I would like to display a small `UIView` with some text in the center of a `UITableViewController` when I call the `showHud` method. 

```
- (void) showHud {

    UIView *paintView=[[UIView alloc]initWithFrame:CGRectMake(150, 150, 120, 30)];
    [paintView setBackgroundColor:[UIColor yellowColor]];
    [self.view addSubview:paintView];

}

```

Actually the problem with this code is that the view doesn't stays on its place, when I scroll the `tableview` it goes up with cells. Is it possible to pin it somehow?
