well, maybe this is not possible, but if your goal is simply to let users know this scrollable view, you can just let them see it when you load your web pages, forcing webContent to scroll up from position.y + 100 to Up. you will get the UIScrollView used by your UIWebView and scroll it ...
in your UIViewController just add this:
- (void)webViewDidFinishLoad:(UIWebView *)wwwebView {
UIScrollView *myUIWebScrollView = (UIScrollView*)[wwwebView.subviews objectAtIndex:0];
[myUIWebScrollView setContentOffset:CGPointMake(0, 100) animated:NO];
[self performSelector:@selector(scrollUp:) withObject:wwwebView afterDelay:0.4];
}
- (void)scrollUp:(UIWebView*)aWebView{
UIScrollView *myUIWebScrollView = (UIScrollView*)[aWebView.subviews objectAtIndex:0];
[myUIWebScrollView setContentOffset:CGPointMake(0, 0) animated:YES];
}
UIViewController UIWebViewDelegate, .h:
@interface yourWebViewController : UIViewController <UIWebViewDelegate> {
}
- (void)scrollUp:(UIWebView*)aWebView;
