選擇器輪科羅納未出現在所有

Question

所以我想作一個多輪式裝載機，使得

dataWheel1 = {"Standard", "Inverse Standard", "Hyperbolic", "Inverse Hyperbolic"} 
dataWheel2 = {"Sine", "Cosine", "Tangent", "Secant", "Cosecant", "Cotangent"} 

所以我做到以下幾點：

local storyboard = require("storyboard") 
local scene = storyboard.newScene() 

function scene:createScene(event) 
    local group = self.view 

    local bg = display.newRect(0, 0, display.contentWidth, display.contentHeight) 
    bg:setFillColor(255) 

    local widget = require "widget" 

    local columnData = {} 

    columnData[1] = {"Standard", "Inverse Standard", "Hyperbolic", "Inverse Hyperbolic"} 
    columnData[1].alignment = "right" 
    columnData[1].width = 120 
    columnData[1].startIndex = 7 

    columnData[2] = {"Sine", "Cosine", "Tangent", "Secant", "Cosecant", "Cotangent"} 
    columnData[2].startIndex = 2 

    local picker = widget.newPickerWheel{ 
    id="myPicker", 
    font="Helvetica-Bold", 
    top=258, 
    columns=columnData 
    } 

    group:insert(picker.view) 
    group:insert(bg) 
end 

function scene:enterScene(event) 
    local group = self.view 
end 

function scene:exitScene(event) 
    local group = self.view 
end 

function scene:destroyScene(event) 
    local group = self.view 
end 

scene:addEventListener("createScene", scene) 

scene:addEventListener("enterScene", scene) 

scene:addEventListener("exitScene", scene) 

scene:addEventListener("destroyScene", scene) 

return scene 

這顯示了在模擬器作爲空白頁面。我完全失去了什麼是錯誤的或如何使它正確。

任何幫助將不勝感激，謝謝。

看看這個example。我認爲你需要這個：

local varName = require "widget"
