Okay so i have been fiddling with some iOS development, I am fairly new to this. Usually more of a PHP and JavaScript guy. But here is my issue... in my app I am creating that pulls a friendslist from a local xml file (it will be pointing to a php page on a server that generates a users friendslist but for simplicity sake of debugging and development I am using local.)
I have a View Controller (storybaord) that is loaded when I click "friends", as of now, the view loads but with no data, in the debugger I can see that its pulling the data from the XML, so I thought, okay maybe the TableView is never being called, so i put a breakpoint on the
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
But the app still continued to load the page,
So to recap I have a View Controller, with a search bar, toolbar and a table view, the table view has a placeholder cell given the identifier Cell, heres the coding the for friendsListTableViewController.h

//EDIT//
I got a little further, thanks to some advice listed in the comments below before it wouldnt break at numberOfSectionsInTableView or numberOfRowsInSection but now it will break when i put a break on the numberOfSectionsInTableView or numberOfRowsInSection but still not the cellForRowAtIndexPath
