how to put shake animation on uiimageview?

Question

I've been trying to implement this but couldn't find any code that could shake it like iPhone app shakes while 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 by the following code, you have define the rotation angle 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 this:

- (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"];
}
