Question

I’m trying to add a custom view to an UITableView created with code from an UITableViewController. This view is a HUD window with a message (MBProgressHUD)

So I have a method reload() called from the overridden initWithStyle() method and from the refresh button of the table:

- (void) reload {
    HUD = [[MBProgressHUD alloc] initWithView:self.tableView];
    [self.view addSubview:HUD];
    HUD.delegate = self;
    HUD.labelText = @"Downloading";
    [HUD showWhileExecuting:@selector(reloadWithHUD) onTarget:self withObject:nil animated:YES];
}

The first time, the HUD appears behind the table lines. Once loaded, when I press reload button, the view shows as expected. The initWithStyle() method (with some code removed for clarity) is:

- (id)initWithStyle:(UITableViewStyle)style {
    self = [super initWithStyle:style];
    if (self) {
        // Custom initialization.
        self.title = NSLocalizedString...

        UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithTitle ... action:@selector(reload)];
        self.navigationItem.rightBarButtonItem = button;
        [button autorelease];
        [self reload];      
    }

    return self;
}

I’ve tried changing the HUD view with a simple UILabel, with the same result.
I also changed the code to call reload() from viewDidLoad(), but doesn’t work either. How can I resolve this issue? Thank you very much.

EDIT : to clarify this, here is a possible solution to this problem. Many thanks to Bill Brasky for his help:

HUD = [[MBProgressHUD alloc] initWithView:self.view];
[[[UIApplication sharedApplication] keyWindow] addSubview:HUD];

Here is what I’m doing in my app with an almost identical application.

You need to add it to the main view WINDOW, not the tableView.

HUD = [[MBProgressHUD alloc] initWithView:self.view.window];
[self.view.window addSubView:HUD];
