How to close this bottom bar in iOS9 simulator?

Question

When I use iOS9 simulator, a bottom bar will be shown over my app. When keyboard appears, it can do some undo / paste actions. In the first picture, I even cannot see my UITabBar now. What is this bar and how can I close it?

Answer 1

You've got two options:

1) Settings:

Settings -> General -> Keyboard ->Shortcuts -> Switch to off    

2) Code (iOS 9 +):

Objective-c:

textField.inputAssistantItem.leadingBarButtonGroups = @[];
textField.inputAssistantItem.trailingBarButtonGroups = @[];

Swift:

textField.inputAssistantItem.leadingBarButtonGroups = []
textField.inputAssistantItem.trailingBarButtonGroups = []
