title: Hide UIActionSheet on iPad
body: <p>I just got a mail from apple that my iPad app was rejected because my 'app contains popover elements that didn't point  to the element that revealed them and more than one popover element visible onscreen at a time'.</p>
  
  <p>The problem is that I call an actionsheet which is still visible when I switch from one view to another and that there can be called to actionsheets at a time. 
  Now I ask myself how I can hide an actionsheet on a view change or when another actionsheet is opend.</p>
