Question

I have a UITableViewController, when there is no data to populate the UITableView, I want to add a button, which uses an image. So, rather than the user seeing a tableview with no records, they will see an image that says, “No records have been added, Tap to add one”, then they click and we create a new one.

I assumed I would just hide the UITableView, then create the button, but I never see the button. Here I am using:

if ([[fetchedResultsController sections] count] == 0) {
        self.tableView.hidden = YES;
        // Create button w/ image
        UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        btn.frame = CGRectMake(0, 0, 100, 50);
        [btn setImage:[UIImage imageNamed:@"no-rides.png"] forState:UIControlStateNormal];
        [self.view addSubview:btn];
    }

Ideas on why I would never see the button? When I show this view, it seems to have a transparent background for a second, then changes white…

I am not sure if it works but you can try this:

1. If your view controller is not a UITableViewController and it contains a UITableView
   [self.tableView removeFromSuperview]; then [self.view addSubview];

2. If your view controller is a UITableViewController, you may need to consider to set the first row to contain the image and text. Then, you can handle the event: tableView:didSelectRowAtIndexPath: and if user click on the first cell, you trigger the method handle the button event
