Prevent editing of text in UITextField and hide cursor/caret/magnifying glass while using an inputView

Question

How do I prevent the editing of text in a UITextField along with hiding the cursor/caret/magnifying glass, but still present the keyboard, as I am using an inputView with a UIPickerView/UIDatePickerView?

Setting userInteractionEnabled to NO does not work, because it no longer receives any touches and will not present the keyboard.

Subclass UITextField

//Disables caret
- (CGRect)caretRectForPosition:(UITextPosition *)position
{
    return CGRectZero;
}

//Disables magnifying glass
-(void)addGestureRecognizer:(UIGestureRecognizer *)gestureRecognizer
{
    if ([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]])
    {
        gestureRecognizer.enabled = NO;
    }
    [super addGestureRecognizer:gestureRecognizer];
}

In your UITextFieldDelegate

//Prevent text from being copied and pasted or edited with bluetooth keyboard.
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    return NO;
}

Now just set your text programmatically from the result of your UIPickerView/UIDatePicker.

There are no gesture recognizers (iOS 8): (lldb) po [textField gestureRecognizers] -> nil — Adam Kaplan, Dec 28 '15 at 20:27

Hiding the cursor is a lot simpler in iOS 7. Still need some trickery to disable the loupe

textField.tintColor = [UIColor clearColor];

Still don't know why setting tintColor from storyboard not takes effect, although the code does. – samthui7 Nov 03 '16 at 03:13

I hope this will helpful for you.

Set cursor UIColor -> Empty. In UI, it will be hidden.

[[self.textField valueForKey:@"textInputTraits"] setValue:[UIColor clearColor] forKey:@"insertionPointColor"];

is this a official way to this? I think this is a manipulation of apple's private API. – Carmen Sep 20 '13 at 15:02
This looks suspicious to me! Use Walapu's answer. – Adam Waite Oct 29 '13 at 16:01

I found the best solution was

- (CGRect) caretRectForPosition:(UITextPosition*) position
{
    return CGRectZero;
}

- (NSArray *)selectionRectsForRange:(UITextRange *)range
{
    return nil;
}

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
    if (action == @selector(copy:) || action == @selector(selectAll:) || action == @selector(paste:))
    {
        returnNO;
    }

    return [super canPerformAction:action withSender:sender];
}

This works, but you can still click and type into the textField unless you also implement **textField:shouldChangeCharactersInRange:replacementString:** as per Walapu's answer. — Brett Donald, Mar 17 '15 at 01:29

To have a UITextField without interaction, but still work with an inputView:

Subclass UITextField with these methods:

// Hide the cursor
- (CGRect)caretRectForPosition:(UITextPosition*)position
{
    return CGRectZero;
}

// All touches inside will be ignored
// and intercepted by the superview
- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
{
    return NO;
}

The last method will single-handedly prevent any editing and the magnifier glass, as you won't be able to tap the UITextField.

This works great if you're using a textfield in a UITableViewCell for example, and then can toggle firstResponder status through tableView:didSelectRowAtIndexPath:.

To disable any interaction with textfield except for making it a first responder you can just place a UIButton of the same size right over the textfield. Code for button tap event could be something like this:

- (IBAction)btnEditPhoneTapped:(id)sender
{
    if (self.tfClientPhoneNo.isFirstResponder == NO) [self.tfClientPhoneNo becomeFirstResponder];
}
