Handling State Restoration for UITabBarController in Objective-C
I've looked through the documentation and I'm still confused about I've spent hours debugging this and I'm working with an scenario with state restoration for a `UITabBarController` in my Objective-C application. When I enable state restoration, I notice that even though the view controllers are being restored, the selected tab is not being set correctly, and I end up seeing the first tab instead of the one that was active before termination. I've properly set up the restoration identifiers for both the tab bar controller and its child view controllers. Here’s a snippet of what I have: ```objective-c - (void)viewDidLoad { [super viewDidLoad]; self.restorationIdentifier = @"MainTabBarController"; UIViewController *firstVC = [[FirstViewController alloc] init]; firstVC.restorationIdentifier = @"FirstVC"; UIViewController *secondVC = [[SecondViewController alloc] init]; secondVC.restorationIdentifier = @"SecondVC"; self.viewControllers = @[firstVC, secondVC]; } - (void)encodeRestorableStateWithCoder:(NSCoder *)coder { [super encodeRestorableStateWithCoder:coder]; [coder encodeInteger:self.selectedIndex forKey:@"selectedIndex"]; } - (void)decodeRestorableStateWithCoder:(NSCoder *)coder { [super decodeRestorableStateWithCoder:coder]; NSInteger index = [coder decodeIntegerForKey:@"selectedIndex"]; self.selectedIndex = index; } ``` My `encodeRestorableStateWithCoder:` and `decodeRestorableStateWithCoder:` methods seem straightforward, and I double-checked that the restoration identifiers match. However, after restoring the state, the selected tab remains at index 0. I am testing on iOS 15 and using Xcode 13.1. Is there something I might be missing, or a best practice for managing tab bar restoration that I should be aware of? Any guidance or debugging tips would be greatly appreciated! My development environment is Ubuntu. What's the best practice here? I'm coming from a different tech stack and learning Objective-C. Could this be a known issue? My development environment is Ubuntu 20.04. Any advice would be much appreciated. Thanks for any help you can provide!
