Keep the End Position of Animation - objective-c

Question

I tried everything, but everytime its the same problem:
i want to move a button for y = 276. when the animation ends, my buttons jumps back to the startposition, but i want that the endanimationposition is the new position, and the button has to stay there, until a new animation is called.
tried with
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
CGPoint p = _cell00.center;
p.x += 100;
_cell00.center = p;
[UIView commitAnimations];
[UIView beginAnimations:nil context:nil];
same issue like
[UIView animateWithDuration:1.0 animations:^{
_cell00.frame = CGRectOffset(_cell00.frame, 0, 20);
}];
or
[UIView animateWithDuration:0.5 animations:^{
_cell00.center = CGPointMake(0, 20.0);
}];
EDIT:
I call this Animation with my Button called statisticsBUttonPressed.
- (IBAction)statisticsButtonPressed:(id)sender {
if (statOrGame == 0) {
statOrGame = 1;
}else {
statOrGame = 0;
}
NSLog(#"statOrGame? %d", statOrGame);
[self animateView:(UIButton *)sender];
}
-(void) animateView:(UIButton *)sender {
sender.userInteractionEnabled = NO;
if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone)
{ // The iOS device = iPhone or iPod Touch
NSLog(#"IS IPHONE 5");
CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size;
if (iOSDeviceScreenSize.height == 568)
{
if (statOrGame) {
[UIView animateWithDuration:1.0 animations:^{
_cell00.frame = CGRectOffset(_cell00.frame, 0, 20);
}];
}
}
}
}

The problem is that you're using auto layout. You can't (just) change the frame of a view that is positioned by auto layout, because what positions the view is its constraints. You need to change the constraints. You can do this at the end of the animation, or you can simply animate the change of constraints.
