ios - tableView 滚动到底部不显示最后一部分，必须手动滚动，有人知道吗？

Question

我使用了下面的两种方法，它们都有效，但我提到的问题。

扩展 UITableView {

func scrollToBottom() {
    let sections = numberOfSections-1
    if sections >= 0 {
        let rows = numberOfRows(inSection: sections)-1
        if rows >= 0 {
            let indexPath = IndexPath(row: rows, section: sections)
            DispatchQueue.main.async { [weak self] in
                self?.scrollToRow(at: indexPath, at: .bottom, animated: true)
            }
        }
    }
}

func moveToLastComment() {
    if self.contentSize.height > self.frame.height {
        let lastSectionIndex = self.numberOfSections - 1 
        let lastRowIndex = self.numberOfRows(inSection: lastSectionIndex) - 1 
        let pathToLastRow = NSIndexPath(row: lastRowIndex, section: lastSectionIndex)[enter image description here][1]  
        self.scrollToRow(at: pathToLastRow as IndexPath, at: UITableViewScrollPosition.bottom, animated: true)
    }
}

使用这个方法

 self.tableView.setContentOffset(CGPoint(x: 0, y: CGFLOAT_MAX), animated: true)
