How to disable UITextField editing but still accept touch?

Question

I\'m making a UITextField that has a UIPickerView as inputView. Its all good, except that I can edit by copy, paste, cut and select te

Answer 1

In Swift:

func textFieldShouldBeginEditing(textField: UITextField) -> Bool {
    questionField.resignFirstResponder();
    // Additional code here
    return false
}

Answer 2

To prevent editing of UITextField while using UIPickerView for selecting values(in Swift):

self.txtTransDate = self.makeTextField(self.transDate, placeHolder: "Specify Date")
self.txtTransDate?.addTarget(self, action: "txtTransDateEditing:", forControlEvents: UIControlEvents.EditingDidBegin)

func makeTextField(text: String?, placeHolder: String) -> UITextField {
    var textField = UITextField(frame: CGRect(x: 140, y: 0, width: 220.00, height: 40.00));
    textField.placeholder = placeHolder
    textField.text = text
    textField.borderStyle = UITextBorderStyle.Line
    textField.secureTextEntry = false;
    textField.delegate = self
    return textField
}


func txtTransDateEditing(sender: UITextField) {
    var datePickerView:UIDatePicker = UIDatePicker()
    datePickerView.datePickerMode = UIDatePickerMode.Date
    sender.inputView = datePickerView
    datePickerView.addTarget(self, action: Selector("datePickerValueChanged:"), forControlEvents: UIControlEvents.ValueChanged)
}

func datePickerValueChanged(sender: UIDatePicker) {
    var dateformatter = NSDateFormatter()
    dateformatter.dateStyle = NSDateFormatterStyle.MediumStyle
    self.txtTransDate!.text = dateformatter.stringFromDate(sender.date)
}

func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool  {
    self.resignFirstResponder()
    return false
}

This workaround works. Put a transparent UIView above the text field and implement the following code:

- (void)viewDidLoad
{
 [super viewDidLoad];

   UILongPressGestureRecognizer *press = [[UILongPressGestureRecognizer alloc]             initWithTarget:self action:@selector(longPress)];
[transparentView addGestureRecognizer:press];
 [press release];
  press = nil;
}

-(void)longPress
{
   txtField.userInteractionEnabled = NO;
}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
   txtField.userInteractionEnabled = YES;
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
  [txtField becomeFirstResponder];
}
