带有长文本的标题视图会推动Swift 4 iOS 11导航栏后退按钮

Question

For a long title on iOS 11, the back button arrow and text are not showing.

I searched for a solution and the closest I got was navigation bar rightbaritem image-button bug iOS 11

It looks like this

When it should look like this for long titles also

My problem though is that I don't have an explicit button added, instead the titleview pushes the "< Back" default leftBarButtonItem that I create:

navigationItem.backBarButtonItem = UIBarButtonItem(title: NSLocalizedString("Back", comment: ""), style: .plain, target: nil, action: nil)

How can I add constraints to that (UIBarButtonItem)?

Answer 1

最后，我降低了titleviews文本的抗压缩性，因此长条按钮项具有更高的优先级，一切都准备就绪。
