Split View App with Multiple Detail Views - uisplitviewcontroller

Question

I'm trying to create a split view app with multiple detail view controllers. I'm having trouble with the basic setup/skeleton of the app. First I tried using xcode's Master-Detail Application template. The problem is that the classes from the template look something like this:
MasterViewController.h
MasterViewController.m
DetailViewController.h
DetailViewController.m
But what I want is something like this:
MasterViewController.h
MasterViewController.m
TitleViewController.h
TitleViewController.m
DateViewController.h
DateViewController.m
...
I can't figure out how to get my view controllers to load when user selects a new row.
I also tried using the sample MultipleDetailViews app from Apple, but the sample app has multiple issues for me including the fact that it uses nib files, which I don't want.
Can anyone help? Is there some tutorial about how to set up a split view app with multiple detail view controllers (without nibs)? Thank you!

Thanks! Could you post the link for the BigNerdRanch one? I couldn't find it. Also, I couldn't follow the Raywenderlich one because it uses an older version of xcode. Following your sample project, I think I'm close, but I'm getting a "terminating with uncaught exeption...". Here's what I did:
Create new project from Master-Detail template.
Add files MyTableViewController.h and MyTableViewController.m.
In MasterViewController.m, set the number of sections to 1 and the number of rows to 2.
In MasterViewController.h add property "MyTableViewController *myTableViewController".
(When user clicks 1st row, detailViewController should show, when he clicks 2nd row, myTableViewController should show.)
In MasterViewController.m, change didSelectRowAtIndexPath to:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
int row = [indexPath row];
if( row == 0 ) {
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:self.detailViewController];
NSArray *vcs = [NSArray arrayWithObjects:[self navigationController],nav, nil];
[[self splitViewController] setViewControllers:vcs];
}
else {
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:self.myTableViewController];
NSArray *vcs = [NSArray arrayWithObjects:[self navigationController],nav, nil];
[[self splitViewController] setViewControllers:vcs];
}
}
The project runs, but when I click on the 2nd row (row == 1) I get the exception.
*update 2
- (void) tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath {
int row = [indexPath row];
AppDelegate *delegate = [[UIApplication sharedApplication] delegate];
UINavigationController *detailNav = [delegate.splitController.viewControllers objectAtIndex: 1];
NSArray *viewControllers = nil;
switch (row) {
case 0:
viewControllers = [[NSArray alloc] initWithObjects: delegate.dateController, nil];
break;
case 1:
viewControllers = [[NSArray alloc] initWithObjects: delegate.repeatController, nil];
default:
break;
}
[delegate.splitController removeFromParentViewController];
detailNav.viewControllers = viewControllers;
[delegate.window addSubview: delegate.splitController.view];
}

There's actually a great tutorial by the BigNerdRanch on how to use UISplitViewControllers. Honestly, there's no difference between using them to push a different UIViewController as the Detail or Master viewController. They just need a reference to one another and when an event happens, you push a new viewController to one side or the other. I've attached a sample project below for you to reference.

So the following happenins inside a UITableViewController which is the MasterViewController.
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
// 1. get the controllers from the split view [master, detail]
let controllers = split.viewControllers
// 2. get nav controller for the detail + the current storyboard
let navigationController = controllers[controllers.count-1] as!
let storyboard = UIStoryboard(name: "Main", bundle: nil)
// 3. create the appropriate view controller (vc) then just replace the navigation controllers root vc with your new one using 'navigationController.setViewControllers([vc] ...'
switch indexPath.row {
case 1:
let vc = storyboard.instantiateViewController(withIdentifier: "DetailTableViewController") as! DetailTableViewController
navigationController.setViewControllers([vc], animated: false)
case 2:
let vc = storyboard.instantiateViewController(withIdentifier: "DetailCollectionViewController") as! DetailCollectionViewController
navigationController.setViewControllers([vc], animated: false)
default:
let vc = storyboard.instantiateViewController(withIdentifier: "DetailViewController") as! DetailViewController
navigationController.setViewControllers([vc], animated: false)
break
}
}
You can do the same thing with segues. From the MasterViewController in the storyboard, drag a segue to a navigation controller and set the segue kind as a 'Show Detail (e.g. replace)'. Then from there in you didSelectRowAt you can call performSegue with identifier. Make sure that your segue has an 'Identifier'
