SRCoreDataStack is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "SRCoreDataStack"To run the example project, clone the repo, and run pod install from the Example directory first.
Get the default shared instance:
self.dataStack = [SRCoreDataStack defaultStackForDataModel:@"Example"];
Save objects coming from network call into Core Data:
[self.dataStack saveObjects:wireObjects deleteNonMatchingLocals:NO inEntity:@"Movie" withWireAttribute:@"id" andLocalAttribute:@"movie_id" andConfiguration:^NSManagedObject *(NSDictionary *obj, NSManagedObject *mo, NSManagedObjectContext *currentCtx) {
Movie *movie = (Movie*)mo;
movie.movie_id = obj[@"id"];
movie.movie_title = obj[@"title"];
movie.movie_description = obj[@"description"];
// define its parent-child relationship
NSMutableArray *ma = [NSMutableArray array];
for (NSString *genreString in obj[@"genres"])
{
MovieGenre *movieGenre = [MovieGenre insertNewObjectIntoContext:currentCtx];
movieGenre.genre_name = genreString;
[ma addObject:movieGenre];
}
movie.movie_genres = [NSSet setWithArray:[NSArray arrayWithArray:ma]];
return movie;
}];
Example project uses this backend project. The backend project, once downloaded and run on Terminal, can be viewed through browser. You can then make seamless live synching between the apps.
- Saves wire objects in background managed object context
- Custom object serialization and relationship management between objects handled within a block
- Under the hood works with NSManagedObject instances, thus the stack doesn't need to know of your custom managed object type
- Uses nested managed object contexts for synching
- Implements "insert or update" algorithm discussed in WWDC 2013-211 video
