I have UIViewController
with UINavigationBarDelegate
delegate and I set everything's programmatically and my app is multi language so I need RTL (Right to Left) support in every section like NavigationBar. I used this approach:
if MSGlobal.setting.language.direction == .L2R
{
navigationItem.setRightBarButtonItems(rightItems, animated: true)
}
else
{
navigationItem.setLeftBarButtonItems(rightItems, animated: true)
}
let stackCount = navigationController!.viewControllers.count
if stackCount == 1
{
let leftBtnItem:UIBarButtonItem = UIBarButtonItem(image: UIImage(named:"drawer"), landscapeImagePhone: UIImage(named:"drawer"), style: UIBarButtonItemStyle.Plain, target: self, action: "cb_drawerTapped:")
if MSGlobal.setting.language.direction == .L2R
{
navigationItem.setLeftBarButtonItem(leftBtnItem, animated: true)
}
else
{
navigationItem.setRightBarButtonItem(leftBtnItem, animated: true)
}
}
else
{
navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.Plain, target: self, action: "cb_back:")
}
Everything's work fine in LTR language like English, But in RTL language back button not shown. My result must be like this:
LTR: [ < Title [btn1...btnn]]
RTL: [[btnn...btn1] Title > ]
If your goal is to have right UIBarButtonItem
with back action , you can change it through Storyboard by changing Semantic
to Force-Right-to-Left
. or by code below:
inside your ViewController
viewDidLoad()
:
self.navigationController?.navigationBar.semanticContentAttribute = .forceRightToLeft
If You want to change navigation bar and the navigation controller flow to right to left direction you can use like:
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.navigationBar.semanticContentAttribute = .forceRightToLeft
}
But you should mention that it wont change Swipe Direction
, It only effect on navigationBar, If you want to change the Swipe Direction
then you can use:
self.navigationController?.view.semanticContentAttribute = .forceRightToLeft
If you want to do all of them in one line and change the whole app RTL use:
UIView.appearance().semanticContentAttribute = .forceRightToLeft
