Question

I have a custom object, Spaces:

#import "Spaces.h"


@implementation Spaces

@synthesize spaceName;
@synthesize spaceUsers;
@synthesize spaceIcon;
@synthesize spaceID;

@synthesize imageURLString;


- (void)dealloc
{
    [spaceName release];
    [spaceUsers release];
    [spaceIcon release];

    [imageURLString release];

    [super dealloc];
}

@end

My root view controller implements a cellForRowAtIndexPath: and grabs from an NSArray of Spaces:

    [[cell spaceName] setText:aSpace.spaceName];
    [[cell spaceChatType] setText:@"People"];
    [[cell spaceActiveUsers] setText:aSpace.spaceUsers];

This works fine and I can click to go into the detail view and back to the list, but after maybe 5-6 clicks back and forth between the table view and detail view, I get an error at [[cell spaceName] setText:aSpace.spaceName]; which is

‘-[__NSCFSet spaceName]: unrecognized selector sent to instance 0x6047b90′”

Please help! Any insight will be very appreciated!

UPDATE:

I’m still getting the same error but I’ve narrowed it down to the this:

-I’m creating a detail view controller on didSelectRowAtIndexPath…
-The detail view is being pushed to the viewcontroller and displays fine, I have a back button added as well.
-The detail view loads information and refreshes on a timer
-Pressing the back button goes back to the table list view

This is the problem my detail view is not being released from memory so the more I go back and forth between the views the more timers were going off simultaneously. I added a check to viewWillDisappear that stops the timer by setting a bool value.

I noticed that the detail view is not unloading…

From the RootViewController:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //no longer on initial view
    isinit = NO;

    //hide keyboard
    [spacesSearch resignFirstResponder];

    if (spaces != nil && spaces.count > 0)
    {
        //set back button reference
        UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Spaces" style:UIBarButtonItemStylePlain target:self action:@selector(returnSpacesList:)];  
        self.navigationItem.backBarButtonItem = backButton;

        [backButton release];

        DetailViewController *details = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil]; 

        //Grab Data from selected Space object and pass to DetailViewController
        Spaces *aSpace = nil;
        if (tableView == self.searchDisplayController.searchResultsTableView)
        {
            if ([self.filteredListContent count] == 0)
            {
                //self.lastSearchText
                NSLog(@"Create new space code!");
            }
            else
            {
                aSpace = [self.filteredListContent objectAtIndex:indexPath.row];
            }
        }
        else
        {
            aSpace = [spaces objectAtIndex:[indexPath row]];
        }

        //set title and display
        self.navigationController.title = [NSString stringWithFormat:@"/%@/",aSpace.spaceName];

        //pass data
        [details passedValue:aSpace.spaceID :aSpace.spaceName];

        [self.navigationController pushViewController:details animated:YES];

        [aSpace release];
        [details release];

    }
}

How can I force the detail view to be released from memory?

Thank you

It sounds like [cell spaceName] has been autoReleased. I cannot see how you have defined that, but take a look at that part of your code.
If you need more help, you need to provide more code.
