iCarousel scroll

How to scroll in a specific item or index, for example: I set an NSInteger on another UIView then pass it to my iCarousel.In my other UIView I set the NSInteger like this:

[[NSUserDefaults standardUserDefaults] setInteger:button.tag                                           forKey:@"integer"];[[NSUserDefaults standardUserDefaults] synchronize];

When scrolling I use this :

[carousel scrollByNumberOfItems:-35 duration:10.7550f];

how to pass the integer to the carousel, to make it scroll then stop it to that specific item or index.
