            view.backgroundColor = UIColor.gray
            views.append(view)
        }
        
        pickerView.firstselectedItem = 2 // you can also set the first selected item at launch 

    }
    func didSelectIndex(index: Int) {
        print("SelectedIndex \(index)")
    }   
    func numberOfItems() -> Int {
        return 10
    }
    
    func itemForIndex(index: Int) -> UIView {
        return views[index]
    }
