UITabBarController裁剪

Question

button中有viewcontroller加载motherViewController。这似乎工作正常，但由于某种原因，新引入的view非常高，底部的内容被裁剪。

- (IBAction)LoginButton:(UIButton *)sender
{
        FirstViewController *FirstView = [self.storyboard instantiateViewControllerWithIdentifier:@"First"];
        SecondViewController *SecondView = [self.storyboard instantiateViewControllerWithIdentifier:@"Second"];
        ThirdViewController *ThirdView = [self.storyboard instantiateViewControllerWithIdentifier:@"Third"];
        FourthViewController *FourthView = [self.storyboard instantiateViewControllerWithIdentifier:@"Fourth"];
        FifthViewController *FifthView = [self.storyboard instantiateViewControllerWithIdentifier:@"Fifth"];

        FirstView.Username = self.UsernameBox.text;

        UINavigationController *FirstNavController = [[UINavigationController alloc]init];
        [FirstNavController pushViewController:FirstView animated:NO];

        UINavigationController *SecondNavController = [[UINavigationController alloc]init];
        [SecondNavController pushViewController:SecondView animated:NO];

        UINavigationController *ThirdNavController = [[UINavigationController alloc]init];
        [ThirdNavController pushViewController:ThirdView animated:NO];

        UINavigationController *FourthNavController = [[UINavigationController alloc]init];
        [FourthNavController pushViewController:FourthView animated:NO];

        UINavigationController *FifthNavController = [[UINavigationController alloc]init];
        [FifthNavController pushViewController:FifthView animated:NO];


        tabBar = [[UITabBarController alloc]init];    
        tabBar.viewControllers = [NSArray arrayWithObjects:FirstView, SecondView, ThirdView, FourthView, FifthView, nil];
        [self.view addSubview:tabBar.view];

}

Answer 1

我不知道我是不对。但是答案是，您尝试将UIViewController (UITabbarController)添加到ViewController。因此，您需要将其放在view中，例如

tabbar.view.frame = CGRectMake(0, 0, 320, 460);

但是，当我们添加到window时，我唯一不知道它是如何完美定位的。通过为frame设置tabbarcontroller来尝试使用您的代码。

试试这个 -

 tabBar.tabBar.autoresizingMask = UIViewAutoresizingFlexibleBottomMargin;
