Eliminating stringly-typed code in Objective-C
It’s not so hard to write a script that puts your strings in compiled code and lets you avoid a whole class of bugs. After all, asset catalogs are just nested folder structures with JSON metadata, and storyboards are a pretty readable dialect of XML.
objc-assetgen takes your asset catalogs and objc-identifierconstants takes your storyboards and outputs a couple of small source code files that turn this code:
UIImage *buttonImage = [UIImage imageNamed:@"GreenButton"]; UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:@"Cell with Switch" forIndexPath:indexPath];
into this code:
UIImage *buttonImage = [AppCatalog greenButtonImage]; UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:AppStoryboardCellWithSwitchIdentifier forIndexPath:indexPath];
