Question

I have a NSFetchResultsController that loads up my tableview.

When the app is first downloaded, there will be no data to show in the tableview so I want to have a static image with instructions on it. I have the following code and I call this method in viewWillAppear but it doesn’t function right. Any ideas?

- (void)checkIfEmpty
{
    if ([self.fetchedResultsController fetchedObjects] > 0)
    {
        self.defaultImage.hidden = NO;
        self.logTableView.hidden = YES;
    }
    else
    {
        self.defaultImage.hidden = YES;
        self.logTableView.hidden = NO;
    }
}

[self.fetchedResultsController fetchedObjects] > 0 will always be true because even an empty array is an object (and not nil).

You need to use self.fetchedResultsController.fetchedObjects.count > 0 instead.
