Put Core Data values in an array - objective-c

Question

I need to put the values retrieved using a Fetch Request from my core data graph into an array, but not entirely sure how to go about this.
I'm using the following to perform the fetch:
NSString *entityName = #"Project"; // Put your entity name here
NSLog(#"Setting up a Fetched Results Controller for the Entity named %#", entityName);
// 2 - Request that Entity
NSFetchRequest *request = [NSFetchRequest fetchRequestWithEntityName:entityName];
// 3 - Filter it if you want
request.predicate = [NSPredicate predicateWithFormat:#"belongsToProject = %#", _selectedProject];
// 4 - Sort it if you want
request.sortDescriptors = [NSArray arrayWithObject:[NSSortDescriptor sortDescriptorWithKey:#"dateTaken"
ascending:YES
selector:#selector(localizedCaseInsensitiveCompare:)]];
// 5 - Fetch it
self.fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request
managedObjectContext:self.managedObjectContext
sectionNameKeyPath:nil
cacheName:nil];
[self performFetch];
As you can see, i'm filtering the values that come back using an NSPredicate.
How would I get these values into an array and also be able to select individual attributes for the entity once they are in the array, for example the project.description or project.name?
Thanks to Eimantas I've got the objects in an array, however I still need to do two things:
Loop through the array and output the data into some HTML
Individually select attributes from the array, for example, the project description.
I'm using the following for loop to do the first:
for (int i=0; i < [projectListArray count]; i++)
{
NSString *tmp = (NSString *)[projectListArray objectAtIndex:i];
}
However, this is returning the error:
-[Project length]: unrecognized selector sent to instance 0x1b9f20
2012-03-28 10:48:35.160 Project App[3973:707] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[Project length]: unrecognized selector sent to instance 0x1b9f20'
It appears as though i might not be incrementing?

Answer 1

[self.fetchedResultsController fetchedObjects] returns the array of fetched objects.
update
It's better to use fast enumaration, not a for loop:
for (Project *project in projectListArray) {
NSString *projectDescription = [project valueForKey:#"description"];
}
You're getting the exception because you're casting an object to NSString while it's a pointer to (I presume) Project managed object.
