class CustomerController: BaseViewController {
override func viewDidLoad() {
super.viewDidLoad()
setupUI（）
}
override func setupUI() {
let scrollView = UIScrollView(frame: self.view.bounds)
scrollView.isScrollEnabled = true
scrollView.contentSize = CGSize(width: UIScreen.cz_screenWidth(), height: UIScreen.cz_screenHeight()*2)
scrollView.showsHorizontalScrollIndicator = false
scrollView.showsVerticalScrollIndicator = true
scrollView.scrollsToTop = true
self.view.addSubview(scrollView)
}
」
代码如上，结果显示的时候竟然出现scroll滚动之后，背景里面还有未滚动的样子，傻眼了，差了几小时才记起来在父Controller里面已经吊用了setupUI方法，这里super后重复调用了setupUI导致此bug，回去抽自己个嘴巴。。。。
