View Full Version : Why Is My Image Not Showing Up (From Web Service)

(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:@""])

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
