UIButton and Labels in Navigation Bar Title View in Storyboard

Question

I have added a couple labels and an image to my navigation title bar. That all works great. But I want to cover all of it with a UIButton, but I can't get the UIButton to register any taps.

Here's what my view hierarchy looks like:

User interaction is enabled on everything, and I have an IBAction connected to the Button like this:

@IBAction func tapProjectEdit(_ sender: UIButton) {
  print("This never fires. :(")
}

Am I not allowed to have a UIButton in the navigation bar? Is there another way to pull this off?

Have you tried to add a UITapGestureRecognizer on titleView programmatically (instead of button) ? — arturdev, Jul 31 '18 at 18:56
That's a good idea. I just tried it and it still doesn't register any taps. — Clifton Labrum, Jul 31 '18 at 19:05
If I set the view like this: `self.navigationItem.titleView = buttonProjectEdit` the taps work (both the `IBAction` and the `UITapGestureRecognizer`), but then it removes my labels and only the button shows up. — Clifton Labrum, Jul 31 '18 at 19:08
Remove that button at all , and add the gestureRecognizer to self.navigationItem.titleView. And do that in viewWillAppear method — arturdev, Jul 31 '18 at 19:16
Thanks for the idea, though I just tried that and it didn't work. I also tried creating an `IBOutlet` from **View** and then setting `self.navigationItem.titleView = view` and adding the gesture recognizer, but that didn't work either. — Clifton Labrum, Jul 31 '18 at 20:12

I finally figured this out. I had a suspicion that the UIButton (and everything else in the View) didn't have an actual size since navigation subviews always act a little funny.

So I subclassed UIView, set that class to the View, and added this:

class FancyTitleView: UIView{
  override var intrinsicContentSize: CGSize {
    return UILayoutFittingExpandedSize
  }
}

Now it's working with a regular IBAction (no gesture recognizer required).

Yes, it worked in my case too. `https://stackoverflow.com/questions/46461350/custom-titleview-of-navigationitem-is-not-getting-tapped-on-ios-11/63241514#63241514` – Anil Gupta Aug 04 '20 at 07:27
