iOS Why Is My Image Not Showing Up (From Web Service)

[loon3y]

(Tabbar App)

im calling a web service in my first viewcontroller and I'm trying to set it to an array and make it appear on my salesviewcontroller's table

if ([elementName isEqualToString:@"itemno"])
    {
        
        displayText.text = capturedCharacters;
        if([capturedCharacters isEqualToString:@""])
        {
            
        }
        else
        {
          theDataObject.prodCode = capturedCharacters;
            
            NSString *sURL = [[NSString alloc] initWithString:[NSString stringWithFormat:@"%@%@.jpg", theDataObject.imageURL, salesIMG.salesCode]];
            
            NSData *mydata = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",sURL ]]];
            
            salesIMG.styleImage = [[UIImage alloc] initWithData:mydata];
        }
    }

salesIMG.styleImage is the global variable where im storing my data, and heres the coding for my tableview in the salesVIewController

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    GlobalStrings* theDataObject = [self theGlobalClass];
    static NSString *CellIdentifier = @"SalesCell";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    
    Sale *mySale = [Sale alloc];
    mySale = [theDataObject.prodTableArray objectAtIndex:[indexPath row]];
    
    UILabel *codeLabel = (UILabel *) [cell viewWithTag:100];
    codeLabel.text = mySale.salesCode;
    UILabel *descriptLabel = (UILabel *) [cell viewWithTag:101];
    descriptLabel.text = mySale.salesDescript;
    UILabel *priceLabel = (UILabel *) [cell viewWithTag:103];
    priceLabel.text = mySale.salesPrice;
    UIImageView *salesImageView = (UIImageView *) [cell viewWithTag:102];
    UILabel *quantityLabel = (UILabel *) [cell viewWithTag:104];
    quantityLabel.text = mySale.salesQuantity;
    
    
    salesImageView.contentMode = UIViewContentModeScaleAspectFit;
    
    salesImageView.image = mySale.styleImage;
    
    return cell;
    
}

it worked for the other app, im not sure why it doesnt work. i need to do this because there is a 5-8 second delay when i press the the salesviewcontroller tab, because before i was calling the webservice everytime to show the image
