Answer 1

You need to use resignFirstResponder, see this similar question.

[myTextField resignFirstResponder];

Answer 2

See this answer for the easiest way to do it: Easy way to dismiss keyboard?

[self.view endEditing:YES];

Answer 3

Call -resignFirstResponder on your currently-editing text field.

Answer 4

There are cases where I don't have direct access to the 'first responder', so I tend to use a different approach. I have a utility class for the keyboard with, among other functions, this one:

+ (BOOL)dismiss:(UIView *)view
{
    if (view.isFirstResponder) {
        [view resignFirstResponder];
        return YES;
    }
    for (UIView *subView in view.subviews) {
        if ([Keyboard dismiss:subView]) // It's calling itself, just to be perfectly clear
            return YES;
    }
    return NO;
}

This lets me simply call for example: [Keyboard dismiss:self.view] from anywhere within a UIViewController.
