Calling dictionary keys using another array

I have a UIPickerView showing data from an Array of keys.

var pokemonData = ["Nidoran", "Clefairy", "Spearow", "Ivysaur", "Gengar", "Arcanine", "Gyarados", "Onix", "Pikachu", "Vaporeon"]

Also I have this Dictionary, but i want call each key to it shows in a label whenever i choose something on the picker.

var typeData = [

    "Nidoran" : "Type: Poison",
    "Clefairy" : "Type: Normal",
    "Spearow" : "Type: Normal, Flying",
    "Ivysaur" : "Type: Grass, Poison",
    "Gengar" : "Type: Ghost, Poison",
    "Arcanine" : "Type: Fire",
    "Gyarados" : "Type: Water, Flying",
    "Onix" : "Type: Rock, Ground",
    "Pikachu" : "Type: Electric",
    "Vaporeon" : "Type: Water"

]

How can I do that? I use this picker function to change the labels

func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

    pokeLabel.text = pokemonData[row]

}

My second label is...

@IBOutlet weak var typeLabel: UILabel!
Solution

  • Just use that typeData Dictionary to get value for selected key.

    func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
     pokeLabel.text = pokemonData[row]
     typeLabel.text = typeData[pokemonData[row]]
}
