Tableview with custom cell not working

KingofChaos · July 2012

Hey everyone, I have this code so far for my tableview with custom cells,

#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 [self.array count];   
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{
   
    
   
    NSString *uniqueIdentifier = @\"customerCell\";
  
    
   
    CustomerCell  *cell = nil;
    
    cell = (CustomerCell *) [self.tableView1 dequeueReusableCellWithIdentifier:uniqueIdentifier];
    
    CustomerCell *array = [self.array objectAtIndex:[indexPath row]];
    
    if(!cell)
    
    {
       
        
       
        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@\"CustomerCell\" owner:nil options:nil];
        
        for(id currentObject in topLevelObjects)
            
        {
            
            if([currentObject isKindOfClass:[CustomerCell class]])
                
            {
            
                cell = (CustomerCell *)currentObject;
               
                break;
                
            }
          
        }
     
    }
    

    cell.label1.text = cell.name;

   
    return cell;
    
}



@end

but it keeps giving me the error "property 'name' not found on object of type 'CustomerCell'" and I dont know how to declare the property, Thank you for any help you can give.

Edit: Never mind. Read the code way too quickly, look at Duncan C's post.

Post the header for your custom cell type CustomerCell.

Also post the code that is throwing the error. I did not see any reference to "name" in the code you posted.

You might need to cast a generic cell to a CustomerCell before you can reference a property from your custom cell.

Part of the code you posted does not make sense to me. First you try to dequeue a reusable cell, which is fine. Then you try to extract another CustomerCell object that you call "array". If it's a custom table view cell, why do you call it array? And why are you storing table view cells to an array? The name "array" is a very confusing name for a table view cell. And, you should not be saving your table view cells into an array. That will prevent the system from deallocating them when it is done with them.

This is the code I am talking about.

    cell = (CustomerCell *) [self.tableView1 dequeueReusableCellWithIdentifier:uniqueIdentifier];
    
    //The following line does not make sense to me.
    CustomerCell *array = [self.array objectAtIndex:[indexPath row]];

Thank you for the replies, this is my CustomerCell.h file


#import <UIKit/UIKit.h>

@interface CustomerCell : UITableViewCell
{
    
}

@property (nonatomic, strong) IBOutlet UILabel *label1;
@property (nonatomic, strong) IBOutlet UIImageView *image1;

@end

And I just followed a tutorial and did what they told me to do, Im still a beginner, and am trying to learn how a tableview works with custom cells.

Sorry, forgot one of your questions, this is the line that is giving me the error:

cell.label1.text = cell.name;

Post the whole method that contains that line and put that line in bold.

I got that working, I just had to change the ".name" to "@"whatever""

Now I'm using this code:

- (CustomerCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    CustomerCell *cell = [tableView dequeueReusableCellWithIdentifier:@\"customerCell\"];
    if (cell == nil) {
        // Load the top-level objects from the custom cell XIB.
        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@\"CustomerCell\" owner:self options:nil];
        // Grab a pointer to the first object (presumably the custom cell, as that's all the XIB should contain).
        cell = [topLevelObjects objectAtIndex:0];
    }
    
    return cell;
}

And I get this error in the output:

2012-07-09 13:44:44.346 LYWAM Tour[394:10703] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<ViewController 0x761f280> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key image1.'
