Answer 1

May be I don't understands what you want properly but - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch method may help you for dismissing the keyboard

Answer 2

To resign the current first responder, I tried using endEditing, but had some issues setting a first responder afterwards. I then used a recursive method for awhile to find the first responder in a UIView category method:

- (UIView *)getFirstResponder {

    if (self.isFirstResponder) {
        return self;
    }

    for (UIView *subView in self.subviews) {
        UIView *firstResponder = [subView getFirstResponder];

        if (firstResponder != nil) {
            return firstResponder;
        }
    }

    return nil;
}

Once the responder is returned, then I can just call resignFirstResponder on it.

Just today though, a buddy of mine at work showed me an even better way here: http://overooped.com/post/28510603744/i-had-completely-forgotten-about-nil-targeted

Just call this:

[[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];

Awesome one liner!
