Errata for iOS SDK Development

#48545: last paragraph before section 2.2 Methods and Messaging. Sentence: "In this case, it means PRPApplicationDelegate handles callback methods related to the life-cycle of the application and its interaction with the system."
Should this say "... means PRPAppDelegate handles callback ..."? --Russ Vollmer

#48546: Since this is a sort of an iOS Programming intro chapter, the reader may not know where to place an @property in a header file. At the top of page 31 in the sentence "Let’s begin by adding a property declaration to PRPViewController.h:" may want to include a mention of where to add the @property to the .h file (e.g. "... after the @interface ... " as is already done further down in the text on page 32 when adding the corresponding @synthesize. --Russ Vollmer

#48494: The connection to twitterWebView is automatically broken by deleting the webview. This might be due to a xcode update, but this was my experience. Looks like this part is no longer necessary:

"There’s also a connection that we need to break: control-click File’s Owner and in the HUD that appears, click the x button to break the connection to TwitterWebView."--SD

#48488: The name of the class to be created is never specified (though the superclass to use is...). It is shown in "figure 24" as PRPRecipe, but never in the text.--Mark Rakes

#48687: In "Intentionally Breaking Things", when telling how to restore the connection, "Control" would be preferable to "^" to specify the key to press. Although it is the symbol used when specifying key combinations, it is not the name of the key and it is not written in it.--Raúl Pedroche

#48610: Although it can be derived from the programming listing, you never specifically state the name for the "PRPRecipe" class when setting up the Objective-C class in the second paragraph for the "Model Class" section. I think it would be helpful to specific state: "For the name use 'PRPRecipe'."--Brian Kelly

#48656: Under 5.2 "Create a Table View Controller", paragraph two, the name of the UITableViewController subclass is not specified so you cannot progress through the "create new class wizard".

The name of the class, "PRPRecipesListViewController", can be found later - in paragraph 3 - but it seems it should be mentioned earlier.--Jonathan

#48535: The description of how to implement the PRPRecipesListViewController is a bit fuzzy. I think you mean to select Objective-C class and then then make sure it subclasses UIViewController. --David Loeffler

#48768: Figure 34 shows 7 items, but the sample code only created two. Perhaps change the description on page 86 to something like:

.. to create the array and add a few recipes:

And then the code to

recipe.image = [UIImage imageNamed:@"IMG_1948.jpg"];
[localRecipes addObject:recipe];
// feel free to add a few more recipes to fill up that table!
// ...
self.recipes = localRecipes;--Stephan Mantler

#48481: The code sample on this page includes "@end", which implies that this method should be placed just before the end of the implementation. Explicitly stating this within the page contents would help clear up where this should be positioned --donald hutchison

#48497: The text says, "Select the DocumentRecipes group;". This is correct for people who are using the example code, but it will appear to be a typo to readers who have been following along from the beginning, as their project and group will be called "StoryboardRecipes".--Scott Lumsden

#48503: On this page, the following instruction is given: "First, we don’t currently have a pointer to the existing doc. Fix that by adding a new property to the PRPAppDelegate, and changing the application:didFinishLaunch- ingWithOptions: method to assign the document created there to the new property." There isn't a listing for this, and if the reader checks the example code, he or she will probably be surprised to find that the property has been added to the implementation file instead of the header. It would be really helpful if this was specified in either the instructions or in a listing.--Scott Lumsden

#48512: It would be helpful to warn the reader that the app will no longer run in the simulator, and will only run on a device that has iCloud configured, once the code changes listed on this page are made. I spent quite a while trying to figure this out...--Scott Lumsden
