Arrow on popViewController not going where I tell it

Question

I have a UIPickerController that appears when you click a button though the arrow on it doesn't change position from the bottom even when I use UIPopoverArrowDirectionUp.

- (IBAction)addPicture:(id)sender {
    CGRect rect = CGRectMake(0,650,768,1024);
    [popOverController presentPopoverFromRect:rect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}

I guess this must be quite common

Thanks in advance

My guess is it has something to do with the frame you are defining — Jason Renaldo, Aug 20 '13 at 19:48
Try calling [yourPopover setPopoverArrowDirection: UIPopoverArrowDirectionDown] after just to rule that out — Jason Renaldo, Aug 20 '13 at 20:03
Tried it though found that if I change some dimensions that I can get it on top though I don't know the dimensions of a popover so can't center it — Hive7, Aug 20 '13 at 20:08
There are no dimensions of a UIPopover...you are defining it by the elements you are placing within it. — Jason Renaldo, Aug 20 '13 at 20:13

You are sending a rect that has as width 768 and height 1024 starting on 0 and 650, so its a huge element that is causing this unexpected behaviour. You should send as rect the rect of the button the user is pressing. Try this way instead.

- (IBAction)addPicture:(id)sender {
    [popOverController presentPopoverFromRect:[sender frame] inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
