Uirefreshcontrol - Beginrefreshing Not Working When Uitableviewcontroller Is Inside Uinavigationcontroller

UIRefreshControl - beginRefreshing not working when UITableViewController is inside UINavigationController

It seems that if you start refreshing programmatically, you have to scroll the table view yourself, say, by changing contentoffset

[self.tableView setContentOffset:CGPointMake(0, -self.refreshControl.frame.size.height) animated:YES];

I would guess the reason for this is that it could be undesirable to scroll to the refresh control when user is in the middle/bottom of the table view?

Swift 2.2 version by @muhasturk

self.tableView.setContentOffset(CGPoint(x: 0, y: -refreshControl.frame.size.height), animated: true)

In a nutshell, to keep this portable add this extension

UIRefreshControl+ProgramaticallyBeginRefresh.swift

extension UIRefreshControl {
    func programaticallyBeginRefreshing(in tableView: UITableView) {
        beginRefreshing()
        let offsetPoint = CGPoint.init(x: 0, y: -frame.size.height)
        tableView.setContentOffset(offsetPoint, animated: true)        
    }
}

UIRefreshControl not showing spiny when calling beginRefreshing and contentOffset is 0

It looks like a bug to me, because it only occures when the contentOffset property of the tableView is 0

I fixed that with the following code (method for the UITableViewController) :

- (void)beginRefreshingTableView {

    [self.refreshControl beginRefreshing];

    if (self.tableView.contentOffset.y == 0) {

        [UIView animateWithDuration:0.25 delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations:^(void){

            self.tableView.contentOffset = CGPointMake(0, -self.refreshControl.frame.size.height);

        } completion:^(BOOL finished){

        }];

    }
}

UIRefreshControl does not work

Move tableView.reloadData() to a place where you can be sure the search() function has completed and returned results. If that is an async function then add a completion handler so that you know when to call reloadData(). Then you could call the function like so:

search {
    dispatch_async(dispatch_get_main_queue()) {
        tableView.reloadData()
    }
}

Or, when you're on Swift 3

DispatchQueue.main.async {...}

UIRefreshControl renders behind UINavigation w/ Large Titles

It looks like you are setting the refresh control after the large navigation has been configured.

Try changing the order to something like this -

  override func viewDidLoad() {
    super.viewDidLoad()

    load()

    configureTableView()
    configureUI()
  }
.......
  func configureTableView() {
    tableView.backgroundColor = .usingHex("fafafa")
    tableView.tableFooterView = .init()
    tableView.contentInsetAdjustmentBehavior = .always
    tableView.refreshControl = .init()
  }

  func configureUI() {
    navigationController?.navigationBar.prefersLargeTitles = true
    navigationItem.title = "Latest content"
  }
