1. I need a small proof of concept for a global variable to enable me to pass data from a UITableView UILabel (within a ViewController) to another ViewController UILabel (through a Navigation Controller relationship).
2. I need a small proof of concept to instantiate a global class (NSObject or a singleton) within a RootViewController (from an NSDictionary of NSArrays) to pass data to another ViewController.
**Please provide working solution and comments.
