Hide keyboard when scroll UITableView

Question

In my app i want hide keyboard when i start scrolling UITableView. I search about this in internet, and most answer is subclassing UITableView (http://stackoverflow.com/ques

Answer 1

Working solution without writing single line of code in your Controller:

As your question is to handle the hide keyboard with one condition only (on scroll). But here I am recommending one solution to handle textfield and keyboard together which works like charm for UIViewController, UITableView and UIScrollView. The interesting fact is that You do not need to write any single line of code.

Answer 2

With Swift 5

To hide the keyboard when scrolling the TableView and stop editing properly, we still need to combine two types of answers:

1. Set the keyboard dismiss mode in IB (as Kyle explained) or in ViewDidLoad() code (as Pei explained) for instance:

tableView.keyboardDismissMode = .onDrag

2. Force the current textfield to resign as first responder (as in Vasily's answer). We just need to add the following to our UITableViewController class

    override func scrollViewDidScroll(_ scrollView: UIScrollView) {
        if !tableView.isDecelerating {
            view.endEditing(true)
        }
    }

Answer 3

Not sure why you need to subclass UITableView for this.

In the view controller that contains the plain UITableView, try adding this:

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView
{
    [searchBar resignFirstResponder];
}

Solution

func scrollViewDidScroll(_ scrollView: UIScrollView) {
    if !tableView.isDecelerating {
        view.endEditing(true)
    }
}

Full Sample

ViewController

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var tableView: UITableView!
    @IBOutlet weak var searchBar: UISearchBar!


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

// MARK: - UITableViewDataSource

extension ViewController: UITableViewDataSource {

    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 100
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell =  UITableViewCell(style: .subtitle, reuseIdentifier: nil)
        cell.textLabel?.text = "Title"
        cell.detailTextLabel?.text = "\(indexPath)"
        return cell
    }
}

// MARK: - UITableViewDelegate

extension ViewController: UITableViewDelegate {

    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        if !tableView.isDecelerating {
            view.endEditing(true)
        }
    }
}

Result

Answer 5

You can do this right in Interface Builder. Select your UITableView and open the Attributes Inspector. In the Scroll View section set the Keyboard field to Dismiss on Drag.

Answer 6

Just to add an update to the answers above. The below worked for me in Swift 1.2

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissMode.OnDrag

or

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissMode.Interactive
