iOS 3rd Edition Errata

In Chapter 28, when adding JSON support to the RSSChannel, you are asked to implement readFromJSONDictionary: in RSSChannel.m

The format of the JSON data is now a bit different, so you'll need to swap out a line in this method:

Code: Select all

- (void)readFromJSONDictionary:(NSDictionary *)d
{
    NSDictionary *feed = [d objectForKey:@"feed"];
   
    // DELETE THIS LINE
    // [self setTitle:[feed objectForKey:@"title"]];

    // ADD THIS LINE
    [self setTitle:[[feed objectForKey:@"title"] objectForKey:@"label"]];
   
    NSArray *entries = [feed objectForKey:@"entry"];
    for(NSDictionary *entry in entries) {
        RSSItem *i = [[RSSItem alloc] init];
       
        [i readFromJSONDictionary:entry];
       
        [items addObject:i];
    }
}


In Chapter 17, you are asked to use ibtool to generate localizeds XIB file. The book suggests you do like so:

Code: Select all

ibtool --import-strings-file ~/Desktop/DetailViewController.strings --write
    /iphone/Homepwner/Homepwner/es.lproj/Homepwner.xib
    /iphone/Homepwner/Homepwner/en.lproj/Homepwner.xib


However, this creates XIB files named Homepwner.xib, when really, it should be creating XIB files named DetailViewController.xib. Update it so the two output paths end with DetailViewController.xib.

Code: Select all


ibtool --import-strings-file ~/Desktop/DetailViewController.strings --write
    /iphone/Homepwner/Homepwner/es.lproj/DetailViewController.xib
    /iphone/Homepwner/Homepwner/en.lproj/DetailViewController.xib

Chapter 4, page 95, second paragraph. The sentence that reads "Select the debug navigator." should read "Select the breakpoint navigator."

Chapter 11 - page 229:

You'll need to implement tableView:didSelectRowAtIndexPath: ( page 230 ) if you want to see the exception when you tap a row.

for those of us who have gone digital can we have location point data as well as page numbers for the errata - page numbers now mean nothing on Kindle and I'm having trouble finding the spots to make with a note. cheers

For the first project, initWithNibName is recommended. However, it is not being called and the arrays are not being initialized. (Xcode 4.3.2)
Changing action from initWithNibName to viewDidLoad fixes the issue. An explanation from the authors would be helpful on this.

Are you sure you are using initWithNibName:bundle:?

I am also facing the same problem, I did set the debug points array questions and answers are null, I did pt pointer on SELF just currentIndexCounter is increasing in that.

Chapter 10 - Section 'Editing Mode' - the paragraph after two code snippets tableView:viewForHeaderInSection and tableView:heightForHeaderInSection

The second sentence reads - ... The first time tableView:heightForHeaderInSection: is sent to ItemViewController ....
Is it referring to tableView:viewForHeaderInSection instead??

Sorry that as I'm using Kindle version on iPad, which doesn't show page number but location only, I can only locate the paragraphs/ sentences as above.

Agree with this. I bought the Kindle version, page numbers meaningless.

Thanks.

Figures 9.8 and 9.9 both refer to a method and static variable named "defaultStore" which should instead be references to the method and static variable named "sharedStore".
