Demo is broken in iOS 8.

[klauslanza]

Demo is broken in iOS 8 ipad device, the view don't scroll back after the keyboard dismissal. I have problem also using in a project of mine, I'm trying to figure out where is the problem. Any idea already tried?

I haven't run the demo for a long time... I look into it next week

Is you view using Springs and Struts or Autolayout? And if Autolayout, are you applying them programatically or in IB?

There are a few issues with keyboard undocking in iOS 8 (most notably the UIKeyboardWillHideNotification is not sent correctly when the keyboard is undocked). See http://openradar.appspot.com/18010127 for more information.

I'm using spring and struts.

Regarding the demo: Using the iPad simulator 7.1 works both in landscape and portrait, 8 in landscape is quite working (sometimes the frames are off) but in portraits the view remains scrolled even after the keyboard is dismissed or just blows all the way up. Check this Vine I did https://vine.co/u/907571708674846720

Klauslanza, can you check that your target view is near the bottom of the screen. The target view needs to be obscured by keyboard to trigger the avoiding.

I hadn't done any iOS8 iPad testing - sounds like there's a bug - I'll look into it next week. Thanks guys for raising the issue.

iOS 8 keyboard is seriously flawed. I could dig a little bit deeper to better understand those issues, here is what I found.

If you split, merge, dock or undock the keyboard by long-pressing the ⌨ key and choosing the corresponding option, the keyboard seems behaves correctly as on iOS 7, besides a few graphical glitches. It is when you start moving the keyboard around with the ⌨ key pressed that many issues arise:

• On iOS 7, moving the docked keyboard upwards meant undocking and splitting it. On iOS 8, this might happen or not:
  • Sometimes it will stay grouped when moved upwards, provided the interface is in portrait orientation. But if you then long-press the ⌨ key, you will see that the keyboard still believes to be docked, since you are presented with the Undock option. The UIKeyboardWillHideNotification and UIKeyboardDidHideNotification notifications are not received when undocking the keyboard this way
  • Sometimes it will split when moved upwards. If you then long-press the ⌨ key on this split keyboard, you are presented with the correct Merge and Dock and Merge options. Though the keyboard seems to work correctly in this case, the UIKeyboardWillHideNotification and UIKeyboardDidHideNotification notifications are not received in this case either
• On iOS 7, moving the undocked / split keyboard downwards meant docking it. On iOS 8, this still seems to happen, but again the behavior is buggy:
  • If the keyboard is grouped when moved downwards, it will dock at the bottom. If you then long-press the ⌨ key, you are namely correctly presented with the option to Undock it. Sadly, though, the UIKeyboardWillShowNotification and UIKeyboardDidShowNotification notifications are not received
  • If the keyboard is split before it is moved downwards, it will merge and dock at the bottom. In this case, you also correctly receive the UIKeyboardWillShowNotification and UIKeyboardDidShowNotification notifications

I gave the class-dumped headers a deeper look, even tried some swizzling and private API calls for fun, but I could not solve all those issues at the same time. The iOS 8 keyboard implementation is far more complex than iOS 7 one, and currently seems like a buggy mess.

I suggest you should not lose too much time trying to fix the issues above. All official information you know about the keyboard stems from notifications, and you cannot do much to fix related issues without using private APIs. Instead:

• Run your application on iOS 7 and ensure that your component behaves well. iOS 7 behavior is correct, issues you might encounter will be yours
• When correct, test your scroll view on iOS 8, but only by long-pressing the ⌨ key to split, merge, dock or undock the keyboard
• Wait until Apple teams fix keyboard bugs in a later release
