Try to set the frame of the picker view to be equal to popover bounds. You should also remove the pickerview from its previous superview. — Valent Richie, Jun 12 '13 at 12:58
i understand how to set picker view same as popover but how to remove that from super view can you show something — java, Jun 12 '13 at 12:59
Try `[pickerView removeFromSuperview];` and you will need to make pickerView strong property so that it will not be released after it is removed from superview. — Valent Richie, Jun 12 '13 at 13:04
Try `pickerView.frame = popoverView.bounds;` for setting the frame. — Valent Richie, Jun 12 '13 at 13:05
ok i set it by contentSizeForViewInPopover but nothing happened — java, Jun 12 '13 at 13:06
popoverContent.contentSizeForViewInPopover = CGSizeMake(320, 216); which is size of my picker — java, Jun 12 '13 at 13:07
yes yes yes that happen but when i selection is done then only pickerview disappear pop over should disappear too — java, Jun 12 '13 at 13:10
you should keep a reference to the pop over view controller and call dismissPopoverAnimated to dismiss it — Valent Richie, Jun 12 '13 at 13:29

Seems your picker view is hidden somewhere in the pop over because the frame is not properly set yet. So try to set the frame of the picker view to be equal to the bounds of the pop over as a starting point:

pickerView.frame = popoverView.bounds;

But before adding the picker view as a subview in the pop over, you need to remove the picker view properly from the superview.

Now, by default Xcode will generate the IBOutlet as weak property, and this will cause the picker view to be deallocated when it is removed from the superview. So you will need to declare the picker view as a strong property first.

After that, you can remove it from the current superview:

[pickerView removeFromSuperview];

You should keep a reference to the pop over view controller, for example declaring it is a property, and call dismissPopoverAnimated to dismiss the pop over properly.
