animateWithDuration not working - objective-c

Question

I'm trying to animate a view with some buttons and controllers for my main view into the screen from the right side of the screen. The problem is it doesn't animate, it just goes directly to the finished state.
This is my code:
UIStoryboard* storyBoard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
options = [storyBoard instantiateViewControllerWithIdentifier:#"OptionsView"];
options.delegate = self;
[self.view addSubview:options.view];
options.view.center = CGPointMake(floor(total_width+options.view.frame.size.width/2)+10, floor(total_height/2));
[UIView animateWithDuration:0.5
delay:0.0
options: UIViewAnimationOptionCurveEaseOut
animations:^{
options.view.center = CGPointMake(floor(total_width-options.view.frame.size.width/2)+10, floor(total_height/2));
}
completion:^(BOOL finished){
NSLog(#"Done!");
}];
EDIT
To make things more strange, if I put this animation inside the completion block of another animation then this one works, but not the new one.
UIButton* boton = (UIButton*) sender;
[UIView animateWithDuration:5.0
delay:0.0
options: UIViewAnimationOptionCurveLinear
animations:^{
boton.alpha = 0.0;
//Jumps directly to 0, animation doesn't work
}
completion:^(BOOL finished){
[UIView animateWithDuration:0.5
delay:0.0
options: UIViewAnimationOptionCurveEaseInOut
animations:^{
options.view.center = CGPointMake(floor(total_width-options.view.frame.size.width/2)+10, floor(total_height/2));
//It works now, but it doesn't take 5 seconds to start, it starts right away
}
completion:^(BOOL finished){
NSLog(#"Done!");
}];
}];

Answer 1

The line before the animateWithDuration:... call directly assigns the center to the same value that you're animating to. Either remove that or assign the initial center value there. An animation that has the same start and end values obviously has no effect.
