[aerogear-dev] iOS client side data persistence

[Yavuz Selim YILMAZ]

Hi,

Thanks for the answers. I have another question if you don't mind. When I create the myStore like in your examples, do I have any indication that the store is not empty (i.e. it is loaded from already existing plist store)? I can readAll from the store and check the count, but is there any better way to get it? (maybe a side question, is readAll efficient in this case?)

I appreciate your help. Bests,
