tableView and how to correctly use "Load more..." - ios

Question

I'm have kind of a really small and annoying problem. (No pun intended)
I kind seem to find my mistake. I also asked in chat, but we couldn't find the solution. I got the "Load more..." for my tableView from Abizerns github and implemented it. It works, except for the part, that when it starts up I have to click "Load more...". So on start it doesn't show me the first entries of the tableView until I clicked on "Load more...". You can see my annoyance. Maybe someone can spot my mistake, so that the tableView actually loads the first ten entries on start up.

#define PADDING 10.0f

self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
numberOfItemsToDisplay = kNumberOfItemsToAdd;
return self;
}

Answer 1

I haven't used a "Load more..." implementation, but maybe what you need is add [self.tabelle reloadData] in your - (void)viewWillAppear:(BOOL)animated method.

Answer 2

What method gets called when you click "Load more..."? Can you not programmatically call that method when the tableview is loaded?
