Swift cocoa Osx application imageviews

Question

我目前正在開發一個swift cocoa osx項目。在我的項目中，我有31個NSimageViews，命名爲space0，space1，space2，通過space30。每個圖像視圖有3個可能的圖像，一個綠色圖像，一個藍色圖像和一個白色圖像。根據變量將圖像分配給特定圖像視圖的最有效方式是什麼，而不必寫出每種可能的方案。例如，如果變量x = 10，我想分配空間10圖像，如果變量y = 20，則分配空間20圖像。謝謝

func imgSpace(imgNumber:Int) -> NSImage? { 
    if imgNumber == 0 {return space00.image!} 
    if imgNumber == 1 {return space01.image!} 
    if imgNumber == 2 {return space02.image!} 
    if imgNumber == 3 {return space03.image!} 
    if imgNumber == 4 {return space04.image!} 
    if imgNumber == 5 {return space05.image!} 
    if imgNumber == 6 {return space06.image!} 
    if imgNumber == 7 {return space07.image!} 
    if imgNumber == 8 {return space08.image!} 
    if imgNumber == 9 {return space09.image!} 
    if imgNumber == 10 {return space10.image!} 
    if imgNumber == 11 {return space11.image!} 
    if imgNumber == 12 {return space12.image!} 
    if imgNumber == 13 {return space13.image!} 
    if imgNumber == 14 {return space14.image!} 
    if imgNumber == 15 {return space15.image!} 
    if imgNumber == 16 {return space16.image!} 
    if imgNumber == 17 {return space17.image!} 
    if imgNumber == 18 {return space18.image!} 
    if imgNumber == 19 {return space19.image!} 
    if imgNumber == 20 {return space20.image!} 
    if imgNumber == 21 {return space21.image!} 
    if imgNumber == 22 {return space22.image!} 
    if imgNumber == 23 {return space23.image!} 
    if imgNumber == 24 {return space24.image!} 
    if imgNumber == 25 {return space25.image!} 
    if imgNumber == 26 {return space26.image!} 
    if imgNumber == 27 {return space27.image!} 
    if imgNumber == 28 {return space28.image!} 
    if imgNumber == 29 {return space29.image!} 
    if imgNumber == 30 {return space30.image!} 
    return nil 
} 
let x = 3 
if let myImage = imgSpace(x) { 
    yourOutleT.image = myImage 
} 
let y = 13 
if let myImage = imgSpace(y) { 
    yourOutleT.image = myImage 
} 
let z = 27 
if let myImage = imgSpace(z) { 
    yourOutleT.image = myImage
