Display a view when keyboard is visible

Generally when the key board is visible some apps display a开发者_JS百科 view on the top of keyboard with buttons like Done, Auto fill, .. etc

My Question is :

Is this provided by Apple or We have to create and use it.

Thank You in advance

The answer is somewhere in the middle. You do have to create it yourself, but Apple provides support for it. See Programmatically align a toolbar on top of the iPhone keyboard
