I'm trying to do an animation where I move one CGPoint from one view to another, I want to find the coordinates where the point is going to be in reference to the first so I can do the animation. So let's say I have a point (24,15) in view2 and I'd like to animate it to view1, I still want to keep the value of the point within the new view as I'm adding the point as a subview of the new view, but for the animation I need to know the value of where the point would be so I can do a tween. Please refer to this graph: Now this is what I'm trying to do: customObject *lastAction = [undoStack pop]; customDotView *aDot = lastAction.dot; CGPoint oldPoint = aDot.center; CGPoint newPoint = lastAction.point; newPoint = [lastAction.view convertPoint:newPoint toView:aDot.superview]; CABasicAnimation *anim4 = [CABasicAnimation animationWithKeyPath:@"position"]; anim4.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]; anim4.fromValue = [NSValue valueWithCGPoint:CGPointMake(oldPoint.x, oldPoint.y )]; anim4.toValue = [NSValue valueWithCGPoint:CGPointMake( newPoint.x, newPoint.y )]; anim4.repeatCount = 0; anim4.duration = 0.1; [aDot.layer addAnimation:anim4 forKey:@"position"]; [aDot removeFromSuperview]; [lastAction.view addSubview:aDot]; [lastAction.view bringSubviewToFront:aDot]; aDot.center = newPoint; Any ideas?
