title: phonegap-push-plugin doesn't work in iOS
body: <p>I am having problems with my project. </p>
  
  <p>I have an Ionic Project and I'm using phonegap-plugin-push to send push notifications. 
  On Android works well, but on iOS doesn't work. Do not appears the alert asking if I want to receive notifications and the Registration Event isn't executed.</p>
  
  <p>What is wrong?</p>
  
  <p>Thanks in advance.</p>

  <p>Here is my code:</p>
  
  <pre><code>document.addEventListener('deviceready', function() {
      console.log('&gt;&gt;&gt;&gt;&gt;&gt; DEVICE READY &lt;&lt;&lt;&lt;&lt;&lt;');
      handleNotificationReady();
  });
  
  function handleNotificationReady(){
      console.log('&gt;&gt;&gt;&gt; HandleNotificationReady &lt;&lt;&lt;&lt;');
      var pushNotification;
  
      if (device.platform == 'Android') {
          console.log('&gt;&gt;&gt; Android, nice to meet you!');
          pushNotification = PushNotification.init({
              android: {
                  senderID: '6610***',
                  icon: 'icon'
              }
          });
      } else if (device.platform == 'iOS') {
          console.log('&gt;&gt;&gt; iOS, nice to meet you!');
          pushNotification = PushNotification.init({
              ios: {
                  alert: 'true',
                  badge: 'true',
                  sound: 'true'
              }
          });
      }
  
      pushNotification.on('registration', function(data) {
          console.log('&gt;&gt;&gt;&gt; REGISTRATION &lt;&lt;&lt;&lt;');
          console.log(data.registrationId);
      });
  
      pushNotification.on('notification', function(data) {
          console.log('&gt;&gt;&gt;&gt; NOTIFICATION &lt;&lt;&lt;&lt;');
          console.log(data);
      });
  
      pushNotification.on('error', function(err) {
          console.log('&gt;&gt;&gt;&gt; ERROR &lt;&lt;&lt;&lt;');
          console.log(err);
      });
  }

  <p>Here is my console:</p>
  
  <pre><code>`&gt;&gt;&gt;&gt;&gt;&gt; DEVICE READY &lt;&lt;&lt;&lt;&lt;&lt;
  &gt;&gt;&gt;&gt; HandleNotificationReady &lt;&lt;&lt;&lt;
  &gt;&gt;&gt; iOS, nice to meet you!`
