以编程方式从viewcontroller到tabbar的视图

Question

嗨，这是我的故事板，我想从First view controller转到LoggedinViewController。

我通常使用

[self performSegueWithIdentifier:@"s1" sender:self];

但如果我添加标签栏控制器这行不起作用，我该如何解决这个问题呢？

Answer 1

如果已嵌入导航控制器，则可以使用以下内容。

UIStoryboard *myStoryBoard =[UIStoryboard storyboardWithName:@"Story_Board_Name" bundle:nil];
 UITabBarController *tabBarController = [myStoryBoard instantiateViewControllerWithIdentifier:@"TABid"];
self.tabBarController.selectedIndex = 0;
 [self.navigationController pushViewController:self.tabBarController animated:YES];

或试试这个

UIStoryboard *myStoryBoard =[UIStoryboard storyboardWithName:@"Story_Board_Name" bundle:nil];
 UITabBarController *tabBarController = [myStoryBoard instantiateViewControllerWithIdentifier:@"TABid"];
self.tabBarController.selectedIndex = 0;
[self performSegueWithIdentifier:@"s1" sender:self];

Answer 2

为你的tabbarcontroller提供一个来自故事板的标识符，就像这样做

 UIStoryboard *myStoryBoard =[UIStoryboard storyboardWithName:@"Your_Story_Board_Name" bundle:nil];
 TabViewController *tabBarController = [myStoryBoard instantiateViewControllerWithIdentifier:@"TAB_Identifier"];
 [self presentViewController:tabBarController animated:YES completion:nil];  

希望这有帮助

首先将“ tabbarid”赋予情节提要中的该标签

onClickHandlerForAdd = price => () => {
    this.setState({ sum: price });
}
