Button's frame is not changing - ios

Question

I have a UIButton at the position x=0.0. Now when I am pressing that button the button is shifting and goes to a position at x=131.0. Now when I am pressing that again it should come back to x=0.0 position. But its not coming. It is staying at the position x=131.0.
This is the code I have written
- (IBAction)showMenuViewButton:(id)sender {
_horizontalConstraintsOfColorViewToMainView.constant = 0.0;
_buttonOfColorViewHoriozontalLeadingConstraints.constant = 131.0;
counter=counter+1;
if (counter%2 !=0) {
[UIView animateWithDuration:0.4
animations:^
{
_menuView.hidden = NO;
_menuView.frame = CGRectMake(0.0, _menuView.frame.origin.y, _menuView.frame.size.width, _menuView.frame.size.height);
_showMenuViewButton.frame = CGRectMake(_showMenuViewButton.frame.origin.x+_menuView.frame.size.width+_showMenuViewButton.frame.size.width,_showMenuViewButton.frame.origin.y, _showMenuViewButton.frame.size.width, _showMenuViewButton.frame.size.width);
}];
}
else{
[UIView animateWithDuration:0.4
animations:^
{
_menuView.hidden = NO;
_menuView.frame = CGRectMake(-102.0, _menuView.frame.origin.y, _menuView.frame.size.width, _menuView.frame.size.height);
_showMenuViewButton.frame = CGRectMake(0.0,_showMenuViewButton.frame.origin.y, _showMenuViewButton.frame.size.width, _showMenuViewButton.frame.size.width);
}];
}
}

- (IBAction)clickButton:(id)sender {
if (!isChangedPlace) {
isChangedPlace = true;
[UIView animateWithDuration:1.0
animations:^{
btn.frame = CGRectMake(btn.frame.origin.x, btn.frame.origin.y+100, btn.frame.size.width, btn.frame.size[self.height);view layoutIfNeeded];
}];
}
else
{
isChangedPlace = false;
[UIView animateWithDuration:1.0
animations:^{
btn.frame = CGRectMake(btn.frame.origin.x, btn.frame.origin.y-100, btn.frame.size[self.width,view btn.frame.size.height);layoutIfNeeded];
}];
}

I have set Y constraint using IBOutlet and change that value as follow.
- (IBAction)clickButton:(id)sender {
if (!isChangedPlace) {
isChangedPlace = true;
buttonYPointConstraint.constant += 50;
}

{
isChangedPlace = false;
buttonYPointConstraint.constant -= 50;
}
[UIView animateWithDuration:1.0 animations:^{
[self.view layoutIfNeeded];
}];
}
