can any one please tell me how to scroll on touching the buttton

Answer 1

If i have understood correctly, you want to scroll the scrollView by tapping a UIButton.
UIScrollView has a method
scrollRectToVisible:animated: to scroll programmatically your scrollView.

You can try this:

-(IBAction)switchToPG2{
    CGRect frame = self.scrollView.frame;
    frame.origin.x = frame.size.width * 1;//or the index of the page that you want
    self.pageControl.currentPage=1;
    frame.origin.y = 0;
    [self.scrollView scrollRectToVisible:frame animated:YES];
}

Hope this helps.
