How to properly Pin in Parse localDataStore?

Question

I have Parse.enableLocalDatastore() in my app delegate before Parse.setApplicationId

Then I have var newPosts = PFObject(className: "Post") as a global variable.

Then I want to get 1,000 latest objects from the "Post" table from localDataStore that I enabled earlier so I do this:

var getNewPosts = PFQuery(className: "Post")
getNewPosts.fromLocalDatastore()
getNewPosts.limit = 1000
getNewPosts.orderByDescending("createdAt")
getNewPosts.findObjectsInBackgroundWithBlock {
    (downloadedPosts, error) -> Void in
        if downloadedPosts != nil && error == nil {
            println(downloadedPosts) // I am getting table with no data
        }
    }

But I only get empty data rows. If I comment out the getNewPosts.fromLocalDatastore() line results are fine.

I understand that I am missing the critical Pinning step but not sure from Parse documentation hoe and where to implement it. Can you please help?

Answer 1

You are getting no data.... reasons my be...

Wrong name of class (class names are case sensitive) Data is not there in local storage

Try synchronous version of findObject: method and pin: method.
