Chaining VCs from ViewModels
View ViewModelServices.m
- (void)pushViewModel:(BaseViewModel *)nextViewModel
{
NSString *from = [self standardNameFromViewModel:_currentViewController.viewModel];
NSString *to = [self standardNameFromViewModel:nextViewModel];
// We are going to try and find a segue to go to the next viewModel. The way segues are named
// in our storyboard should be: FromModel::ToModel
// 1. try Segue method. For example, a segue going from WelcomeViewController to LoginViewController would be named "Welcome::Login"
// 2. If a segue is not found, try to instantiate the view controller and push it directly. We look up the view controller by its stripped model name (i.e. "WelcomeViewModel" -> "Welcome")
// 3. If the view controller is not found in the storyboard, try a XIB with the stripped model name.
