Tableview segue not working?

Question

Yesterday I was working on a project and I came across this error. Kept me up all night! Still no answer that fixes MY ERROR! So what happens is when i tap my cell its not going to next view controller. I made prototype and everything. So before it was giving be a signal sgbart or something and I fixed it with adding this.

This was in -(void)viewDidLoad

[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:CellIdentifier];

The error was coming up here -

 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

Now all that is fixed. Now whenever i go and click a cell its not working. It is a RSS reader project. Here is the full code.

Thank you guys for helping. By the way I have done all the re search I could do and all leaves me in failure and even more error so please try help me guys. Also I am new to Objective-C.

Answer 1

Do you implement didSelectRowatIndex method ? And set delegate ?

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;

Cheers S.
