How to hide number pad, I'm use Xamarin iOS (C#)
<p>I'm found answer for my question on objective-C, but I'm don't search it in Xamarin iOS.
So I have field where user write phone number, when this field editing appear keyboard, number pad type. But this keyboard don't hide and don't have hide button.</p>
<p>in android application for this problem I use code:</p>
<pre><code>one.Click += delegate
        {
            InputMethodManager imm = (InputMethodManager)GetSystemService(Context.InputMethodService);
            imm.HideSoftInputFromWindow(ulitsa.WindowToken, 0);
        };
</code></pre>
<p>In my iOS app this code don't work.
My code in iOS:</p>
<pre><code>            tel.ShouldReturn = delegate {
            tel.ResignFirstResponder ();

            //tel.ReturnKeyType = UIReturnKeyType.Done;

            return true;
        };
</code></pre>
