    <p>I'm glad to see that my code is proving useful! :)</p> <p><code>CHCSVParser</code> is similar in behavior to an <code>NSXMLParser</code>, in that every time it finds something interesting, it's going to let you know via one of the delegate callbacks. However, if you choose to ignore the data that it gives you in the callback, then it's gone. These parsers (<code>CHCSVParser</code> and <code>NSXMLParser</code>) are pretty stupid. They just know the format of the stuff they're trying to parse, but don't really do much beyond that.</p> <p>So the answer, in a nutshell, is "you have to save it yourself". If you look at the code for the <code>NSArray</code> category, you'll see in the .m file that it's using <a href="http://github.com/davedelong/CHCSVParser/blob/master/NSArray%2BCHCSVAdditions.m#L30" rel="noreferrer">a simple <code>NSObject</code> subclass as the parser delegate</a>, and that subclass is what's aggregating the fields into an array, and then adding that array to the overall array. You'll need to do something similar.</p> <p>Example delegate:</p> <pre><code>@interface CSVParserDelegate : NSObject &lt;CHCSVParserDelegate&gt; { NSMutableArray * currentRow; } @end @implementation CSVParserDelegate - (void) parser:(CHCSVParser *)parser didStartLine:(NSUInteger)lineNumber { currentRow = [[NSMutableArray alloc] init]; } - (void) parser:(CHCSVParser *)parser didReadField:(NSString *)field { [currentRow addObject:field]; } - (void) parser:(CHCSVParser *)parser didEndLine:(NSUInteger)lineNumber { NSLog(@"finished line! %@", currentRow); [self doSomethingWithLine:currentRow]; [currentRow release], currentRow = nil; } @end </code></pre> <p>However, I could be convinced to modify the behavior of the parser to aggregate the row itself, but if I go down that route, why not just have the parser aggregate the entire file? (Answer: it shouldn't)</p>

    1. COThanks for the answer - I couldn't tell if the parser did this work for you (through `currentChunk` or some other way)! It would be nice not to have to manually do the aggregation, but for most apps CSV parsing is only really used in a few places for I/O.If someone wanted to write that little bit of code once, would it be possible to subclass or write a category on the CHCSVParserDelegate?

    2. CO@Neal `CHCSVParserDelegate` is a protocol, so you can't subclass it. In order to get this behavior to work, you'd have to alter `CHCSVParser` directly or subclass it. The simplest answer is to aggregate the line yourself (like I do in the answer)

    3. CODidn't think so... Well thanks again very much for the wonderful work here! Actually a minor correction to your code... in `didEndLine` we need to change `currentLine` to `currentRow`. (i'd change it but don't have enough XP ;))

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
