Everything works perfectly before iOS 9.
However, when the app is running on iOS 9, nothing happens when back button is tapped so I am not able to go back as well as it keeps greyed out.
Also, I am not able to segue to the next view after the first segue.
For example,
HomePage -> tap a button to segue to view 1 -> Segued to View 1
-> tap on a button to segue to view 2 -> nothing happens
I uses the code below to perform segue,
UIViewController *push =
[self.storyboard instantiateViewControllerWithIdentifier:@"storyboard_id"];
[self.navigationController pushViewController:push animated:YES];
This issue only happens at iPhone
but the app works flawlessly when running on a simulator.
Thank you for your help.
