Question

I’m trying to show data from a plist file in a custom UITableViewCell.

Here is my rootViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSString *path = [[NSBundle mainBundle] pathForResource:@"projects" ofType:@"plist"];
    projects = [NSArray arrayWithContentsOfFile:path];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
        int n = indexPath.row;
        for (n=1; n<4; n = n+1) {

            NSDictionary *temp = [projects objectAtIndex:indexPath.row];
            projectCell.name.text = [temp valueForKey:@"name"];
        }
    }
    return projectCell;
}

The plist file i created only contains 4 dictionaries. And each one of them contains 2 strings. But I only want one of them to be in the cell. (I already created the UITableViewCell file named “ProjectCell”.

I’m just starting, so my question might be really basic. But I spent so much time trying to figure it out.

Could anyone help me out?

EDIT: when i build and run, it always gives me a blank table

EDIT2: Interface of ProjectCell

@interface ProjectCell : UITableViewCell {

IBOutlet UILabel *name;
IBOutlet UITableViewCell *theCell;

}

@property (nonatomic,retain) IBOutlet UILabel *name;
@property (nonatomic,retain) IBOutlet UITableViewCell *theCell;

@end

EDIT3 ProjectCell.m

@implementation ProjectCell

@synthesize name,theCell;

@end

You would be better off adjusting the XIB a bit.

• Click on the UITableViewCell object and change its class to ‘ProjectCell’ using the identity inspector.
• Now wire the IBOutlet name from this object to the existing label.
• Select the File's Owner and set it back to NSObject.

Now your ProjectCell.h,

@interface ProjectCell : UITableViewCell {
    IBOutlet UILabel *name;
}
@property (nonatomic,retain) IBOutlet UILabel *name;
@end

and your ProjectCell.m,

@implementation ProjectCell
@synthesize name;
@end

And the final changes will be in tableView:cellForRowAtIndexPath: method,

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

    ProjectCell *cell = (ProjectCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
            NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@”ProjectCell” 
                                                                     owner:nil 
                                                                   options:nil];

            for(id currentObject in topLevelObjects)
            {
                if([currentObject isKindOfClass:[ProjectCell class]])
                {
                    cell = (ProjectCell *)currentObject;
                    break;
                }
            }
        }

    NSDictionary *temp = [projects objectAtIndex:indexPath.row];
    cell.name.text = [temp valueForKey:@"name"];

    return cell;
}
