NavigationController Right to Left in iOS

Question

I am buiding a Right to Left navigation controller to support RTL Languages. After reading some posts in StackOverFlow Push ViewController from Right To Left with UINavigationCo

Answer 1

Considering that you're essentially hacking into the navigation controller, in order to keep the behavior consistent, you need to hack it some more.

Popping a navigation controller releases it from the memory, so you would probably need another array or stack containing popped controllers (pushed controllers from the users perspective, because as far as I see it, you're popping whenever you need to push, and pushing whenever you need to pop). In that array/stack, you would keep the controllers you need to come back to, pushing them into the array/stack just before you pop them.

I'll assume that the mutable array exists somewhere you can access it at all times, and call it otherNavigationController for the sake of simplicity:

DetailedViewController *DVC = [[DetailedViewController alloc]initWithNibName:@"DetailedViewController" bundle:nil];
NSMutableArray *vcs = [NSMutableArray arrayWithArray:self.navigationController.viewControllers];
[vcs insertObject:DVC atIndex:[vcs count]-1];
[self.navigationController setViewControllers:vcs animated:NO];
[otherNavigationController addObject:self];
[self.navigationController popViewControllerAnimated:YES];

As for the second part of your question, you would need to add custom back button because the default one wouldn't work for you. The custom button should on press push a view controller from the top of the aforementioned array/stack (pop it from the users perspective).

The code for the pop function would go something like this:

UIViewController *previousViewController = [otherNavigationController lastObject];
[otherNavigationController removeLastObject];
[self.navigationController pushViewController:previousViewController animated:YES];

Disclaimer: The code here is untried and untested and I'm not even sure this would work, but it should get you on your way. Good luck!
