今天開發(fā)在Storyboard頁(yè)面中使用ScrollView，在 viewWillAppear 和 viewDidLoad 中設(shè)置了contentSize無(wú)效

解決辦法：在viewDidAppear設(shè)置contentSize

override func viewDidAppear(_ animated: Bool) {
        scrollView.contentSize = CGSize.init(width: UIScreen.main.bounds.width, height: 800);
        scrollView.isScrollEnabled=true;
        scrollView.showsVerticalScrollIndicator = false;
    }
