sin(0.12 * t);
        NSValue* value = [NSValue valueWithCGPoint:CGPointMake([self center].x - position, [self center].y)];
        DDLogInfo(@"Value: %@", value);
        [values addObject:value];
    }

    animation.values = values;
    [[self layer] addAnimation:animation forKey:@"position"];

}

I refactored @Matt Long code and made a category to UIView. Now it's much more reusable and easy to use.

@implementation UIView (Animation)

- (void)shakeViewWithOffest:(CGFloat)offset {
    CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"position.x"];
    [animation setDuration:0.05];
    [animation setRepeatCount:6];
    [animation setAutoreverses:YES];
    [animation setFromValue:@([self center].x-offset)];
    [animation setToValue:@([self center].x+offset)];
    
    [self.layer addAnimation:animation forKey:@"position.x"];
}

- (void)shake {
    [self shakeViewWithOffest:7.0f];
}
@end

Swift 3 implementation based on @Mihael-Isaev answer

private enum Axis: StringLiteralType {
    case x = "x"
    case y = "y"
}

extension UIView {
    private func shake(on axis: Axis) {
        let animation = CAKeyframeAnimation(keyPath: "transform.translation.\(axis.rawValue)")
        animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear)
        animation.duration = 0.6
        animation.values = [-20, 20, -20, 20, -10, 10, -5, 5, 0]
        layer.add(animation, forKey: "shake")
    }
    func shakeOnXAxis() {
        self.shake(on: .x)
    }
    func shakeOnYAxis() {
        self.shake(on: .y)
    }
}

Swift 4.0:

Based on the top answer but a refinement over the animation: This does not have the jumps at the start and end of animation.

    let midX = center.x
    let midY = center.y
    
    let rightAnim = CABasicAnimation(keyPath: #keyPath(CALayer.position))
    rightAnim.duration      = 0.07
    rightAnim.autoreverses  = true
    rightAnim.fromValue     = CGPoint(x: midX, y: midY)
    rightAnim.toValue       = CGPoint(x: midX + 9, y: midY)

    let leftAnim = CABasicAnimation(keyPath: #keyPath(CALayer.position))
    leftAnim.duration       = 0.07
    leftAnim.autoreverses   = true
    leftAnim.fromValue      = CGPoint(x: midX, y: midY)
    leftAnim.toValue        = CGPoint(x: midX - 9, y: midY)

    let group = CAAnimationGroup()
    group.duration      = leftAnim.duration + rightAnim.duration
    group.animations    = [rightAnim, leftAnim]
    group.repeatCount   = 3

    layer.add(group, forKey: #keyPath(CALayer.position))

You can try the following code:

+ (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"];

}
