prefersLargeTitles doesn't work with programmatic layout

Question

I'm trying to add a table view programmatically, but large title doesn't show.

Here is my code:

self.view.addSubview(module.tableView)

module.view.translatesAutoresizingMaskIntoConstraints = false

if #available(iOS 11.0, *) {
    NSLayoutConstraint.activate([
        module.view.topAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.topAnchor, constant: 0),
        module.view.bottomAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.bottomAnchor, constant: 0),
        module.view.leadingAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.leadingAnchor, constant: 0),
        module.view.trailingAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.trailingAnchor, constant: 0)
    ])
}

Note: large titles enabled in view controller

if #available(iOS 11.0, *) {
    navigationController?.navigationBar.prefersLargeTitles = true
    navigationItem.largeTitleDisplayMode = .always
}

Maybe it's important: I'm trying to add a table as a child view controller. My child controller is a UITableViewController. And if I add child view in viewDidLoad() large title shows but doesn't scroll.

Here is the link to file where I'm adding my child module. Detail code you can see in question or here in addChild(module:) method.

Let me know how to fix this bug please.

Answer 1

I'm using a programmatic layout and ran into a similar issue. I found the solution here: https://stackoverflow.com/a/46692583/131378 . In viewDidLoad() I had to toggle the largeTitleDisplayMode off and on again. That was the correct combination that got the large titles working with scrolling:

self.navigationItem.largeTitleDisplayMode = .never
self.navigationItem.largeTitleDisplayMode = .always

Answer 2

Enable large titles in viewDidLoad method of the view controller where you're configuring the table view.

if #available(iOS 11, *) {
    self.navigationController?.navigationBar.prefersLargeTitles = true
}

Answer 3

Update your iOS Deployment Target to 11.0 or higher. Currently, it's at 10.3 . That's why you don't see the large titles.

Answer 4

You have to click your main Navigation Controller on Navigation Bar and then select "Prefers Large Titles" in your Attribute Inspector.
