Question

I am developing a application in that I want to print the array value in the cell contain label place. I got the vlaues for array like names=[results valueForKey:@"name"].

I write the code for print that value in a lable in cellForRowAtIndexPath like

-(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];
    }
    NSInteger row=indexPath.row;

    cell = [self getCellContentView:CellIdentifier];
    UILabel *lblTemp1 = (UILabel *)[cell viewWithTag:1];
        lblTemp1.text = [names objectAtIndex:row];
    //lblTemp2.text = [names objectAtIndex:row];
    return cell;
}

but ,when the application got the error at lblTemp1.text = [names objectAtIndex:row] like Program received signal: “EXC_BAD_ACCESS”.So please tell me how to solve this problem.

Answer 1

It seems you’ve missed to retain the array names. Try,

names = [[results valueForKey:@"name"] retain];

You could consider using declared properties to overcome the overhead of retaining and releasing the objects.
