saving always is failure

[michaelmou]

let identifier = application.beginBackgroundTaskWithExpirationHandler {

        }

        MagicalRecord.saveWithBlock({ (context) -> Void in

            context.MR_saveWithOptions(MRSaveOptions.SynchronouslyExceptRootContext){ (succeed, error) -> Void in

                if error != nil{
                    print("error focus on saving persistenStore:\(error)")
                }
                application.endBackgroundTask(identifier)

            }

        })

@michaelmou Any Error is printing ?

[michaelmou]

anything is ok, but the parameter of succeed is false.

This is probably the result of a long running error in our logic. The BOOL was not supposed to be an indication of an error occurring — a save might not occur (and thus return NO) if there are no changes to save.

I know, it's a debatable choice. I should verify what Core Data does in this circumstance and copy that.

Yeah, so basically we're just passing back what NSManagedObjectContext gives us. If you try to save a context with no changes, the save result is NO. I don't think we should be going against what the framework does here, but I'm happy to consider arguments for it.
