One way to do it, if you want to change all other buttons in the view is to iterate the subviews of the UIView that contains the UIButtons.

- (void)buttonTapped:(UIButton *)sender {
    for (id subview in self.view.subviews) {
        if ([subview isKindOfClass:[UIButton class]] && subview != sender) {
            UIButton *button = (UIButton *)sender;
            [button setTitle:@"new title" forState:UIControlStateNormal];
        }
    }
}
