I have read the apple documentation concerning UIScrollView but cannot reach to a clear idea about setting the scrollview with paging enabled scrolling direction starts from Left to RIGHT to suite ARABIC content ... any ideas please ??
I solved the problem by using UISlider by setting the slider to the last page of my scrollview in viewdidload
CGPoint pnt = CGPointMake(19 * self.scrollView.frame.size.width , 0) ;
[self.scrollView setContentOffset:pnt animated:YES];
CGFloat pageWidth = self.scrollView.frame.size.width;
NSInteger page = (NSInteger)floor((self.scrollView.contentOffset.x * 2.0f + pageWidth) / (pageWidth * 2.0f));
[slider setValue:page];
Now I can scroll by tap and scroll the appropriate direction for arabic content :)
note : 19 is the number of pages in scrollview which equals to no of images - 1 .
