Adding and removing keyboard

Question

I have a textfield and when the user clicks on it, they will be presented with the keyboard. there is a GO button on the keyboard, and i want to write an action event to it.

1.) How can i write an action when the user clicks on this button

2.) when the keyboard is open, and when the user clicks on the background i need the keyboard to disappear, how can i do this programatically?

I have no code to demonstrate, i have only added a texfield, so the keyboard would appear by default once clicked

for performing some action on return of textfield/ Go button use following code

-(BOOL)textFieldShouldReturn:(UITextField *)theTextField {
    [theTextField resignFirstResponder];

    //call Method when the GO button is pressed   

    return YES;
}

And when user touches on the background and keyboard should return - for that ,write below code

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {

[textFiedl resignFirstResponder];

}

hope your issues are resolved with this.

A textfield is present whenever a UITextField or UITextView is the first responder. You can manually "show" the keyboard by calling becomeFirstResponder or "hide" it by resignFirstResponder.

In your case, Look at the UITextFieldDelegate reference; when the user hits "GO", the textFieldDidEndEditing: callback is invoked. In this method, you should call resignFirstResponder on the text field to hide the keyboard.

For hiding the keyboard when you touch on the background you can write [txtName resignFirstResponder]; where txtName is the reference name of the TextField.
