@IBOutlet var textFieldItemName: UITextField!
@IBOutlet var textFieldQt: UITextField!
@IBOutlet var textFieldMoreInfo: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
textFieldItemName.delegate = self
textFieldQt.delegate = self
textFieldMoreInfo.delegate = self
}
...
/**
* Called when 'return' key pressed. return NO to ignore.
*/
func textFieldShouldReturn(textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
/**
* Called when the user click on the view (outside the UITextField).
*/
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.view.endEditing(true)
}
}
