Animate center point of a view along a quadratic curve - objective-c

Question

I have an app that stores user events in history. The events are added on one controller and are displayed in a controller within a different tab.
I would like to add a visual confirmation that an event has been recorded when a user taps "save button". I'm thinking of animating an interface element to move towards a tab bar controller that is responsible for showing records to the user.
In order to do so, I'm thinking of animating the center point of one of my interface elements. I know how to animate the center point, but it does so in a straight line. How can I animate the center point in a more "curved" way? Is there some way to accomplish this?
CGPoint center = self.ratingReticle.center;
[UIView animateWithDuration:0.6 delay:0 options:UIViewAnimationCurveEaseIn animations:^{
//move the element offscreen
self.ratingReticle.center = CGPointMake(260,500);
} completion:^(BOOL finished) {
//hide the interace element once it is offscreen
self.ratingReticle.alpha = 0;
//restore the position of the interface element
self.ratingReticle.center = center;
[ UIView animateWithDuration:0.4 animations:^{
//fade the element back at the original position
self.ratingReticle.alpha = 1;
} completion:^(BOOL finished) {
}];
}];

Answer 1

You could that using Core Animation to move your object along a Bezier curve using CAKeyFrameAnimation.
-(void)animate
{
CAKeyframeAnimation *posAnim = [CAKeyframeAnimation animationWithKeyPath:#"position"];
posAnim.path = [self bezierPath];
[image.layer addAnimation:posAnim forKey:#"posAnim"];
}
where bezierPath returns a CGPathRef that suits your case.
