ios - 如何在 objective-c 中使用 uisegment Controller 更改 View Controller

Question

单击段时，我想更改 View Controller 。我有 UITabBarItem在底部，所以当我点击第二段或第一段时， View 应该在当前 View Controller 内发生变化。

当我使用该代码时，整个 View 与当前 View 重叠，这不是我想要的。

 if([sender selectedSegmentIndex] == 0) {
    //            UIStoryboard *mystoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    //            UITabBarController *wc = [mystoryboard instantiateViewControllerWithIdentifier:@""];
    //            [self.navigationController pushViewController:wc animated:YES];
NSLog(@"first");
       } else if([sender selectedSegmentIndex] == 1) {
    //        UIStoryboard *mystoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    //        UITabBarController *wc = [mystoryboard instantiateViewControllerWithIdentifier:@"ProfileViewController"];
    //        [self.navigationController pushViewController:wc animated:YES];

 NSLog(@"Second");
   UIStoryboard *mystoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
   ProfileViewController *wc = [mystoryboard instantiateViewControllerWithIdentifier:@"ProfileFirstViewController"];
   [self.navigationController pushViewController:wc animated:YES];

您需要自定义 View Controller 容器。
