You can use MBProgress Hud class for loading view. You can download only two classes from here :-https://github.com/jdg/MBProgressHUD After you write this code in that class which you want to load the data Example :In your viewDidLoad you write this

- (void) viewDidLoad
{
    MBProgressHud *spinner =  [MBProgressHUD showHUDAddedTo:self.view animated:YES];

        spinner.mode = MBProgressHUDModeCustomView;

        [spinner setLabelText:@"Loading....."];

        [spinner setLabelFont:[UIFont systemFontOfSize:15]];

        [spinner show:YES];

        [self performSelectorInBackground:@selector(getData) withObject:nil];
}

- (void) getData
{
     NSURL *url = [NSURL URLWithString:@"http://i0.kym-cdn.com/entries/icons/original/000/005/545/OpoQQ.jpg?1302279173"]; 

        NSData *data = [NSData dataWithContentsOfURL:url]; 

        imageView.image = [[[UIImage imageWithData:data];

        [spinner hide:YES];

        [spinner removeFromSuperViewOnHide];
}
