    ios - Table View Scroll To Row - Stack Overflow

    programmeradmin3浏览0评论

    Here is my implementation.

    lazy var reviewTV: UITableView = {
    let tv = UITableView()
    
    tv.separatorStyle = .none
    tv.showsVerticalScrollIndicator = false
    tv.rowHeight = UITableView.automaticDimension
    tv.estimatedRowHeight = UITableView.automaticDimension
    tv.backgroundColor = .clear
    tv.contentInset = .zero
    
    tv.dataSource = self
    tv.delegate = self
    
    tv.mj_footer = refreshFooter
    
    tv.register(CombinedViewCell.self, forCellReuseIdentifier: CombinedViewCell.identifier)
    
    return tv
}()

    And

    override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    
    if selectedRow > 0 {
        let indexPath = IndexPath(row: selectedRow, section: 0)
        reviewTV.performBatchUpdates(nil) { [weak self] _ in
            self?.reviewTV.scrollToRow(at: indexPath, at: .top, animated: false)
        }
        
        showGuiderView(from: vm.dataSource[selectedRow].reviewContent)
    }
}

    I'm facing difficulty to scroll to selected index position. My tableview cell height may be over the intended height for 1 content. Suspect due to rendering issues.

    Hope could get help on this, let me know if needed further information or code snippets.
