以编程方式呈现新视图后，TabBarController消失

Question

在大量寻找解决方案并没有找到正确答案后，我发布了问题：执行时，我有两个viewControllers company和companyDetail

CompanyViewDetail *cDetail = [[CompanyViewDetail alloc] init]; [self presentViewController:cDetail animated:YES completion:nil];

它导航到companyDetailViewController，但是我在AppDelegate中创建的tabBar消失了，下面是代码：

tabBars = [[UITabBarController alloc] init]; self.window.rootViewController = tabBars; self.tabBars.view.autoresizingMask = (UIViewAutoresizingFlexibleHeight); [self.window makeKeyAndVisible];
