title: How do I unfocus UITextFields when user presses other controls/blank space?
body: <p>I have a <code>UITextField</code>. It works normally, meaning that when pressed, it fires <code>EditingDidBegin</code> method etc. The problem is that I cannot deselect it, meaning that the keyboard will be always visible, covering important controls. I thought that default behavior would be deselecting/hiding keyboard when user clicks somewhere different from the <code>UITextField</code>, for example on the empty space around it, but it's not - the <code>UITextField</code> is still there. One option to achieve this behavior would be adding touch listener to everything other than <code>UITextFields</code> and perform manual unfocusing when it fires, but that would be a terrible solution for obvious reasons.</p>
