I have a ViewController where I enter a key through a textBox. The entered key pulls out all available records from a database where the same key is found. The list of the records forms NSMutableArray that I pass to UITableViewController, where the user can pick one. Then on the initial ViewController, this value should be selected.
Two issues:
1. Is there a way to open the TableViewController as modal and programmatically (not with the StoryBoard)? I have some "if" statements there that should control whether the TableViewController opens.
2. I cannot pass the array from the ViewController to TableViewController. Since I have no answer for question 1, I am doing it using another button (test). NSLog in UITableViewController tells me that the array there is null.
UIViewController.h:
UIViewController.mm
UITableViewController.h
UITableViewController.mm
In the end, I have:
I have been fighting this dilemma for a week already, although it should be a simple thing to do. I would really appreciate people's help!
