UISplitViewController displayModeButtonItem()

Question

Does someone know a way to change the text (and appearance?) of the button returned from the UISplitViewController delegate:

func displayModeButtonItem() -> UIBarButtonItem?

Answer 1

I resolved it for myself in such way:

UIBarButtonItem(image: UIImage(named:"home"),
            landscapeImagePhone: UIImage(named:"home"),
            style: UIBarButtonItemStyle.Plain,
            target: splitViewController.displayModeButtonItem().target,
            action: splitViewController.displayModeButtonItem().action)

I use this in AppDelegate instead of splitViewController.displayModeButtonItem() and it works fine for me.

Answer 2

I made a combination of josh's and voluntas88's solutions on my solution.

First you need to use the UISplitViewControllerDelegate method func targetDisplayModeForActionInSplitViewController(_ svc: UISplitViewController) -> UISplitViewControllerDisplayMode and then add a customized UIBarButtonItem. Here is my solution:

func targetDisplayModeForActionInSplitViewController(svc: UISplitViewController) -> UISplitViewControllerDisplayMode {
        if svc.displayMode == UISplitViewControllerDisplayMode.PrimaryHidden || svc.displayMode == UISplitViewControllerDisplayMode.PrimaryOverlay {
            self.navigationItem.leftBarButtonItem = UIBarButtonItem(image: UIImage(named:"menu.png"),
                landscapeImagePhone: UIImage(named:"menu.png"),
                style: UIBarButtonItemStyle.Plain,
                target: self.splitViewController!.displayModeButtonItem().target,
                action: self.splitViewController!.displayModeButtonItem().action)
        }else {
// disable button on landscape
            if UIApplication.sharedApplication().statusBarOrientation == UIInterfaceOrientation.LandscapeLeft || UIApplication.sharedApplication().statusBarOrientation == UIInterfaceOrientation.LandscapeRight {
                self.navigationItem.leftBarButtonItem?.enabled = false
            }
        }
        return UISplitViewControllerDisplayMode.Automatic
    }
