如何簡化在日冕中加載一些文件？

Question

我是新來的電暈，所有的工作都是從別人的抓起。讓我看看，我有3張圖片，標題爲shop1price shop2price shop3price。現在，我希望它被簡化爲下面的代碼

local options = 
{ 
    { defaultFile = 'images/shop1price.png' }, 
    { defaultFile = 'images/shop2price.png' }, 
    { defaultFile = 'images/shop3price.png' }, 
} 

local priceTag = {} 
for i = 1,3 do 
    priceTag[i] = widget.newButton{ 
     options[i], 
     overColor = {128,128,128,255}, 
     width = 73, 
     height = 38, 
     left = (centerX-155) + (i-1)*118, 
     top = centerY * 0.88, 
     id = i, 
     onEvent = function (e) 
      if e.phase == 'ended' then 
       onTouchBuy(e.target.id) 
      end 
      return true 
     end 
    } 
    -- priceTag[i] : setReferencePoint(display.CenterReferencePoint) 
    priceTag[i] : scale(0.8 , 0.8) 
    buttonGroup : insert(priceTag[i]) 
end 

但按鈕沒有出現，我認爲錯在options[i]。但問題總是我不知道怎樣纔是正確的。我知道我可以一個接一個地編碼，但肯定很累。如果我有例如100個按鈕怎麼辦？

任何幫助，將不勝感激。

local options = {} 

    [#options+1] = 'images/shop1price.png' 
    [#options+1] = 'images/shop2price.png' 
    [#options+1] = 'images/shop3price.png' 


local priceTag = {} 
for i = 1,#options do 
    priceTag[i] = widget.newButton{ 
     defaultFile = options[i], 
     overColor = {128,128,128,255}, 
     width = 73, 
     height = 38, 
     left = (centerX-155) + (i-1)*118, 
     top = centerY*0.88, 
     id = i, 
     onEvent = function (e) 
     if e.phase == 'ended' then 
      onTouchBuy(e.target.id) 
     end 
     return true 
    end 
    } 
    -- priceTag[i] : setReferencePoint(display.CenterReferencePoint) 
    priceTag[i] : scale(0.8 , 0.8) 
    buttonGroup : insert(priceTag[i]) 
end 

試試這個，應該可以正常工作。
