检测scrollToRow函数的结束

Question

如何在tableview中检测scrollToRow函数的结束？我试图实现scrollViewDidEndScrollingAnimation函数，但是当scrollToRow结束时它不会被调用。

Answer 1

您应该将代理添加到Scrollview：

override func viewDidLoad() 
{        
    super.viewDidLoad()  
    self.scrollview.delegate = self
}

Answer 2

 func scrollViewDidScroll(_ scrollView: UIScrollView) {
    let  height = scrollView.frame.size.height
    let contentYoffset = scrollView.contentOffset.y
    let distanceFromBottom = scrollView.contentSize.height - contentYoffset
    if distanceFromBottom < height {
        print(" you reached end of the table")
    }
}
