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

Answer 1

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.
