+ (void)addCustomBackButtonForController:(id )iViewController withNavBar:(UINavigationController *)iNavController andNavItem:(UINavigationItem *)iNavItem {
    if ([self isIOS7orAbove]) {
        UIImage *backArrow = [UIImage imageNamed:kMyIOS7BackButtonImage];
        UIButton *aBackButton = [UIButton buttonWithType:UIButtonTypeSystem];
        CGSize aBackButtonTextSize = [MyLocalizedBackButton sizeWithFont:[UIFont systemFontOfSize:17.0]];
        aBackButton.frame = CGRectMake(0.0, 0.0, aBackButtonTextSize.width + backArrow.size.width, iNavController.navigationBar.frame.size.height);
        aBackButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
        SEL backSelector = NSSelectorFromString(@"backAction");
        [aBackButton addTarget:iViewController action:backSelector forControlEvents:UIControlEventTouchUpInside];
        [aBackButton setTitle:MyLocalizedBackButton forState:UIControlStateNormal];
        [aBackButton setImage:backArrow forState:UIControlStateNormal];
        [aBackButton setExclusiveTouch:YES];

        if ([self isIOS7orAbove]) {
            aBackButton.titleLabel.font = [UIFont systemFontOfSize:17.0];
        } else {
            aBackButton.titleLabel.font = [UIFont boldSystemFontOfSize:12.0];
        }

        UIBarButtonItem *aLeftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aBackButton];
        UIBarButtonItem *aNegativeSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
        aNegativeSpacer.width = kMyIOS7BarButtonNegativeSpacerWidth;
        iNavItem.leftBarButtonItems = @[aNegativeSpacer, aLeftBarButtonItem];
    } else {
        UIButton *aCustomBackButton = [UIButton buttonWithType:101];
        SEL backSelector = NSSelectorFromString(@"backAction");
        [aCustomBackButton addTarget:iViewController action:backSelector forControlEvents:UIControlEventTouchUpInside];
        [aCustomBackButton setTitle:MyLocalizedBackButton forState:UIControlStateNormal];
        [aCustomBackButton setExclusiveTouch:YES];

        if ([self isIOS7orAbove]) {
            aCustomBackButton.titleLabel.font = [UIFont systemFontOfSize:kFontSize17];
        } else {
            aCustomBackButton.titleLabel.font = [UIFont boldSystemFontOfSize:kFontSize12];
        }

        UIBarButtonItem *aLeftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aCustomBackButton];
        iNavItem.leftBarButtonItem = aLeftBarButtonItem;
    }
