Answer 1

You can do something like this,
- (void)loadNextController
{
//put if statement here to check whether it is page object something like,
//have aasume that your first page number is 0. so take count - 1 in if
if(pageControl.currentPage == (pageControllMutableImageArray.count - 1)){
//start from initial. set current page = 0 and contentoffset of first page
}
else {
// your code for next page may be like,
pageControl.currentPage = (pageControl.currentPage+1)%self->pageControllMutableImageArray.count;
[ScrollViewPage setContentOffset:CGPointMake(pageControl.currentPage * self.view.bounds.size.width, 0) animated:YES];
}
}
Hope this will help. :)
Update 2 :
you can set content offset of first page like:
CGPoint newOffset = CGPointMake(0, 0);
[self.standardScrollView setContentOffset:newOffset animated:YES];
