try:
scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height])];
scroll.contentSize = CGSizeMake(5000, rowHeight*[lstMatches count]);
[self.view addSubview:scroll];
PS: Change the contentSize.width
of 5000 to something that suits your needs
