SSDataKit

There is a lot of boilerplate code required to write a Core Data application. This is annoying. In pretty much everything I’ve written since Core Data came to iOS, I have used the following class.

What’s Included

SSManagedObject

• Manages main context, persistent store, etc
• Accessing entity descriptions
• Reflection
• Easy creating and deleting

SSRemoteManagedObject

• Easily find or create objects by a remote ID
• Unpack NSDictionary’s into your Core Data object’s attributes

Example

This is very simple example of how to use SSRemoteManagedObject.

Post.m

- (void)unpackDictionary:(NSDictionary *)dictionary {
  [super unpackDictionary:dictionary];
  self.title = dictionary[@"title"];
}

Now you can create and find posts easily.

Post *post = [Post objectWithDictionary:@{@"id": @(1), @"title": @"Hello World"}];
Post *anotherPost = [Post objectWithRemoteID:@(1)];
NSLog(@"Equal: %i", [post isEqual:anotherPost]); // Equal: 1
