Hello: I'm working with the flag images in Chapter3 using xcode 4.2. I was debugging when I tried changing the names of the .png files to be 1.png and 2.png instead of USA.png and Taiwan.png - thinking that was the issue. However, The issue was elsewhere and I fixed it.

However, once I fixed the issue to show the images - ALL four of the flag images show up fine. So I think I have a gap in my understanding of where the images are referenced in my MasterViewController.m. I believe that the following statment points to the .png image files...

(p65) filePath = [[NSBundle mainBundle] pathForResource:product.countryOfOrigin ofType:@"png"];

I deleted the file from the supporting files folder in xcode using delete references only. Then I deleted the files using finder. I deleted the *.png files everywhere I could find them on the mac... but the images still appear when I run the build. I did a clean (Command-Option-Shift-K), but still have issue. I also read about deleting the build folder but not sure where/what that is or how/whether to do that.

I obvoiusly have a hole in my understanding of this technology until I can solve this mystery. Any help is appreciated. Thanks.

I assume you are running the program in the simulator. Try deleting the program from the simulator. (it is the same as removing a program from the iPad, click and hold on the the icon until the "jiggling" starts and then click the "x" in the upper left corner of the icon).
Occasionally you may want access to the actual installed program in the simulator. They are located in ~/Library/Application Support/iPhone Simulator which has subfolders for the supported iOS versions (the most recent being 4.3.2 and 5.0). In these subfolders is an application folder that has each application bundle named with a long id string. Inside this folder is the executable, Document and other support files for the application. In Mac OS X 10.7 the user library folder is hidden (not visible in the Finder), but it can be accessed through the Finder>Go>Users/"Your Username"/Library or via the terminal. If deleting the application bundle does not solve your problem, feel free to send the project to

and I will sort it out for you.

Yes - I'm using the simulator. using your tip I eventually got it to work. But it got stanger for me. I mistakenly deleted the supporting files folder in xcode so I reverted to backup after Chapter 2 - before any images were included at all! Then I read your post (thank you) and I removed the program from simulated iPad. I then ran the Chapter 2 backup and the images were still there. I removed program from simulated iPad again and ALSO "clean"ed project in xcode 4.2 and now I see that boring old list from Chapter 2 - as expected. I suppose once I get the developer license and test with the handheld then this type of issue will disappear. Thanks for the help!
