_drupalgap_back_exit and ios app has the iphone's system default top tool bar upon the app
Dear Frankenstein, I wan to report some issues about drupalgap ios app.
1, The_drupalgap_back_exit() function doesn't seem to work on ios app.
2, Within my drupalgap ios app, the IOS system default top toolbar always overlap on my app's user interface.
Can you give me some your advice thank you very much!
IOS default system top toolbar

@xiayangjun If there are two issues that need addressing, please create a separate for each in the future.
no 1. - I'd need someone to use a debug trace on that function to see when/where it fails on a compiled iOS app
no 2. - you need the the iO7 Status Bar plugin, see step 2a mentioned here: http://docs.drupalgap.org/7/Compiling_a_Mobile_Application/Publishing_an_App_for_iOS
@signalpoint thank you for your tip. no 2. solved.
@signalpoint The instructions in tip no.2 no longer work (at least on my app). This sets the status bar from transparent to black, but the statusbar is still overlaying the top menu. Is there some new instructions after some of the latest iOS updates?
@signalpoint please ignore my last comment. It turns out that the admob plugin overwrites the screen size set by the statusbar plugin. There is a setting in the admob plugin to fix the status bar that isn't documented very clearly. All still works appropriately per your instructions if the admob plugin is not used.
