body: <p>Having a problem when i try to add a button in a annotation.</p>
  
  <p>Before i've asked this question i've searched for answers on the following pages:
  <a href="https://stackoverflow.com/questions/28225296/how-can-i-add-a-button-to-mkpointannotation">How to add a button to the MKPointAnnotation?</a>
  , <a href="https://stackoverflow.com/questions/29610286/adding-a-button-to-mkpointannotation">Adding a button to MKPointAnnotation?</a>
  etc.
  But all couldn't help me.</p>
  
  <p>This what is tried to do:</p>
  
  <pre><code>var annotation1 = MKPointAnnotation()
  annotation1.setCoordinate(locationKamer1)
  annotation1.title = "Title1"
  annotation1.subtitle = "Subtitle1"
  // here i want to add a button which has a segue to another page.
  mapView.addAnnotation(annotation1)
  </code></pre>
  
  <p>Don't know if what i try to do isn't working. 
  I'm experimenting with swift for the first time.</p>
  
  <p>Hope someone can help me :)</p>
  
  <p>Thanks in advance!</p>
