How to add MBSwitch as Bar Button Item

[bhartsb]

How would one add MBSwitch as or into a Bar Button Item in the navigation bar? I've so far been unable to do this.

Seems to do it: UIBarButtonItem *switchButtonBarItem = [[UIBarButtonItem alloc]initWithCustomView:_filterSwitch]; NSArray * a = [self.navigationItem.leftBarButtonItems arrayByAddingObject:switchButtonBarItem]; self.navigationItem.leftBarButtonItems = a;
