iOS - 从代码和 Storyboard推送 viewController

Question

我有这个代码

 PlaceViewController *newView = [self.storyboard instantiateViewControllerWithIdentifier:@"PlaceView"];
 [self presentViewController:newView animated:YES completion:nil];

我可以更改 View ，但我会推送此 View ，因为当我返回此页面时，状态仍然存在。

我试着把这段代码:

[self.navigationController pushViewController:newView animated:YES];

但什么都不做。

谢谢

Answer 1

objective-C :

PlaceViewController *newView = [self.storyboard instantiateViewControllerWithIdentifier:@"storyBoardIdentifier"];
[self.navigationController pushViewController:newView animated:YES];

请注意以下几点，

1. 您的 Storyboard标识符是正确的。

2. Root View 有导航 Controller 。

swift :

let newView = self.storyboard?.instantiateViewController(withIdentifier: "storyBoardIdentifier") as! PlaceViewController
self.navigationController?.pushViewController(newView, animated: true)
