Our app supports RTL language like Arabic, Persian.

After iOS 9 the navigation controller and tab bar controller behavior has been changed. I found only this link ios-9-disable-support-for-right-to-left-language for solve this problem

I write this code in my appDelegate and it works fine and navigation bar and tab bar set as LTR. 

if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"9.0")) {
    [[UINavigationBar appearance] setSemanticContentAttribute:UISemanticContentAttributeForceLeftToRight];
    [[UITabBar appearance] setSemanticContentAttribute:UISemanticContentAttributeForceLeftToRight];
}

But my problem is: I can't change interactive pop gesture Direction .

    @Fogmeister because it's has a bad style and not regular for UX . you can change Language and see Whatsapp ( they have handled this problem ) but telegram team leave this problem. Do u have any idea ? – Mo Farhand Oct 04 '15 at 10:44
  • Is that your opinion or is it something you have spoken to many rtl users about? Where I work we spent a long time interviewing our users. It really is something that rtl users want. – Fogmeister Oct 04 '15 at 10:45
  • @Fogmeister i'm agree with you , but in this case we need this and in Apple Docs you can see this : ~Flipping Cocoa Touch Views and Controls Programmatically` https://developer.apple.com/library/prerelease/ios/documentation/MacOSX/Conceptual/BPInternational/SupportingRight-To-LeftLanguages/SupportingRight-To-LeftLanguages.html – Mo Farhand Oct 04 '15 at 10:49

    Mohamad, that doc only describes ways to adapt controls to the new RTL UI in iOS 9, which is the opposite of what you are trying to do here. I would highly recommend not doing this; as more apps start linking against iOS 9, more apps will have the flipped UI by default if they support a RTL language. At the end of the day, it will be your app that will be inconsistent with the rest of the system. – wakachamo Oct 04 '15 at 12:34
  • @wakachamo thanks my Bro for your hint – Mo Farhand Oct 06 '15 at 06:32
  • I have the same issue, I just try to disable it and not find any other solution, if you found out please publish it, http://stackoverflow.com/a/32097310/3477974 – Soheil Novinfard Feb 27 '16 at 09:24
  • @SoheilNovinfard i recommend to you leave this behavior. because it's normal and all of apps in app store accept this behavior :) – Mo Farhand Feb 28 '16 at 09:49

I was struggling with same problem and finally found solution

you just need to set SemanticContentAttribute for navigationController.view

in the rootViewController's viewDidLoad:

[self.navigationController.view setSemanticContentAttribute:UISemanticContentAttributeForceLeftToRight];
[self.navigationController.navigationBar setSemanticContentAttribute:UISemanticContentAttributeForceLeftToRight];

In Swift 

navigationController?.view.semanticContentAttribute = .forceRightToLeft
navigationController?.navigationBar.semanticContentAttribute =  .forceRightToLeft

If your are creating custom pop up, two way you can handle this.

  1. Define a macro in .h file to detect whether it is RTL language or not in runtime.

    define IS_RTL [UIApplication sharedApplication].userInterfaceLayoutDirection == UIUserInterfaceLayoutDirectionRightToLeft

then create custom layout according if IS_RTL.Like

if (IS_RTL)
//Do Arabic Implementation
else
//Do other language implementation
  1. If you are creating UI from Storyboard, the set constraint to Lead or Trailing space and value of First Item will be Respect Language Direction

  • tnx for your answer , but unfortunately after i OS 9 we cant do it without `setSemanticContentAttribute` anyway , `Respect Language Direction` is good for our alignment but for our direction not work. conclusion : we respect to this behavior like many app to app store :) – Mo Farhand Dec 28 '15 at 07:19
