So, some of my users don't realize they can hold a cell to get an alert pop-up with options. So, I would like to add some kind of image or text or color - something - to let the user know "hey, you can hold this to get more info." Here is my code below. Any thoughts on the best way to do this?
// handles long press for editing or sharing a search
func tableViewCellLongPressed(
sender: UILongPressGestureRecognizer) {
if sender.state == UIGestureRecognizerState.Began &&
!tableView.editing {
let cell = sender.view as! UITableViewCell // get cell
if let indexPath = tableView.indexPathForCell(cell) {
displayLongPressOptions(indexPath.row)
}
}
}
// displays the edit/share options
func displayLongPressOptions(row: Int) {
// create UIAlertController for user input
let alertController = UIAlertController(title: "Helpful Stuff",
message: "",
preferredStyle: UIAlertControllerStyle.Alert)
// create Cancel action
let cancelAction = UIAlertAction(title: "Cancel",
style: UIAlertActionStyle.Cancel, handler: nil)
alertController.addAction(cancelAction)
let shareAction = UIAlertAction(title: "Share",
style: UIAlertActionStyle.Default,
handler: {(action) in self.shareSearch(row)})
alertController.addAction(shareAction)
presentViewController(alertController, animated: true,
completion: nil)
}
// callback that returns a configured cell for the given NSIndexPath
override func tableView(tableView: UITableView,
cellForRowAtIndexPath indexPath: NSIndexPath) ->
UITableViewCell {
// get cell
let cell = tableView.dequeueReusableCellWithIdentifier(
"Cell", forIndexPath: indexPath) as UITableViewCell
// set cell label's text to the tag at the specified index
cell.textLabel?.text = model.tagAtIndex(indexPath.row)
// set up long press guesture recognizer
let longPressGestureRecognizer = UILongPressGestureRecognizer(
target: self, action: "tableViewCellLongPressed:")
longPressGestureRecognizer.minimumPressDuration = 0.5
cell.addGestureRecognizer(longPressGestureRecognizer)
return cell
}
