suppose you have to show some images inside an Array.

[yourScroll setContentSize CGSizeMake( [arrayImages count]*320 , 420)];
[yourScroll setPagingEnabled : YES];
int incX = 0 ;

for( int i = 0; i < [arrayImages count]; i++)
{
  UIImageView *imgView = [[UIImageView alloc]initWithFrame : CGRectMake(0,0,320,420)];
  UIView *myView = [UIView alloc]initWithFrame : CGRectMake (incX,0,320,420);
  imgView.image = [UIImage imageNamed:[NSString stringWithFormat:@"%@",[arrayImages objectAtIndex : i]]];
  [myView addSubView : imgView];  
  [yourScroll addSubView : myView];
   incX+= 320;
}

You must be doing something wrong. If you have paging enabled, it will automatically align to pages(where page size is size of scrollview frame). Maybe you are paging programatically somewhere(which is not needed if pagingEnabled is true).

Can't tell more without the code

For example:

- (IBAction)changePage:(id)sender 
{        
    NSInteger _currentPage = self.pageControl.currentPage;
    CGPoint offset = CGPointMake(_currentPage * self.scrollView.frame.size.width, 0);
    [self.scrollView setContentOffset:offset animated:YES];
    pageControlUsed = YES;
}
