CABasicAnimation back to its original position after it finishes its 1 cycle

Don't refer CABasicAnimation returns to the original position before the next animation and Objective-C - CABasicAnimation applying changes after animation? and CABasicAnimation rotate returns to original position ,I have tried.

The below code does:

bottom->top->goes left->back to its original position.
bottom->top->goes left->back to its original position.

I need:

bottom->top->goes left. bottom->top->goes left so on…

- (void)addUpDownAnimationForButton:(UILabel*)label {
    CABasicAnimation * bottomAnimation ;
    bottomAnimation =[CABasicAnimation animationWithKeyPath:@"transform.translation.y"];
    [bottomAnimation setValue:@"animation1" forKey:@"id"];
    bottomAnimation.delegate = self;
    [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:)];
    bottomAnimation.duration = 2.0;
    bottomAnimation.fromValue = [NSNumber numberWithFloat:13];
    bottomAnimation.toValue = [NSNumber numberWithFloat:-7];
    bottomAnimation.repeatCount = 0;
    bottomAnimation.fillMode = kCAFillModeForwards;
    bottomAnimation.removedOnCompletion = NO;
    [btnSpecialForListing.titleLabel.layer addAnimation:bottomAnimation forKey:@"transform.translation.y"];
}

- (void)animationDidStop:(CAAnimation *)theAnimation2 finished:(BOOL)flag {
    if([[theAnimation2 valueForKey:@"id"] isEqual:@"animation1"]) {
        CABasicAnimation *moveAnimation;
        moveAnimation=[CABasicAnimation animationWithKeyPath:@"transform.translation.x"];
        moveAnimation.duration=3.5;
        moveAnimation.repeatCount=0;
        moveAnimation.autoreverses=NO;
        moveAnimation.fromValue=[NSNumber numberWithFloat:0];
        moveAnimation.toValue=[NSNumber numberWithFloat:-400];
        moveAnimation.removedOnCompletion = NO;
        moveAnimation.fillMode = kCAFillModeRemoved;
        [btnSpecialForListing.titleLabel.layer addAnimation:moveAnimation forKey:@"transform.translation.x"];
    } 
}

Have you tried this? (Edited)

moveAnimation.fillMode = .forwards
moveAnimation.isRemovedOnCompletion = false

EDIT As far as I can see you can also use animateWithDuration which has a completion block. Example would be:

CGRect rect = btnSpecialForListing.titleLabel.frame;
[UIView animateWithDuration:2.0 animations:^{

 rect.origin.y = -7;
 btnSpecialForListing.titleLabel.frame = rect;

} completion:^(BOOL finished){

 [UIView animateWithDuration:3.5 animation:^{
 rect.origin.x = -400;
 btnSpecialForListing.titleLabel.frame = rect;
 }];

}];
