how to create any UIViewController from NSString name dynamically iOS7.1 - ios7

Question

I want to create a UIViewController from NSString Name (buttonSelected.viewControllerID), considering class name is the same than storyboardIdentifier how to do that???, currently I have following code for two viewControllers, but I only want to have it in one shot
if ([buttonSelected.typeOfContent isEqualToString:#"AtencionClienteDetalleVC"]) {
if ([[functions removeBlanksFromString:buttonSelected.viewControllerID] isEqualToString:#""]) {
[[[UIAlertView alloc] initWithTitle:#"Notification"
message:[NSString stringWithFormat:#"screen destination must not be empty"]
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil] show];
}
else{
AtencionClienteDetalleVC *viewController = [self.storyboard instantiateViewControllerWithIdentifier:buttonSelected.viewControllerID];
viewController.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:LOGO_COMPANY]];
viewController.itemsCatalog = buttonSelected.viewControllerParameters;
[self.navigationController pushViewController:viewController animated:YES];
}
return;
}
if ([buttonSelected.typeOfContent isEqualToString:#"ListadoVideos"]) {
if ([[functions removeBlanksFromString:buttonSelected.viewControllerID] isEqualToString:#""]) {
[[[UIAlertView alloc] initWithTitle:#"Notification"
message:[NSString stringWithFormat:#"screen destination must not be empty"]
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil] show];
}
else{
ListadoVideos *viewController = [self.storyboard instantiateViewControllerWithIdentifier:buttonSelected.viewControllerID];
viewController.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:LOGO_COMPANY]];
viewController.itemsCatalog = buttonSelected.viewControllerParameters;
[self.navigationController pushViewController:viewController animated:YES];
}
return;
}

Answer 1

just need to set all your buttonSelected.typeOfContent to "ViewController" and then replace your current code for this:
if ([buttonSelected.typeOfContent isEqualToString:#"ViewController"]) {
if ([[functions removeBlanksFromString:buttonSelected.viewControllerID] isEqualToString:#""]) {
[[[UIAlertView alloc] initWithTitle:#"Notification"
message:[NSString stringWithFormat:#"screen destination must not be empty"]
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil] show];
}
else{
NSString *myUIViewControllerClassName = buttonSelected.viewControllerID;
Class myClass = NSClassFromString(myUIViewControllerClassName);
NSObject *myObject = [myClass new];
if( [myObject isKindOfClass:[UIViewController class]] ){
UIViewController *rightViewController = (UIViewController *) myObject;
rightViewController = [self.storyboard instantiateViewControllerWithIdentifier:myUIViewControllerClassName];
rightViewController.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:LOGO_COMPANY]];
[self.navigationController pushViewController:rightViewController animated:YES];
}
}
return;
}
