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 ?

thank you for your response Matthias. i want to clarify my first question more. so, i created my data store like this when user launched the app.

// create the datamanager
AGDataManager* dm = [AGDataManager manager];
// add a new (default) store object:
id<AGStore> myStore = [dm store:^(id<AGStoreConfig> config) {
    [config setName:@"tasks"];
    [config setType:@"PLIST"];
}]

then user switched to some other app and my app eventually terminated. then user came back to my app again. how do i retrieve the data store i created above? does this work (seems like it won't, as i lost my data manager above):

// create the datamanager
AGDataManager* dm = [AGDataManager manager];
// add a new (default) store object:
id<AGStore> myStore = [dm storeWithName:@"tasks"]

Hi All,

I am trying out the AeroGear iOS lib, and trying to achieve client side data persistency employing AeroGear as much as possible. Here are a few questions I have, and I would appreciate any comments, suggestions and/or directions:

- So, starting from the basic question, how can I retrieve my data stores once user leaves the app and comes back (or, can I do this at all)?

there are callbacks for the lifecycle of the app

 

-Then, what is the difference between "MEMORY" type data store and "PLIST" type one (especially considering my goal is data persistence)?


MEM -> run of the app;
PList -> property list => pers. storage on the file system (sandbox style)
 

- Or alternatively, considering what AeroGear provides for now, what would be the best approach to implement offline support for the client? (for now, what I know is the lib does not provide DataSync. so data consistency is what I will take care of on my own.)

store PList and use the "Reachability" class (Apple example OR https://github.com/tonymillion/Reachability)

-M

 

Thanks for your time to read (and to respond). Bests,
