title: Textfield does not show Keyboard on iOS Simulator
body: <p>I'm trying to build a simple login screen here using basic Textfields, but I can't get a keyboard to appear in the Simulator.<br>
  Input via the physical keyboard works just fine, but in the iOS Simulator there is no keyboard visible. Do I have to explicitly open it or something?</p>
  
  <p>Feels like I'm missing something really basic here.</p>
  
  <pre><code>buildLoginScreen() {
  return new Container(
    padding: EdgeInsets.only(left: 50.0, right: 50.0),
    child: new Column(
      children: &lt;Widget&gt;[
        new TextField(
          style: new TextStyle(color: Colors.white),
          autofocus: true,
          autocorrect: false,
          decoration: new InputDecoration(
            labelText: 'Login',
          ),
          onChanged: (text) { _userLoginEmail = text; },
        ),
        new TextField(
          autofocus: false,
          autocorrect: false,
          obscureText: true,
          decoration: new InputDecoration(
            labelText: 'Password'
          ),
          onChanged: (text) { _userLoginPassword = text; },
        )
      ],
    ),
  );
  }
  </code></pre>
  
  <p><strong>Solution</strong>
  Turns out if the hardware keyboard is connected, it will suppress the software keyboard. <em>cmd + shift + k</em> disconnects the hardware keyboard or <em>cmd + k</em> toggles the software keyboard.</p>
