EDITED to show the relevant part of the code
Hi. There's a strange problem with an NSMutableArray which I'm just not understanding...
Explaining:
I have a NSMutableArray, defined as a property (nonatomic, retain), synthesized, and initialized with 29 elements.
realSectionNames = [[NSMutableArray alloc] initWithCapacity:29];
After the initialization, I can insert elements as I wish and everything seems to be working fine.
While I'm running the application, however, if I insert a new element in the array, I can print the array in the function where I inserted the element, and everything seems ok.
However, when I select a row in the table, and I need to read that array, my application crashes. In fact, it cannot even print the array anymore.
Is there any "magical and logical trick" everybody should know when using a NSMutableArray that a beginner like myself can be missing?
Thanks a lot.
I declare my array as
realSectionNames = [[NSMutableArray alloc] initWithCapacity:29];
I insert objects in my array with
[realSectionNames addObject:[category categoryFirstLetter]];
although I know i can also insert it with
[realSectionNames insertObject:[category categoryFirstLetter] atIndex:i];
where the "i" is the first non-occupied position.
After the insertion, I reload the data of my tableView. Printing the array before or after reloading the data shows it has the desired information.
After that, selecting a row at the table makes the application crash. This realSectionNames is used in several UITableViewDelegate functions, but for the case it doesn't matter. What truly matters is that printing the array in the beginning of the didSelectRowAtIndexPath function crashes everything (and of course, doesn't print anything). I'm pretty sure it's in that line, for printing anything he line before works (example):
NSLog(@"Anything");
NSLog(@"%@", realSectionNames);
gives the output:

Still not understanding what kind of stupidity I've done this time... maybe it's not too late to follow the career of brain surgeon?
