Dear Bob,

I would like a copy of the project which you have sent to "tecky10". I've sent you an e-mail.

Thank you and thanks in advance.
Best regards, Michael

Thank you very much Bob,

that has helped me a lot.

Best regards, Michael

Bob,

I'd LOVE a copy of that too. Is that possible?

Thanks so very much.

Send an email to

with your request and I will reply with the project as an attachment.
I will be away from my computer for the next 5 hours, so will not be able to respond immediately.

Bob,

Wow, you're pretty popular! I know you're going to send me the code of your fix, but I'm trying to understand this. As I'm doing the exercise in ch. 3 i'm converting it to xcode 4... BLINDLY... anyway I'm getting an abort when I execute the statement in the main routine:

return UIApplicationMain(argc, argv, nil, NSStringFromClass([SampleTableProjectAppDelegate class]));

this is what's in the error console:
2012-03-03 20:58:21.449 Catalog[49999:207] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 1 beyond bounds [0 .. 0]'

I KNOW that it's reading the DB correctly because I put breakpoints in and saw the data in the array.

Any ideas of what might be the problem?

All help is appreciated. Thanks so much!

I am assuming that you are doing the first version of the Chapter 3 program, and that by "converting to Xcode 4" you mean to use automatic reference counting. Two options to handle the conversion:
1. Code the program as in the book without using ARC, so that it compiles and runs. Then turn on ARC and choose Edit>Refactor>Convert to Objective-C ARC… Save the changes and compare what is different. That in conjunction with the documentation and developer video should be helpful.
2. Send me your project and I will see where you went astray.

Bob

Hi Bob (isn't that a drinking game? lol)

Thanks for the tip. I will send you my code because I don't want to just solve my problems, I need to understand them, otherwise I'll just create them again.

And yes, by converting to xcode 4 I was speaking of the ARC thing.

I'll send my code from my email acct.

thanks again, Bob.

Hi Bob, (I fear I may have availed myself of your generosity too much, I pray that is not the case)

I've got one last LARGE hurdle in converting your sample catalog app to my app.

the problem is I get a sigabrt when I type in the first letter of a search, in the search box.

It's bombing on the line:
Now the BIG DIFFERENCE between your code and mine is that when I display the contents of self.filteredAnswercards prior to the offending line it shows the value as (null), but when I display self.filteredProducts (in your version) prior to that line it shows an empty array as follows:

"the value of self.filteredProducts =(
)"

An empty array, with the right paren landing on the next line -- and it spills to the next line no matter how short I make the preceeding text, so it's either white space and a new line or just a newline???

I define it just like you do in the RootViewController.h:

I searched both versions for the string filteredAnswercards or filteredProducts (depending on which version, obviously) and they are mentioned in the exact same places with the same syntax.

I AM STYMIED and DESPERATE!!! PLEASE grace me with your generosity one more time. And please, let me treat you to some Starbucks or something.

Thank you in advance.

Message to all: I have found the solution with the help of several people. The problem I was having WAS with the predicate string.. .in it I spelled the field name incorrectly that I was filtering on. (one letter off... no error because it's really only a string) So, my warning to the noob world... beware the predicate!!! I don't know if this will help anyone, but, I hope it does.
