Problem in loading a NSMutablearray value into table view? - uitableview

Question

I am new to iphone development, I am trying to load a NSMutableArray values into a table view, I am using code below for this which generates error as specified. Can some one help me in rectifying this error.
code :-
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return [ShowList count];
}
// Customize the appearance of table view cells.
- (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];
}
// Configure the cell...
NSString *cellValue = [ShowList objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
return cell;
}
error :-

#Ravi your array is array of array that is the ShowList is an array which has first object as array and that array is that

so you can do something like this.
NSString *cellValue = [[ShowList objectAtIndex:0] objectAtIndex:indexPath.row];

Answer 2

I assume UILabel's setText calls isEqualToString for some reason, so it crashes for the very first object in your array which is not a NSString.
