Set UIPopOverController size

Question

I have a view with a bunch of button in a UIScrollView. When the user presses a button, I want a UIPopOverController to display pointing at the selected button. It kind of works, but the popover is the wrong size and points to a random point in the view. Here is my code.

-(void)detail:(id)sender{
    UIButton *button = sender;
    NSLog(@"tag = %i", button.tag);

    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    self.popover = [[UIPopoverController alloc] initWithContentViewController:navController];
    self.popover.delegate = self;
    [self.popover presentPopoverFromRect:button.bounds inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}

Than the problem with the size of the popover: In the view that is inside the popover, I have:

self.contentSizeForViewInPopover = scroll.contentSize;
NSLog(@"%f, %f", scroll.contentSize.height, scroll.contentSize.width);
NSLog(@"showing: %f, %f",  self.contentSizeForViewInPopover.height,  self.contentSizeForViewInPopover.width);

and both logs are matching. So I think everything should work correctly. But it doesn't. Here is a screen shot. Let me know if you need more of my code. Thanks in advance.

Regarding the size of the popover only: I managed to do it with a variable heighted UILabel:

UILabel *hinweis;
hinweis.text = @"...";
hinweis.frame = CGRectMake(x,y,width,800);
[hinweis sizeToFit];

And for the arrow: have you tried a different inView param like self.parentViewController.view?
