Mar 19, 2009 issue 27 (Navigation Controller functionality along with TabBarControl...) reported by sumitmorey - Firstly I'm a newbie. I've developed an iphone app and written code in appDelegates' applicationDidFinishLaunching and have being able to achieve: 1. Successfully add TabBarController and NavigationController together. 2. I've added my ViewControllers to TabBarController 3. Initialized NavigationController using TabBarController What is the expected output? What do you see instead? I want to add Navigation button on NavigationController so that my app would work like a normal Navigation controlled app. All the view will have TabBarContoller at the bottom of screen. What version of the product are you using? On what operating system? XCode 3.1.2, Simulator 2.1, MAC OSX 10.6.2 Please provide any additional information below. Looking forward for positive response.

Mar 16, 2009 issue 26 (Problems with Chapter 3 Walktrough ) commented on by justinmound - Isssues resolved, but I am now convinced that these problems are related to the book being written for an previous version of the SDK. I am no expert, but here are the things you need to know if you too want to do the walkthrough with the (currently) latest version of Xcode (3.1.2): 1. As stated above, when you create a new project as a view-based application, you will get 2 .xib files. Figure 3-1, p.83 shows only one. Don't be confused, the text is correct, the one to edit is indeed MainWindow.xib. 2. Fig. 3-2 is missing the "First Responder" object in the project window. Ignore it. 3. Fig. 3-2 is also missing a View Controller. Interface Builder creates one for you so you don't have to create one yourself as the book states in Step 8 (p. 86). You do have to create a View, though. 4. If you follow the instructions exactly, you'll have two errors that will show as a warning/explanation point in Interface Builder's project window. The first is that you will need to remove the NIB name from the MyViewController. You'll see it in the inspector under the attributes tab. The second is that there is an extraneous outlet in WalkThroughAppDelegate. It needs to be removed. See the attachment "WalkThroughAppDelegate.png" Anyone, please correct me if I am wrong. If I'm correct, Erica, can you update the errata page as well, so others may not suffer as I have. :) Isssues resolved, but I am now convinced that these problems are related to the book being written for an previous version of the SDK.

I have tried the walkthrough three times, looked at the errata, and looked at the issues page, to no avail. If I create a "View-based Application" and open its MainWindow.xib, there are no errors, and it will build fine. However, if I remove the classes and replace main.m with your code, I see the attached error in Interface Builder. I am fairly certain that the error in IB is connected to the iPhone Simulator crashing, but I haven't figured out what the problem is yet. Some observations: - When I create a new project as a "View-Based Application," I get 2 .xib files, one MainWindow.xib and one based on the name of the new project, in my case, "WalkThroughViewController.xib". In Fig. 3-1, you only have one listed, MainWindow.xib - You commented on Issue 1 that there is indeed an error, but the correction is not listed in the errata, which leaves it confusing.

Nov 22, 2008 issue 15 (Extended XMLParser and TreeNode to add attributes and useful...) reported by adrian.cockcroft - What steps will reproduce the problem? 1. Parse a complex XML feed 2. Notice that the XML attributes are not being collected 3. Try to find complex deeply nested leaf nodes with specific attributes 4. Use this code instead :-) I needed to parse the Netflix API, which has a complex REST/XML schema, so I extended the example code. Many thanks for the cookbook example, it was very very useful.

issue 26 (Problems with Chapter 3 Walktrough ) commented on by justinmound - Isssues resolved, but I am now convinced that these problems are related to the book being written for an previous version of the SDK. I am no expert, but here are the things you need to know if you too want to do the walkthrough with the (currently) latest version of Xcode (3.1.2): 1. As stated above, when you create a new project as a view-based application, you will get 2 .xib files. Figure 3-1, p.83 shows only one. Don't be confused, the text is correct, the one to edit is indeed MainWindow.xib. 2. Fig. 3-2 is missing the "First Responder" object in the project window. Ignore it. 3. Fig. 3-2 is also missing a View Controller. Interface Builder creates one for you so you don't have to create one yourself as the book states in Step 8 (p. 86). You do have to create a View, though. 4. If you follow the instructions exactly, you'll have two errors that will show as a warning/explanation point in Interface Builder's project window. The first is that you will need to remove the NIB name from the MyViewController. You'll see it in the inspector under the attributes tab. The second is that there is an extraneous outlet in WalkThroughAppDelegate. It needs to be removed. See the attachment "WalkThroughAppDelegate.png" Anyone, please correct me if I am wrong. If I'm correct, Erica, can you update the errata page as well, so others may not suffer as I have. :)
