Swift Cocoa Osx應用程式ImageViews

Question

我目前正在做一個快速的可可osx項目。 在我的項目中，我有31個NSimageViews，分別命名為space0，space1，space2到space30。 每個圖像視圖都有3個可能的圖像，綠色圖像，藍色圖像和白色圖像。 在不寫出每種可能的情況的情況下，將變量分配給特定圖像視圖的最有效方法是什么。 例如，如果變量x = 10，我想給space10分配一個圖像，如果變量y = 20，給space20分配一個圖像。 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 ==  18 {return space18.image!}

    if imgNumber ==  30 {return space30.image!}
    return nil
