ios - resignFirstResponder and endEditing (even global calls) are not hiding the keyboard -

i have viewcontroller set delegate uitextfield. no matter try, can not keyboard hide when calling textfieldshouldreturn.

my viewdidload method:

override func viewdidload() {     super.viewdidload()     self.view.addsubview(newmodelfield)     newmodelfield.delegate = self     self.presettableview.registerclass(uitableviewcell.self, forcellreuseidentifier: "presetcell")     //self.view.becomefirstresponder() } 

and textfieldshouldreturn method:

func textfieldshouldreturn(textfield: uitextfield) -> bool {      //uiapplication.sharedapplication().sendaction("resignfirstresponder", to:nil, from:nil, forevent:nil)     if(textfield.text! != ""){         items.append(textfield.text!)         presettableview.reloaddata()         textfield.text! = ""         //self.view.resignfirstresponder()         //self.addview.resignfirstresponder()         //textfield.endediting(true)         //self.view.endediting(true)         uiapplication.sharedapplication().delegate?.window?!.endediting(true)         return false     }     return true } 

you can see commented out attempts have tried whole host of different fixes. know textfieldshouldreturn being called after debugging print statements. can not figure out why keyboard won't hide.

i tried swapping return true , false statements. tried setting delegate storyboard. tried deleting textfield storyboard, cleaning, , adding in. tried top level calls resignfirstresponder , endediting calls these functions textfield , view.

to dismiss keyboard, send resignfirstresponder message text >field first responder. doing causes text >field object end current editing session (with delegate >object’s consent) , hide keyboard.

yourtextfield.resignfirstresponder()
