Xcode table view from array splitted - iphone

Question

I'm trying to get a tableview starting from a string in this format "name1,link1,name2,link2..."
So what i'm actually doing is this:
-Get the string and put links and names into an array, then split the array into two lesser ones by the position of the objects
- (void)viewDidLoad
{
NSString *dataString = #"a,www.google.it,b,www.apple.it,c,www.youtube.it";
dataArray = [dataString componentsSeparatedByString:#","];
for (int i=0; i<[dataArray count]; i++) {
if (i%2==0) {
[dataArrayName addObject:[dataArray objectAtIndex:i]];
}
else {
[dataArrayLink addObject:[dataArray objectAtIndex:i]];
}
}
[super viewDidLoad];
}
-Set up the table view
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
{
return [dataArrayName count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = #"myCell";
// Try to retrieve from the table view a now-unused cell with the given identifier.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
// If no cell is available, create a new one using the given identifier.
if (cell == nil) {
// Use the default cell style.
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"myCell"];
}
// Set up the cell.
NSString *cellName = [dataArrayName objectAtIndex:indexPath.row];
cell.textLabel.text = cellName;
return cell;
}
But when i run the application the view with the tableview is clear (there are empty rows)
What's the problem?

Answer 1

Have you initialized dataArrayName and dataArrayLink (ie, at some point, before you started adding objects to it, did you say dataArrayName = [[NSMutableArray alloc] init] or an equivalent?
