I have a text field to search, with an autocomplete list (UITableView) to show the results. I want to dismiss the keyboard while user clicks outside the textfield, and that works; however it breaks my table interaction(user can clicks one of the results to add a record).

I have tried shouldReceiveTouch (source1, source2) with UIGestureRecognizer, however the function doesn't get called. I have

  • Added UIGestureRecognizerDelegate to ViewController.swift as follow:

    class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate,UIGestureRecognizerDelegate {...}

  • Added UITapGestureRecognizer object into storyboard and linked it to my view

  • Added IBAction function to dismiss the keyboard and linked it to the UITapGestureRecognizer object:

    @IBAction func endEditing(sender: AnyObject) {
    addButton.hidden = true
    autocompleteList.hidden = true
    self.view.endEditing(true)
}

  • Called shouldReceiveTouch:

    func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool {
    println("in shouldReceiveTouch")
    gestureRecognizer.delegate = self
     if (touch.view == autocompleteList){
        println("touching autocomplete list")
        return false
    }
    else{
        println("touching elsewhere")
        return true
    }
}

After running the app I learned that shouldReceiveTouch never gets called from the console, so my guess is I didn't set up the delegate correctly; I have been looking here and there for a few hours but still no luck. Other solutions to achieve the same goal are welcome as well. Any help is appreciated! Thanks

    have you set the delegate implementer to your ViewController class in story board? – Sanjay Mohnani Apr 16 '15 at 08:47
  • also please check if the gesture recognizer exist at the top of all other subviews and return false for views which should be excluded from gesture recognizer in shouldReceiveTouch – Sanjay Mohnani Apr 16 '15 at 08:50
  • @SanjayMohnani you saved my day. I didn't set the delegate in the connection inspector. Now it calls the function! Thanks so much – amythegreat Apr 17 '15 at 00:39
