//config DataProvider. You should 
picker.configDataProvider {[unowned self] (component, parentID, receiver) in
    if component == 0 {
        // load first Component Data from network or local.
        let firstComponentData = self.loadFirstComponentData() 
        // all component data should adopt AsyncDataPickerItemProtocol
        receiver(firstComponentData) 
    } else if component == 1 {
        // load second Component Data from network or local.
        let secondComponentData = self.loadSecondComponentData(firstID: parentID) 
        receiver(secondComponentData)
    }
