hi again there !

i just want to ask how can i move a UIView with a translation.
i want that my view do a translation from the point (0,0) to (0,100) and to (0,100) back to (0,0). i can move the UIView from (0,0) to (0,100) but when i configure the reverse translation that does'nt work ...

Code: 
CABasicAnimation *theAnimation; 
	
	theAnimation=[CABasicAnimation animationWithKeyPath:@"position"]; 
	theAnimation.duration=1; 
	theAnimation.repeatCount=1; 
	theAnimation.autoreverses=NO;
	[effet.layer addAnimation:theAnimation forKey:@"animateposition"];
	effet.layer.frame = CGRectMake(0,100,20,20);

theAnimation=[CABasicAnimation animationWithKeyPath:@"position"]; 
	theAnimation.duration=1; 
	theAnimation.repeatCount=1; 
	theAnimation.autoreverses=NO;
	[effet.layer addAnimation:theAnimation forKey:@"animateposition"];
	effet.layer.frame = CGRectMake(0,0,20,20);

any solution to perform this?
