UITableView delegate and datasource in a separate class after parsing

I need to set my UITableView delegate and datasource from a separate class (data ready after parsing called by a method), but every time my table is emtpy. I’m using ARC and this is simplified code: //HomeViewController.h #import <UIKit/UIKit.h> #import “TableController.h” @interface HomeViewController : UIViewController { IBOutlet UITableView *table; TableController *tableController; } @end and //HomeViewController.m […]

Apple id account belonging to two teams getting “Your account already has a valid iOS Distribution certificate”

Difference between unwind segue and delegation
