iphone – How to launch a TTTableView based view with TTLauncherView? – Education Career Blog

I’m very newbie with Three20. I’m trying to make an TTLauncherView based interface, without success for now.

My LauncherView contains a button, mapped to an URL. When I click on this button, I want a TTTableView based to be displayed on screen. But I have nothing.

Here is a piece of my AppDelegate code :

map from:@"tt://rank" toViewController:RankController class;

And the LauncherView code (a piece, too) :

launcherView.pages = NSArray arrayWithObjects:
                      NSArray arrayWithObjects:
                       TTLauncherItem alloc    
                         canDelete:YES autorelease,nil, nil;

The button is here, no problem. But when clicked, it never opens my RankController class. Here is its source :

    - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
        if (self = super initWithNibName:nibNameOrNil bundle:nibBundleOrNil)
            self.title = @"Rank";
            self.variableHeightRows = YES;

        return self;

- (void)dealloc
    super dealloc;

- (void) createModel
    self.dataSource = TTSectionedDataSource dataSourceWithObjects:
                       TTTableTextItem itemWithText:@"Item n°1" URL:nil,
                       TTTableTextItem itemWithText:@"Item n°2" URL:nil,
                       TTTableTextItem itemWithText:@"Item n°3" URL:nil,
                       TTTableTextItem itemWithText:@"Item n°4" URL:nil,
                       TTTableTextItem itemWithText:@"Item n°5" URL:nil,


I tried to proceed the same way that the examples packaged in Three20, so what am I doing wrong ?

Thanks in advance


You need to implement the TTLauncherViewDelegate.
In your .h file, declare your view controller to implement the TTLauncherViewDelegate:

@interface SFLauncherViewController : TTViewController <TTLauncherViewDelegate>

Then in .m file, implement this method:

- (void)launcherView:(TTLauncherView *)launcher didSelectItem:(TTLauncherItem *)item{
    NSLog(@"did select item: %@", item URL);
    TTNavigator *navigator = TTNavigator navigator;

    TTURLAction *action = TTURLAction actionWithURLPath:item URL applyAnimated:YES;

    navigator openURLAction:action;
