迅速:

tableView.setContentOffset(CGPointZero, animated: true)

这是代码ScrollTableView到顶部编程

迅速:

self.TableView.setContentOffset(CGPointMake(0, 1), animated:true)

可能的行动:

1

func scrollToFirstRow() {
    let indexPath = NSIndexPath(forRow: 0, inSection: 0)
    self.tableView.scrollToRowAtIndexPath(indexPath, atScrollPosition: .Top, animated: true)
}

2

func scrollToLastRow() {
    let indexPath = NSIndexPath(forRow: objects.count - 1, inSection: 0)
    self.tableView.scrollToRowAtIndexPath(indexPath, atScrollPosition: .Bottom, animated: true)
}

3

func scrollToSelectedRow() {
    let selectedRows = self.tableView.indexPathsForSelectedRows
    if let selectedRow = selectedRows?[0] as? NSIndexPath {
        self.tableView.scrollToRowAtIndexPath(selectedRow, atScrollPosition: .Middle, animated: true)
    }
}

4

func scrollToHeader() {
    self.tableView.scrollRectToVisible(CGRect(x: 0, y: 0, width: 1, height: 1), animated: true)
}

5

func scrollToTop(){
    self.tableView.setContentOffset(CGPointMake(0,  UIApplication.sharedApplication().statusBarFrame.height ), animated: true)
}

禁用滚动到顶部:

func disableScrollsToTopPropertyOnAllSubviewsOf(view: UIView) {
    for subview in view.subviews {
        if let scrollView = subview as? UIScrollView {
            (scrollView as UIScrollView).scrollsToTop = false
        }
        self.disableScrollsToTopPropertyOnAllSubviewsOf(subview as UIView)
    }
}

根据需求修改和使用它。

斯威夫特4

  func scrollToFirstRow() {
    let indexPath = IndexPath(row: 0, section: 0)
    self.tableView.scrollToRow(at: indexPath, at: .top, animated: true)
  }

在Swift-3中:

self.tableView.setContentOffset(CGPoint.zero, animated: true)

要在完成时有一个完成，请添加此扩展

// MARK: - UIScrollView

extension UIScrollView {

    /// Animate scroll to top with completion
    ///
    /// - Parameters:
    ///   - duration:   TimeInterval
    ///   - completion: Completion block
    func animateScrollToTop(withDuration duration:  TimeInterval,
                            completion:             @escaping (()->())) {

        UIView.animate(withDuration: duration, animations: { [weak self] in
                self?.setContentOffset(CGPoint.zero, animated: false)
            }, completion: { finish in
                guard finish else {
                    return
                }
                completion()
        })
    }
}

tableView.animateScrollToTop(withDuration: 0.25) { 
    // Finish
}

迅速:

tableView.setContentOffset(CGPointZero, animated: true)
