[aerogear-dev] iOS client side data persistence

[Matthias Wessendorf]

Yes,

here is an simple example:

https://gist.github.com/matzew/80ef7d756c15ca774907

Run a simple app like that in Xcode:

1) in "application:didFinishLaunchingWithOptions" we create the
(persistent) PList store
2) once the app becomes "active",the "didFinishLaunch" log statement shows
an empty store (surprise :))
2a) Afterwards, we save some values into the store (note:
the entry requires @"id" as it's field...).
3) Now, on your phone, kill the iOS app (see [1] if not sure how to do that)
4) start the app, via Xcode, again - and see the "didFinishLaunch" log
statement now shows the values, we stored before on the "
applicationDidBecomeActive" delegate function.


Do you think we should be more clear on this in our docs ?
