How to put shake animation on uiimageview?

Question

I tried to implement this, but could not find code that could shake it, like the iPhone app shakes when deleting them!

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"]; 

Answer 1

you can achieve this with the following code, you determine the angle of rotation from and to.

 CABasicAnimation* anim = [CABasicAnimation animationWithKeyPath:@"transform.rotation"]; [anim setToValue:[NSNumber numberWithFloat:0.0f]]; [anim setFromValue:[NSNumber numberWithDouble:M_PI/16]]; // rotation angle [anim setDuration:0.1]; [anim setRepeatCount:NSUIntegerMax]; [anim setAutoreverses:YES]; [[imageView layer] addAnimation:anim forKey:@"iconShake"]; 

Answer 2

try the following:

 - (void)animateImage { CAKeyframeAnimation* animation = [CAKeyframeAnimation animationWithKeyPath:@"transform"]; CGFloat wobbleAngle = 0.06f; NSValue* valLeft = [NSValue valueWithCATransform3D:CATransform3DMakeRotation(wobbleAngle, 0.0f, 0.0f, 1.0f)]; NSValue* valRight = [NSValue valueWithCATransform3D:CATransform3DMakeRotation(-wobbleAngle, 0.0f, 0.0f, 1.0f)]; animation.values = [NSArray arrayWithObjects:valLeft, valRight, nil]; animation.autoreverses = YES; animation.duration = 0.125; animation.repeatCount = HUGE_VALF; [[lockView layer] addAnimation:animation forKey:@"shakeAnimation"]; }
