title: How to highlight text in IOS label
body: <p>I'm new to IOS and making a instagram clone to practice IOS development.</p>
  
  <p>I'm interested in one label with highlighted text on instagram's sign in page.</p>
  
  <p><a href="https://i.stack.imgur.com/v9t4n.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/v9t4n.jpg" alt="enter image description here"></a></p>
  
  <p>I have two questions about the screen shot above.</p>
  
  <p>1, My guess it is one label with partial text is highlighted.</p>
  
  <p>2, Only after user tap on the highlighted part, it will trigger action to move to another page.</p>
  
  <p>I googled but couldn't find a way to implement this.</p>
  
  <p>Another guess is this feature is from a third party library.</p>
  
  <p>Do you what library could do something similar?</p>
  
  <p>Thanks</p>
