Populating dbmanager Data into UITableView

im new to iOS development. This is small Restaurant type app. depending on restaurant it will populate the promotions. i have done all that so far and getting list of promotion to array in viewdidLoad method.

if (!dbmanager)dbmanager = [[DBManager alloc]init];
    array = [dbmanager getPromotions:[NSNumber numberWithInt:restId]];
    NSLog(@"%lu", (unsigned long)array.count);

and using this i can get the details of Promotion Details into Log

for (PromotionTbl *order in array) {
        NSLog(@"%@",order.promoName);
    }

i want to populate these data in tableview so i have done the normal implemantation for tableview and

add cell like this

cell.textLabel.text = [[array objectAtIndex:indexPath.row]objectForKey:@"promoName"];

but im getting error saying

2015-11-16 11:20:35.825 Eatin[2858:1201859] -[PromotionTbl objectForKey:]: unrecognized selector sent to instance 0x7ffb507b3ab0 2015-11-16 11:20:35.834 Eatin[2858:1201859] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[PromotionTbl objectForKey:]: unrecognized selector sent to instance 0x7ffb507b3ab0'

I have done without objectForKey as well.

You need to get object of PromotionTbl and then you can access the properties of the model.

PromotionTbl promotionModel = (PromotionTbl*)array[indexPath.row];

if(promotionModel != nil) {
    cell.textLabel.text = order.promoName;
}

For displaying data into cell, do like this : 

PromotionTbl *order = [array objectAtIndex:indexPath.row];
cell.textLabel.text = order.promoName;
cell.imageView.image = order.promotionImage; // If you want to display as a logo or thumbnail

// If you have image URL and download image from it and then display
[NSURLConnection sendAsynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:order.promotionImageURL]] queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {

    if (data)
    {
        cell.imageView.image = [[UIImage alloc] initWithData:data];
    }
}];

If you want to display large image then, add UIImageView and UILabel to cell and assign data to it. Or you can create custom cell having UIImageView and UILabel.

if you really sure that your array contain PromotionTbl, you can cast the object in array to PromotionTbl and access its value.

PromotionTbl *order = (PromotionTbl*)[array objectAtIndex:indexPath.row];
cell.textLabel.text = order.promoName;
