URL navigation in three20

I am fairly new to three20 so bear with me. I have the following code which loads objects to the data source:

- (void)loadView {
    [super loadView];
    self.navigationController.navigationBar.tintColor = [UIColor blackColor];
    RKObjectTTTableViewDataSource* dataSource = [RKObjectTTTableViewDataSource dataSource];
    [dataSource mapObjectClass:[Group class] toTableCellClass:[CCell class]];
    RKObjectLoader* objectLoader = [[RKObjectManager sharedManager] objectLoaderWithResourcePath:@"/groups.j开发者_C百科son" delegate:nil];
    dataSource.model = [RKObjectLoaderTTModel modelWithObjectLoader:objectLoader];
    self.dataSource = dataSource;
}

I have set up a URL map in the appdelegate as follows:

TTNavigator *navigator = [TTNavigator navigator];
    navigator.window = self.window;

    TTURLMap *map = navigator.URLMap;
    [map from:@"tt://topics/(initWithTopicsIndex:)" 
    toSharedViewController:[TopicsViewController class]];

I would like to push another controller when I tap on the cell, how do I do this? Can I do this via the setObject in the TTTableViewCell?

Your item class needs to return the URL you want to navigate to in the URLValue method. URLValue is implemented in a category on NSObject and uses the URLMap to create URL for objects.

If your item is subclass of TTTableLinkedItem, it has a URL property, which is used instead.

Have a look at [TTTableViewController didSelectObject:(id)object atIndexPath:(NSIndexPath*)indexPath]

and [TTTableViewDelegate tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath]
