Trouble Refreshing JSQMessagesViewController

[baugarten]

I'm almost certain this is user error, as I'm new to iOS development, but any help would be greatly appreciated.

I'm trying to load messages from the server when loading my subclass of the JSQMessagesViewController. I'm following the demo. Essentially, now during setupTestModel, I make an asynchronous call to the server and once complete, try to render a static list of JSQMessage.

// setupTestModel
  [self asynchronouslyLoadData:^(NSArray *messages) {
    self.messages = messages
    [self.collectionView setNeedsDisplay];
    [self.view setNeedsDisplay];
  }];

And nothing happens. I haven't changed much in the ViewController from the Demo application, just changing the seed data to load asynchronously. Apologies if how I'm trying to reload the view is incorrect. I also tried doing

  [self viewDidLoad];
  [self viewWillAppear:YES];

But got issues with View constraints.

Have you confirmed you have data returned?

I made a gist of what I'm seeing

I only edited setupTestModel to set self.messages after the main view was rendered

I was just looking at how others use the framework and noticed this method https://github.com/relatedcode/AwesomeChat/blob/master/Chat/ChatView.m#L108, which does solve the problem.

Apologies for not R(ing)TFM
