Ionic app height extends ipad viewport in portrait mode

I have created an ionic application. When I display it on an ipad2 (8.1) xcode ios simulator, the landscape view fits properly, but in portrait mode, the content’s height extends past the ipad’s viewport size. You have to scroll up/down to see the header and footer (???). I find this same issue appears while using their sample app:

ionic start myApp tabs

Any and all help would be deeply appreciated. Thanks.
