iOS - 从代码和故事板推送viewController

Question

我有这个代码

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

我可以更改视图,但是当我在此页面返回时,我会推动此视图,状态仍然存在.

我试着把这段代码:

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

但什么也没做.

谢谢

Answer 1

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

检查2件事,

1. 你的故事板标识符是正确的.

2. 根视图有导航控制器.

Answer 2

对于情节提要，应该这样使用performSegueWithIdentifier：

 [self performSegueWithIdentifier:@"identifier goes here" sender:self];

Answer 3

使用：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"STORYBOARD_NAME" bundle:nil];
PlaceViewController *newView = [storyboard instantiateViewControllerWithIdentifier:@"PlaceView"];
[self presentViewController:newView animated:YES completion:nil];

要么：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"STORYBOARD_NAME" bundle:nil];
PlaceViewController *newView = [storyboard instantiateViewControllerWithIdentifier:@"PlaceView"];
[self.navigationController pushViewController:newView animated:YES];
