如何在iOS中的uitabbarcontroller内部切换视图

Question

我正在使用UITabBarcontroller，我希望在UISegmentController之间切换视图，但点击UITabBarItem时不应隐藏UISegmentController：

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

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