Set number of pages in the pageControl

NSUInteger numberOfCells = 10;
_pageControl.numberOfPages = numberOfCells;

Implement scrollView delegate method

 -(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{
 // Suppose your collectionview cell width is equal to your screen size
 CGFloat collectionViewCellWidth = self.view.frame.size.width;     
_pageControl.currentPage = (scrollView.contentOffset.x / collectionViewCellWidth);
}

Implement the scroll view's delegate method as follows:-

Say collectionViewTestimonial : Name(IBOutlet) of your collection view, pageControlTestimonial: Name of page control

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    CGFloat pageWidth = collectionViewTestimonial.frame.size.width;
    pageControlTestimonial.currentPage = collectionViewTestimonial.contentOffset.x / pageWidth;
}

Try like this :

-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{
 // Suppose your collectionview cell width is equal to your screen size
 CGFloat collectionViewCellWidth = self.view.frame.size.width;     
_pageControl.currentPage = (scrollView.contentOffset.x / collectionViewCellWidth);
}
