title: Change the colour of the text UITextField to the colour typed in it
body: <p>I have a <code>UITextView</code> and I need to detect the <code>String</code> which will be a colour that the user has typed in it. Then I need to change the colour of the text in the <code>UITextField</code> to the colour typed by the user.</p>
  
  <p>For example: if I type 'red' in the <code>textField</code>, the colour of the text should change to red.</p>
  
  <p>Does anyone know how this can be done?</p>
  
  <p>Thanks!</p>
