Calling init method of a UITableViewController instance with Three20's navigation modell

i have a UITableViewController subclass instance called MainTableViewController within a three20 project. the mapping is set up like this:

[map from:@"tt://catalog" toViewController:[MainTableViewController class]];

after updating to xcode 4 and the current three20 v1.0.5. MainTableViewController's init method is not called anymore. Does anyone have a hint how to map to a view controller's init method without a parameter:

@implementation MainTableViewController
- (id)init{

The 开发者_Go百科intro page to three20-style navigation points out the no init case and the paramter case : http://three20.info/article/2010-10-06-URL-Based-Navigation

am i missing something here?

Three20 expects that you use the designated initializer for UIViewControllers:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
