Table View Crashing When Accessing Array of Dicitonarys - iphone

Question

All,
When my table view loads, it accesses several delegate methods. When I configure the cell, I have it calling this method (where "linkedList" is an array of dictionarys):
- (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];
}
// Configure the cell...
VUWIManager *vuwiManager = [VUWIManager sharedVuwiManager];
NSLog(#"%#", [[vuwiManager linkedList]objectAtIndex:indexPath.row]);
NSLog(#"TESTZOMGOFDSOJFDSJFPODJSAPFDS");
cell.textLabel.text = [[vuwiManager linkedList]objectAtIndex:indexPath.row];
return cell;
}
It crashes at the line cell.textLabel.text = [[vuwiManager linkedList]objectAtIndex:indexPath.row]; - I know I'm doing something wrong here but I'm not sure what it is. Again, linkedList is a NSMutableArray of NSDictionarys.
Edit: if I call cell.textLabel.text = [[vuwiManager linkedList]objectAtIndex:indexPath.row]; it returns:
{
IP = "192.168.17.1";
desc = "description";
}
in the debugger. Just thought I'd give a little bit of formatting details.
Thanks

Answer 1

You are trying to assign an object NSDictionary to cell.textLabel.text, which must be passed a NSString.
Did you want :
NSString *s = [NSString stringWithFormat:#"%#",
[[vuwiManager linkedList]objectAtIndex:indexPath.row]];
cell.textLabel.text = s;
?

Answer 2

Setting an NSString * to an NSDictionary * will likely result in a crash when it tries to access any string methods that are not implemented in the dictionary. If you want that string you are logging add a call to description.
cell.textLabel.text = [[[vuwiManager linkedList]objectAtIndex:indexPath.row] description];

Answer 3

It looks like you are setting cell.textLabel.text to a NSDictionary instead of an NSString. If linkedList is an NSMutableArray of NSDictionaries, then you need to add on objectForKey:#"String key" to access the string
cell.textLabel.text = [[[vuwiManager linkedList]objectAtIndex:indexPath.row] objectForKey:#"STRING_KEY_HERE"];
