Closing the Keyboard
how do you get the keyboard to go away?
Go ahead and try.
Closing the keyboard when done is Tapped
the keyboard is software-based, we need to take a few extra steps to make sure the keyboard
goes away when the user is finsihed with it .
when the user taps the Done button on the text keyboard.
a Did End On Exit event will be generated, and at that time , we need to tell the text field to tive up control so that the key board
will go away.
add an action method to our controller class.
Control_FunViewController.h
switch over to .m, we'll implement this method.
add the following method to .m
the first responder is the control with which the user is
currently interacting. In our new method ,we tell our control to resign
as a first responder, giving up that role to the previous control the user worked with.
When a text field yields first responder status , the
keyboard associated with it goes away.
Double-click .xid to hop back ouer to IB and trigger this action from both of our tet field
single click the Name text field , press 2 to bring the connecton in
inspector we want Did End On Exit since that is the event that will file when the uer taps the Done button on th ekeyboad
