MBProgressHUD call from ViewDidLoad

Question

I call my rss parser from MBProgressHUD and at the moment it's in viewdidappear and it works, however I want it in viewdidload so when I go back it doesn't reload it - however when I move it in to viewdidload it runs the process but not the MBProgressHUD.

- (void)viewDidLoad {
    [super viewDidLoad];

        self.title = @"Results";

    HUD = [[MBProgressHUD alloc] initWithWindow:[UIApplication sharedApplication].keyWindow];


    [self.view.window addSubview:HUD];
    HUD.delegate = self;

    HUD.labelText = @"Loading";
    HUD.detailsLabelText = @"updating data";

    //Show the HUD while the provided method executes in a new thread
    [HUD showWhileExecuting:@selector(loadResults) onTarget:self withObject:nil animated:YES];


    }

Any ideas?

Thanks, Tom

In viewDidLoad method, the self.view will be loaded without its superview and window. For Example, self.view.superview will be loaded in viewWillAppear method, then self.view.window will be loaded in viewDidAppear method. That's why the [self.view.window addSubview:HUD] won't be happened in viewDidLoad, but the [self.view addSubview:HUD] works.

Try below code, its working fine at my end.

- (void)viewDidLoad {
    [super viewDidLoad];    
    HUD = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    HUD.labelText = @"Loading";
    HUD.detailsLabelText = @"updating data";    
}

Where on that do you tell it what to load? For example i use the ShowWhileExecuting bit to say my subroutine of loadResults to run – MissCoder87 Oct 04 '11 at 12:00
I've added what you've added then my showWhileExecuting and it's working now. Thankyou – MissCoder87 Oct 04 '11 at 12:10
