Custom UITableViewCell Class Issue

Question

I've read quite a few tutorials online about how to create a custom cell subclass, but I'm still a little confused. When I try to follow the instructions found in this question, I end up with errors that the tableView is not a valid property for the object of ViewController.

I've created a new subclass of UITableViewCell , called CustomBookClass . I've hooked up the properties with my CustomBookClass.h file.

#import <UIKit/UIKit.h>

@interface CustomBookCell : UITableViewCell

@property (weak, nonatomic) IBOutlet UIImageView *bookImage;
@property (weak, nonatomic) IBOutlet UILabel *bookTitle;
@property (weak, nonatomic) IBOutlet UILabel *dateAdded;

@end

I then go into my ViewController.m file to edit the viewDidLoad method.

- (void)viewDidLoad
{
[super viewDidLoad];

[self.tableView.delegate = self];
[self.tableView.dataSource=self];

[self.tableView registerClass:[CustomBookCell class]forCellReuseIdentifier:@"Custom    
Cell"];

}

I get an error on the tableView, saying the property doesn't exist, even though in the ViewController.h file, I'm including the table view.

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UITableViewDelegate,   
UITableViewDataSource>

@end

I'm sure I'm missing something really obvious here, as this is my first time trying this. Can anyone help me out? Thanks!

Answer 1

UIViewController does not have that property. Even if you assign the Delegate and DataSource protocols to it. There are a couple of things you can do however.

1. Link the table view to the ViewController yourself. That means, create a property/outlet called tableView .
2. Inherit from UITableViewController instead of UIViewController .

Both should work.

Edit: Oh and the lines:

[self.tableView.delegate = self];
[self.tableView.dataSource=self];

don't make sense. They should be either:

1. self.tableView.delegate = self; and self.tableView.dataSource = self;
2. Or [self.tableView setDelegate:self]; and [self.tableView setDataSource:self]

with 1 being preferred. (Edit: option #2 was actually incorrect code, my bad.)

Answer 2

No need to set delegate and datasource in TableViewCell class

simple make a property and synthesize your table view item

@property (weak, nonatomic) IBOutlet UIImageView *bookImage;

@property (weak, nonatomic) IBOutlet UILabel *bookTitle;

@property (weak, nonatomic) IBOutlet UILabel *dateAdded;

now import your cell class in your tableView controller class

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"SimpleTableCell";

    SimpleTableCell *cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
    if (cell == nil) 
    {

        //If you are using xib for representing your UI then add a nib file.

        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SimpleTableCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
    } 

    cell.bookTitle.text = [tableData objectAtIndex:indexPath.row];
    cell.bookImage.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
    cell.dateAdded.text = [prepTime objectAtIndex:indexPath.row];

    return cell;
}
