title: Loading Indicator in Status Bar iOS
body: <p>I'm trying to figure out what the loading circle animation in the status bar is. A lot of apps, when they load data, have a spinner in the status bar to indicate that the app is loading data, but I can't figure out what its called to implement it. Can someone tell me what it is called?</p>
  
  <p>If you don't know what I'm talking about, but have an iOS device, try loading a web page in Safari and look at the spinner in the status bar. Thats what I'm talking about.</p>
