Probably it is just a question of proper syntax.
I use the animateWithDuration:delay:options:animations:completion: UIView method. 
The options: is the problematic part here: when I assign only one option (for example UIViewAnimationOptionCurveEaseInOut) everything works fine.   
What if I want to assign multiple options to the same animation? How can I do that?
I have tried the following code, but the options: part turned out to be completely ignored:
>   [UIView animateWithDuration:DURATION
>                         delay:DELAY
>                       options:(UIViewAnimationOptionAllowUserInteraction,
>                                UIViewAnimationOptionCurveEaseInOut)
>                    animations: ^{/*animations here*/}
>                    completion: ^(BOOL finished){/*actions on complete*/}];
It was just a try and it didn't work. Which syntax should I use here?
Thanks for any help in advance.
