Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.

UITableView keeps freezing

Hello, I followed this tutorial on how to make a UITableView, Creating a simple TableView based iPhone application in xCode 4.2 - YouTube
And whenever I click the button that goes to the next view controller, it freezes and gives me these errors:
Click Here For Image

Any help would be appreciated.

    Copy paste your console (it's the text where it says "terminate called throwing an exception).
    If you are looking for a quality developer, I'm your man. Give me a PM if you are interested.

    No it isn't. The delegate message is being sent to a plain UIViewController object. Somewhere the custom view controller should be specified instead.

    So I've been trying everything to try and fix this, I even set up a custom cell to see if that would work, using this code:

    //
    //  ViewController.m
    //  LYWAM Tour
    //
    //  Created by Alan Raff on 6/28/12.
    //  Copyright (c) 2012 __MyCompanyName__. All rights reserved.
    //

    #import \"ViewController.h\"

    @interface ViewController ()

    @end

    @implementation ViewController
    @synthesize tableView1;
    @synthesize array;


    - (void)viewDidLoad
    {
        [super viewDidLoad];
    	// Do any additional setup after loading the view, typically from a nib.
        
        grommetext1.keyboardType = UIKeyboardTypeNumberPad;
        
        
    }

    - (void)viewDidUnload
    {
        [super viewDidUnload];
        // Release any retained subviews of the main view.
    }

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
    {
        return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
    }

    #pragma mark

    - (NSInteger)tableView:(UITableView *)tableView
     numberOfRowsInSection:(NSInteger)section
    {
        return 10;   
    }

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        NSString *uniqueIdentifier = @\"customerCell\";
        
        CustomerCell *cell = [tableView1 dequeueReusableCellWithIdentifier:uniqueIdentifier];
        
        if(cell == nil)
        {
            NSArray *views = [[NSBundle mainBundle] loadNibNamed:@\"CustomerCell\" owner:nil options:nil];
            
            for (id obj in views) {
                if([obj isKindOfClass:[UITableViewCell class]])  
                {
                    cell = (CustomerCell*)obj;
                    break;
                }
            }
        }
        return cell;
    }




    @end



    Then I get this in the output:

    2012-07-04 23:39:51.961 LYWAM Tour[1931:f803] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSObject 0x686f140> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key image1.'
