model class with more detail. For now, we want to keep it simple, so let’s just add a title property to our PRPRecipe. Open the header and add the property declaration like this: ViewsAndControllers/Recipes_01/Recipes/PRPRecipe.h ​​@interface PRPRecipe : NSObject​​ ​​​​ ​​@property(nonatomic, copy) NSString *title;​​ ​​​​ ​​@end​​ This property keeps track of our recipe’s titles. Of course, a real recipe would need more information: directions, a list of ingredients, and so on.

@property(nonatomic, strong) id dataSource;​​ ​​@end​​ Now let’s go update the implementation to use the data source rather than the array. We need to update the tableView:numberOfRowsInSection: method to use the dataSource, like this: TableViews/Recipes_07/Recipes/PRPRecipesListViewController.m ​​- (NSInteger)tableView:(UITableView *)tableView​​ ​​ numberOfRowsInSection:(NSInteger)section {​​ * ​​ return [self.dataSource recipeCount];​​ ​​}

block, so we just log a message. In an application that exposed multiple documents, this approach would not work. If the user were to tap on a document and it failed to open, we’d want to understand why that document was shown to the user in the first place rather than creating a new one. But for our application this approach works well. 7.2 Telling the Recipe Document About Edits We can add and delete recipes, and now whatever state the recipe list is in when we leave the app is the

we would have to set up a single, authoritative server first. In practical terms, Git encourages us to adopt source control early, which is one reason Xcode offers to set up a Git repository for new projects when we create them. Launch the Terminal application from /Applications/Utilities. We need to change our working directory to the Recipes directory via the cd command. If you’re not familiar with the command line, just type cd, a space character, and then drag the Recipes folder to the

provide banking information to receive payments. These steps can take days or even weeks to complete, so they should be worked out well before we need to launch the app. A SKU number, meaning an arbitrary string by which we will track sales of the app. A support URL and support email address. Don't Ship Programmer Art Deadlines are a fact of life. We have all been forced by one deadline or another to do something we didn’t want to do. But when that happens, skip features; don’t skip
