Prevent user from setting cursor position on UITextField

Question

I have an UITextField constructed using the storyboard. I want to not allow the user to change the position of the cursor and keep it always at the end of the text into the

Answer 1

Simply create a subclass of UITextField and override the closestPositionToPoint method:

- (UITextPosition *)closestPositionToPoint:(CGPoint)point{
    UITextPosition *beginning = self.beginningOfDocument;
    UITextPosition *end = [self positionFromPosition:beginning offset:self.text.length];
    return end;
}

Now the user will be unable to move cursor, it will be always in the end of field.

SWIFT:

override func closestPosition(to point: CGPoint) -> UITextPosition? {
    let beginning = self.beginningOfDocument
    let end = self.position(from: beginning, offset: self.text?.count ?? 0)
    return end
}
