Hiding the Keyboard when losing focus on a UITextView

Question

So I have a UITextView that I\'m using to allow the user to submit some text.

My problem is, I can\'t seem to figure out how to allow the user to \'Cancel\' by tappi

Answer 1

I wanted a version of this that worked for resigning from any view, without requiring specific outlets for each one.. Here is my solution, which I put into one of my standard container views..

It's using MonoTouch C#, though it should be obvious how to convert it to Objective-C

    private void findAndResignFirstResponder(UIView node=null) {
        if (node == null) { return; }
        if (node.IsFirstResponder) {
            node.ResignFirstResponder();
            return;
        }

        foreach (UIView view in node.Subviews) {
            findAndResignFirstResponder(node:view);
        }
    }

    private bool haveDrag = false;
    public override void TouchesEnded(NSSet touches, UIEvent evt) {
        if (!haveDrag) {
            UITouch touch = (UITouch)evt.AllTouches.AnyObject;
            if (!touch.View.CanBecomeFirstResponder) {
                this.findAndResignFirstResponder(this);
                Console.WriteLine("resign");
            }
        }
        base.TouchesEnded (touches, evt);
    }
    public override void TouchesMoved(NSSet touches, UIEvent evt) {
        haveDrag = true;
        base.TouchesMoved (touches, evt);
    }

    public override void TouchesBegan(NSSet touches, UIEvent evt) {
        haveDrag = false;
        base.TouchesBegan (touches, evt);
    }
