問(wèn)題.png

問(wèn)題分析: 由于在Storyboard中布局時(shí), 選擇是特定機(jī)型進(jìn)行的布局, 所以在加載時(shí)如果加載到與storyboard中的機(jī)型不一致的手機(jī)上會(huì)出現(xiàn)frame異常的情況(可以在scrollView所在的vc的viewDidLoad方法中打印一下scrollView的frame)

解決方案: 在viewDidLayoutSubviews方法中重置一下 view 的frame

override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        let width = UIScreen.main.bounds.width
        let height = scrollView.bounds.height
        scrollView.contentSize = CGSize(width: width * 3, height: height)
        let subs = scrollView.subviews
        for (i, view) in subs.enumerated() {
            view.frame = CGRect(x: CGFloat(i) * width, y: 0, width: width, height: height)
        }
    }

附加問(wèn)題: scrollView的滾動(dòng)異常, 同時(shí)可以沿任意方向滾動(dòng)

解決方案: 設(shè)置一下scrollView的contentSize, 如果沿x軸滾動(dòng), width值大, 如果沿y軸滾動(dòng), height值大
