Getting the current page

There is no UIScrollView property for the current page. You can calculate it with:

int page = scrollView.contentOffset.x / scrollView.frame.size.width;

If you want to round up or down to the nearest page, use:

CGFloat width = scrollView.frame.size.width;NSInteger page = (scrollView.contentOffset.x + (0.5f * width)) / width;

I pretty recommend you to use this code

int indexOfPage = scrollView.contentOffset.x / scrollView.frame.size.width;

but if you use this code your view doesn't need to be exactly on the page that indexOfPage gives you.It because I also recommend you to use this code only in this method

-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{}

which is called when your scrollView finishes scrolling and to have number of your page really sharp

I recommend you to set your scrollView to paged enabled with this code

[scrollView setPagingEnabled:YES];

So finally it should look like that way

-(void) methodWhereYouSetYourScrollView{   //set scrollView   [scrollView setPagingEnabled:YES];   scrollView.delegate = self;}-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{   int indexOfPage = scrollView.contentOffset.x / scrollView.frame.size.width;   //your stuff with index}

In swift I would do it in extension:

extension UIScrollView {    var currentPage:Int{        return Int((self.contentOffset.x+(0.5*self.frame.size.width))/self.frame.width)+1    }}

Then just call:

scrollView.currentPage
