 iOS 7.1 Cordova with AND without viewport height DOES resize, DOES NOT fire resize event
 iOS 7.1 Safari with AND without viewport height DOES NOT resize

 iOS 7.0 Cordova with viewport height DOES resize, DOES fire resize event
 iOS 7.0 Cordova without viewport height DOES resize, DOES NOT fire resize event
 iOS 7.0 Safari with AND without viewport height DOES NOT resize

 iOS 6.1 Cordova with AND without viewport height DOES NOT resize
 iOS 6.1 Safari without viewport height DOES NOT resize

 NOTES:
   - iOS 7.1 Safari with viewport height screws up ionic layout
   - iOS 7.0 Safari with viewport height, the scroll view does not resize properly on keyboardhide
   - iOS 7.0 Cordova without viewport height, scroll view does not resize properly switching inputs at bottom of page
   - iOS 6.1 Cordova and Safari don't work well with viewport height
   - If its not a webview, and a viewport height was set, just removing
     the height value doesn't trigger the change, but setting height=0 does the trick

 RECOMMENDATIONS:
   -iOS 7.1 Cordova no viewport height, keyboard is not over webview
   -iOS 7.1 Safari no viewport height, keyboard is over webview

   -iOS 7.0 Cordova yes viewport height, keyboard is not over webview
   -iOS 7.0 Safari no viewport height, keyboard is over webview

   -iOS 6.1 Cordova no viewport height, keyboard is over webview
   -iOS 6.1 Safari no viewport height, keyboard is over webview
