How iOS UITableView under NavigationBar?

Question

I have set

NavigationController.NavigationBar.Translucent = true;

Then add table and set frame to RootView Frame, and:

    public override void ViewDidLayoutSubviews()
        {
            base.ViewDidLayoutSubviews();
            float y = this.TopLayoutGuide.Length;
            table.ContentInset = new UIEdgeInsets (y, 0, 0, 0);
        }

But, I Have table Scroll Bar under NavigationBar (I use monotouch):

Answer 1

I solved task with this simple code:

table.ScrollIndicatorInsets = new UIEdgeInsets(64, 0, 0, 0);

Answer 2

Most of the time, solutions that introduce a magic constant doesn't scale, for example if the next iPhone introduces a different navigation bar height we'll have to update our code.

Fortunately, Apple provided us cleaner ways of overcoming this issue, for example topLayoutGuide:

The topLayoutGuide property comes into play when a view controller is frontmost onscreen. It indicates the highest vertical extent for content that you don't want to appear behind a translucent or transparent UIKit bar (such as a status or navigation bar)

Programmatically you can achieve with the following code snippet (the same can be achieved via IB too):

override func viewDidLoad() {
  super.viewDidLoad()

  automaticallyAdjustsScrollViewInsets = false
  tableView.translatesAutoresizingMaskIntoConstraints = false
  NSLayoutConstraint.activate([
    tableView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
    tableView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
    tableView.topAnchor.constraint(equalTo: 
       topLayoutGuide.bottomAnchor),
    tableView.bottomAnchor.constraint(equalTo: view.bottomAnchor)
  ])
}

Note: topLayoutGuide is deprecated in iOS 11, we should use the safeAreaLayoutGuide property of UIView instead.

Just put

navigationBar.translucent = NO; you problem will solve :)

Other option is,,

Put following code.

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    if([self respondsToSelector:@selector(edgesForExtendedLayout)])
        [self setEdgesForExtendedLayout:UIRectEdgeBottom];
}

Another option is ..

Why does UIViewController extend under UINavigationBar, while UITableViewController doesn't?

Answer 4

Try this:

    if([self respondsToSelector:@selector(edgesForExtendedLayout)])
    {
       self.edgesForExtendedLayout = UIRectEdgeNone;
       self.automaticallyAdjustsScrollViewInsets = NO;
    }

This worked for me

let yOffset = UIApplication.shared.statusBarFrame.height + self.navigationController!.navigationBar.frame.size.height
tableView.contentInset = UIEdgeInsetsMake(yOffset, 0, 0, 0)
