“loading” spinner not leaving the TTTableViewController

I had a TTTableViewController used in iPad and initially I want it to be empty. When it first loads it actually calls:

- (id)initWithNavigatorURL:(NSURL*)URL query:(NSDictionary*)query {
    if (self = [super init]) {
        self.dataSource = nil;
    }
    return self;
}

However, the "loading" spinner stays in there and won't go away. Why is this? I thought that this could happen because init wasn't called, but inde开发者_运维百科ed it is. I need some help.

When a TTTableViewController is presented on screen, it accesses it's model. If there's no model set, like in your case it creates a model in [TTModelViewController createInterstitialModel]. By default this will be a TTModel (the class not the protocol), which in turn does nothing then appearing to be loading.

In your createModel implementation you would need to create a model that does what you want and assign that to self.model.

Also note, that creating dataSources and / or model in the initializer is not optimal, consider creating your dataSources / models in createModel. They will be created only when needed (when the view appears on screen).
