How to stop UIBarButtonItem text from truncating?

Question

I have a UIBarButtonItem in a Navigation Bar with the text title "Save". When I transition to a fullscreen UIPopoverController and then dismiss it, the text in my UIBarButtonItem gets truncated to "S..e". For all other segues and views I have no problem when returning.

I've tried manually changing the width and setting "possibleTitles" to include long words but I can't stop the truncation.

I'm using a custom font if that makes a difference.

Answer 1

Try to init your UIBarButtonItem with a custom view.

[[UIBarButtonItem alloc] initWithCustomView:yourView];

Just make sure your custom view has the right frame (e.g. for an UILabel ,wide enough to not truncate its content). Things should work fine.

Answer 2

Perhaps helpful, but a UIBarButtonItem with a custom view (ex: UILabel) that is inserted into a UIToolbar can take on the intrinsic size of its contents as long as translatesAutoresizingMaskIntoConstraints is set to false. I believe this may work for UINavigationBar too:

private let barButtonLabel: UIBarButtonItem = {
    let label = UILabel(frame: .zero)
    label.translatesAutoresizingMaskIntoConstraints = false
    return UIBarButtonItem(customView: label)
}()
