Reload data - table empty - ios

Question

I have 2 tables view . One is with category and the other with videos .I added the favorite song into an array . But how can i reload my table with only the favorite videos when favorite category is selected ?
This is what i was trying but my table view is empty.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if (tableView.tag==0) {
TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
if (!cell) {
cell=[[TableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"cell"];
}
int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];
cell.title.text=[[stories objectAtIndex: indexPath.row] objectForKey: #"title"];
NSString * aux=[[stories objectAtIndex: indexPath.row] objectForKey: #"url"];
NSString * videoHTML =[NSString stringWithFormat: #"<iframe type=\"text/html\" width=\"100\" height=\"80\" src=\"%#\" frameborder=\"0\"></iframe>",aux] ;
NSString *imagine=[[stories objectAtIndex:indexPath.row]objectForKey:#"thumbnail"];
cell.imageSong.image=[UIImage imageNamed:imagine];
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:imagine]];
cell.imageSong.image = [UIImage imageWithData:imageData];
cell.imageSong.contentMode=UIViewContentModeScaleAspectFit;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (!tableView.tag==0) {
int row =indexPath.row;
if (row==0) {
self.title1.text=#"ALL SONGS";
[stories removeAllObjects];
[self parse];
i=0;
[self showMenu:nil];
}
else if (row==1) {
self.title1.text=#"FAVORITE";
b=[favoriteArray count];
if (b==0) {
NSLog(#"NSArray empty");
[[[UIAlertView alloc]initWithTitle:#"Attention !" message:#"No videos !" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil]show];
}
else{
[stories removeAllObjects];
[self.tableView reloadData];
i=0;
[self showMenu:nil];
}
}
else
{
self.title1.text=[categoryArray objectAtIndex:indexPath.row-1];
[stories removeAllObjects];
NSString * path =[feeds objectAtIndex:indexPath.row-1];
[self parseXMLFileAtURL:path];
i=0;
[self showMenu:nil];}
self.karaokeBTn.hidden=YES;
self.menu.hidden=NO;
self.title1.hidden=NO;
}
-(void)parse{
if ([stories count] == 0) {
for (int i=0; i<[feeds count]; i++) {
NSString * path =[feeds objectAtIndex:i];
[self parseXMLFileAtURL:path];
}
}
}
In favorite array i already have the url for video, title and image . i dont need to parse the feed again.

Maybe you want to reload your table after parsing:
-(void)parse{
if ([stories count] == 0) {
for (int i=0; i<[feeds count]; i++) {
NSString * path =[feeds objectAtIndex:i];
[self parseXMLFileAtURL:path];
}
[self.tableView reloadData];
}

I'm not exactly sure if I understood your issue. But since you said your tableView is empty heres a possible solution.
How do you set stories array? If it's a asynchronous data fetch from web, you have a empty stories array when those delegate methods get called.
You have to reload table view once data fetching is done. On the completion block of your data fetching method.
[self.tableView reloadData];
