UIPopoverController wrong UITextField height in iOS 8

Question

In my app I use a UIPopoverController with an embedded UINaviagtionController to show a single line UITextField to enter a number. This kind of input was working up to iOS 7.1. Since iOS 8.0 the size of the UITextField is wrong. I tried out to change the AutoresizingMask, Frame, EdgesForExtendedLayout, ... but nothing is working.

As you can see in the screenshots bellow, there is a strange behaviour.

A sample project for Xamarin.iOS is available: http://www.danflash.com/files/dev/PopoverTest.zip

Answer 1

I have found the issue. I had to set contentViewController.EdgesForExtendedLayout = UIRectEdge.None; within the method:

public static PopoverInputController GetPopoverController(...)

It seems that Apple did some more changes to the UI regarding the layout stuff as expected.
