UISegmentedControl, UIToolbar y UINavigationItem

Question

He creado un UISegmentedControl y lo he adjuntado correctamente a mi navigationItem.tableView.

Pero cuando intento adjuntarlo a una UIToolbar, explota.

Estoy seguro de que he visto UISegementedControls en barras de herramientas antes, pero parece que no funciona. ¿Pensamientos?

// works 
NSArray *statusItems = [[NSArray alloc] initWithObjects:@"one", @"two", nil]; 
statusSegments_ = [[UISegmentedControl alloc] initWithItems:statusItems]; 
self.navigationItem.titleView = statusSegments_; 

// doesn't work 
NSArray *statusItems = [[NSArray alloc] initWithObjects:@"one", @"two", nil]; 
statusSegments_ = [[UISegmentedControl alloc] initWithItems:statusItems]; 
NSArray *toolbarItems = [[NSArray alloc] initWithObjects:statusSegments_, nil]; 
self.toolbarItems = toolbarItems; 
[toolbarItems release];

Usted necesita para dar el punto de vista de control segmentado en un UIBarButtonItem:

UIBarButtonItem *item = [[[UIBarButtonItem alloc] initWithCustomView:statusSegments_] autorelease];
