title: Two UITableView in the same view
body: <p>I want to know if it's allowed to use Multiple <code>UItableView</code> in the same View (i don't see any thing in the <a href="https://developer.apple.com/ios/human-interface-guidelines/overview/design-principles/" rel="nofollow noreferrer">Apple's Human Interface Guidelines</a>) and if it's OK, How to load different <code>DataSource</code> in <code>viewDidLoad</code> for each <code>UITableView</code>?</p>
