iOS 11 prefersLargeTitles not updating until scroll

Question

I implemented a basic UIViewController with a UITableView that\'s wrapped in a UINavigationController. I set prefersLargeTitles to true:

override fu         


        

Answer 1

Modifying the contentInset of the tableView with top:1 will force the NavigationBar to expand and display the large titles.

Obj-C

-(void) viewWillAppear:(BOOL)animated {
    if (@available(iOS 11.0, *)) {
        tableView.contentInset = UIEdgeInsetsMake(1, 0, 0, 0);
    }
}

Swift

override func viewWillAppear(_ animated: Bool) {
    if #available(iOS 11.0, *) {
        tableView.contentInset = UIEdgeInsetsMake(1, 0, 0, 0)
    }
}

Note: If you have a tableView.reloadData() in your viewWillAppear make sure to call it after editing the contentInset
