iOS-按下“后退”按钮时，导航标题来自左侧

在我的应用程序中，当我访问某些视图控制器并触摸导航栏中的“后退”按钮时，生成的视图控制器的导航标题看起来来自左上角，看起来很难看

下面显示了这样一个实例的图片

我已按程序设置了标题

有人能告诉我为什么会发生这种情况，以及我如何解决它吗？提前谢谢

这是我的密码：

视图控制器B

    label.font = FONT_NAVIGATION_TITLE_BAR;
    label.text = [NSString stringWithFormat:PAGE_TITLE_ADD_SERVICE_PROVIDER];
    self.navigationItem.titleView = label;
    [label sizeToFit];


    UIButton *homeButton = [[UIButton alloc] initWithFrame:CGRectMake(20, 20, 20, 20)];
    [homeButton setImage:[UIImage imageNamed:IMG_HOME_MENU_BUTTON] forState:UIControlStateNormal];

也许你可以发布一些可能适用的代码？嗨@Mike，我添加了一些代码。请尝试不带动画的popViewControllerAnimated。[self.navigationController PopViewControllerInitiated:否]@V.J.试过了，没用/你能为[super createNavigationBar:USER_ACCOUNT_PAGE]输入代码吗；[超级设置导航标题：页面标题添加收款人]；[self.navigationController setNavigationBarHidden:无动画：动画]；
