TTNavigation Passing data

Question

This issue seems as if it is very hard to explain so I shall try my best.

I have several user profiles. I want them to be all handled by the same class.

TT://User/1
TT://User/2

How can I map it in a why were those both push to the user class.

In addition to that how can I tell user class what user ID to pull.

First, you need to map URLs to controllers. You typically do this in the AppDelegate since you want to have the URL map set up before calling a URL to display a view.

Instantiate a TTNavigator
Map the URLs to the controllers via TTURLMap
Always start with a wildcard URL ie. * and map it to a default view controller like TTWebController (the web browser view controller)
Basically, there are 2 types of URL: 1) URL without parameters and 2) URL w/ parameters. For the former, when URL is invoked, the initWithNibName:bundle: "constructor" of the mapped view controller will be called. For the latter, you can indicate what "init" method to call in the TTURLMap. See example below.
Actually opens an URL via openURLAction: method.

Here's the code.

@implementation AppDelegate

- (void)applicationDidFinishLaunching:(UIApplication *)application {
  TTNavigator* navigator = [TTNavigator navigator];

  TTURLMap* map = navigator.URLMap;

  // This is the default map. * = wildcard, any URL not registered will be
  // routed to the TTWebController object at runtime.  
  [map from:@"*" toViewController:[TTWebController class]];
  [map from:@"tt://catalog" toViewController:[CatalogController class]];
  [map from:@"tt://user/(initWithId:)" 
toViewController:[MyUserViewController class]];
  [map from:@"tt://user/(initWithId:)" 
toViewController:[MyUserViewController class]];

  if (![navigator restoreViewControllers]) {   
    [navigator openURLAction:[TTURLAction actionWithURLPath:@"tt://catalog"]];    
  }
}

// ...

@end

Second, subclass a TTViewController

@implementation MyUserViewController

- (id) initWithId:(NSNumber *)index {
  if (self = [super initWithNibName:nibName bundle:nil]) {
    // Do your initialization here.

    // Get the index from a singleton data manager containing the "model."
  }

  return self;
}

@end

Third, navigate to the URL from anywhere in the app.

// Navigate to the URL.
[[TTNavigator navigator] openURLAction:[TTURLAction actionWithURLPath:@"tt://user/1"]];
