UIPanGesture 左右工作而不是快速上下工作

Question

我正在构建一个游戏，其中包含 7 x 7 网格和 3 x 7 侧网格（7 x 7 的东北、南和西）的卡片。 我想使用 pangesture 滚动侧面的卡片，但现在在右侧添加卡片会导致 pangesture 在两侧工作，但不能在顶部或底部工作。 “arrayAllCards.append(button)”行使其不适用于南北。

for j in 0...6{
            for i in 0...3 {

                var cardPos: [Int] = []
                cardPos.append(j)
                cardPos.append(7+i)
                
                var button = Card(suitRank: arrayShuffle[(i+1)*(j+1)].suitRank,
                                  position: cardPos,

问题在于平移手势中的数组大小。

let value1 : Int = Int(arrayAllCards[133].center.y) was needed instead of arrayAllCards[90]. I was not accounting for the extra created cards.
