How I Learned to Quit Worrying and Love Storyboards

For a long time, I've been convinced that the only way to build iOS applications. Recently I've made the switch to use Storyboards for a project. At CocoaHeads May in Durham, NC I shared some of the things we've been doing to stay productive while working with something that was new to us.

1. How I Learned to Stop Worrying and Love the Storyboard Josh Johnson · @jnjosh · jnjosh.com
2. I spent a lot of time hating on Storyboards
3. So, on any given NSCoder Night…
4. “Storyboards are awesome!” 1 Abbie
5. “That's crazy, I'll just write the code!" 1 Me
6. “No really, you should look again…” 1 Abbie
7. “Why do people hate writing code?” 1 Me
8. So, then we get a client project that uses Storyboards
9. I cry
10. But we decide to keep the Storyboards
11. I cry, again
12. Spoiler: It hasn't been so bad…
13. A partial list of things we've done to work with Storyboards.
14. Use Multiple Storyboards
16. Crossing to another Storyboard UIViewController *mainViewController = [[UIStoryboard storyboardWithName:@"MainWorkflow" bundle:nil] instantiateInitialViewController]; [self presentViewController:mainViewController animated:YES completion:nil];
17. Dynamic Prepare For Seque
18. This can get ugly… - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { NSString *identifier = segue.identifier; if ([identifier isEqualToString:@"FriendsToFacebookFriends"]) { // … } else if ([identifier isEqualToString:@"FriendsToTwitterFriends"]) { // … } else if ([identifier isEqualToString:@"FriendsToContacts"]) { // … } }
19. Dynamic Method Dispatch! - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { [self twt_prepareForSegue:segue sender:sender]; } /// - (void)twt_prepareForFriendsToFacebookFriendsSegue:(UIStoryboardSegue *)segue sender:(id)sender; - (void)twt_prepareForFriendsToTwitterFriendsSegue:(UIStoryboardSegue *)segue sender:(id)sender; - (void)twt_prepareForFriendsToContactsSegue:(UIStoryboardSegue *)segue sender:(id)sender;
20. UIViewController+TWTPrepareForSegue.h https://github.com/twotoasters/Toast pod 'TWTToast/UIKit/PrepareForSegue', '~> 0.8'
21. Multiple Segues to a Single View
23. Manually Performing the Segue - (void)itemSelected:(TWTItem *)item { if ([self shouldPerformSegueWithIdentifier:item.segueIdentifier sender:self]) { [self performSegueWithIdentifier:item.segueIdentifier sender:self]; } }
24. Remember Dynamic Method Dispatch? - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { [self twt_prepareForSegue:segue sender:sender]; } /// - (void)twt_prepareForFriendsToFacebookFriendsSegue:(UIStoryboardSegue *)segue sender:(id)sender; - (void)twt_prepareForFriendsToTwitterFriendsSegue:(UIStoryboardSegue *)segue sender:(id)sender; - (void)twt_prepareForFriendsToContactsSegue:(UIStoryboardSegue *)segue sender:(id)sender;
25. Naming Conventions
26. Name your Segue Identifiers consistently static NSString *const kInviteSourceToContactsSegueIdentifier = @"InviteSourceToContacts"; static NSString *const kInviteSourceToFacebookSegueIdentifier = @"InviteSourceToFacebook"; static NSString *const kInviteSourceToTwitterSegueIdentifier = @"InviteSourceToTwitter"; /// - (void)twt_prepareForInviteSourceToContactsSegue:(UIStoryboardSegue *)segue sender:(id)sender;
27. Nib-backed Views
28. @protocol TWTNibBackedView <NSObject> + (UINib *)nib; @end /// In TWTTestCollectionViewCell + (UINib *)nib { return [UINib nibWithNibName:NSStringFromClass(self) bundle:nil]; } /// In TWTTestCollectionViewController -viewDidLoad [collectionView registerNib:[TWTTestCollectionViewCell nib] forCellWithReuseIdentifier:kCellIdentifier];
29. So, It hasn't been so bad
30. Keep an open mind
