Answer 2

The simplest solution is to set the following two properties:

• UIViewController : UIResponder inputAccessoryView
• UITableView : UIScrollView keyboardDismissMode

Boom, baby!

Answer 3

Luckily, Apple added the handy property keyboardDismissMode on UIScrollView to make your life a little easier.

Now your app can behave like Messages.app just by changing a single property on your Storyboard, or alternatively by adding one line of code!

This property uses the new UIScrollViewKeyboardDismissMode enum. The possible values of this enum are as follows:

UIScrollViewKeyboardDismissModeNone        // the keyboard is not dismissed    automatically when scrolling
UIScrollViewKeyboardDismissModeOnDrag      // dismisses the keyboard when a drag begins
UIScrollViewKeyboardDismissModeInteractive // the keyboard follows the dragging touch off screen, and may be pulled upward again to cancel the dismiss

Here’s the Storyboard property to change to dismiss the keyboard on scroll:

In swift you can use below code to get the view container of current keyboard (if exist), than you can change is's frame in your code:

UIApplication.shared.windows
    .filter{ NSStringFromClass($0.classForCoder) == "UIRemoteKeyboardWindow" }
    .first?.subviews.filter { NSStringFromClass($0.classForCoder) == "UIInputSetContainerView" }
    .first?.subviews.filter { NSStringFromClass($0.classForCoder) == "UIInputSetHostView" }
    .first

By the way here are a tool called Reveal make you can see the view hierarchical.

Answer 5

Short answer; They're most likely doing some 'Private API' thing there.

I'm most sure that the keyboard is in an independent view, above your app's window (You do not have access/control to it and it always displays on top, no matter what). The most you can do is have the input view become/resign first responder status, and the keyboard will appear/disappear accordingly: All or nothing.

You may be able to get a handle of the keyboard view and change its frame property (using undocumented properties of documented classes, and undocumented classes), but I'm pretty sure that will get you kicked out of the store.

Answer 6

I think the best way is to place a hidden button above the text input container. a long strip and when it detects a touchdown and release or cancel then hide the keyboard.

I'm going to try it and i will let you know how i go.
