如何從SWIFT的結束頁面開始水平滾動視圖

Question

我有一個水平滾動視圖，並且已啓用分頁選項。所以我在3頁「橫向」添加了3個圖像視圖。我希望我的最後一頁首先顯示。即從右端開始。這裏是我的代碼：

self.myScrollView.frame = CGRectMake(0, 0, self.view.frame.width, self.view.frame.height) 

    let scrollViewWidth = self.myScrollView.frame.width 
    let scrollViewHeight = self.myScrollView.frame.height 

    let imgOne = UIImageView(frame: CGRectMake(0, 0, scrollViewWidth, scrollViewHeight)) 
    let imgTwo = UIImageView(frame: CGRectMake(-(scrollViewWidth), 0, scrollViewWidth, scrollViewHeight)) 
    let imgThree = UIImageView(frame: CGRectMake(-(scrollViewWidth)*2, 0, scrollViewWidth, scrollViewHeight)) 

    imgOne.image = UIImage(named: "0") 
    imgTwo.image = UIImage(named: "1") 
    imgThree.image = UIImage(named: "2") 

    self.myScrollView.addSubview(imgOne) 
    self.myScrollView.addSubview(imgTwo) 
    self.myScrollView.addSubview(imgThree) 

    self.myScrollView.contentSize = CGSizeMake(scrollViewWidth*3, 0) 

Answer 1

最初設定contentOffset到scrollViewWidth*2將橫向滾動兩頁：

scrollView.contentOffset = CGPointMake(scrollViewWidth*2,0) 

，你可以設置你想要在X值的任何值水平滾動。
