问题描述
我有这个代码
PlaceViewController *newView = [self.storyboard instantiateViewControllerWithIdentifier:@"PlaceView"];
[self presentViewController:newView animated:YES completion:nil];
并且我可以更改视图，但是当我返回此页面时，我会推送此视图，状态仍然存在.
And I can change view, but I would push this view for when I return at this page, the state persists.
我试着把这个代码:
[self.navigationController pushViewController:newView animated:YES];
但什么都不做.
谢谢
推荐答案
Objective-C:
PlaceViewController *newView = [self.storyboard instantiateViewControllerWithIdentifier:@"storyBoardIdentifier"];
[self.navigationController pushViewController:newView animated:YES];
请注意以下几点，
您的故事板标识符正确.
your storyboard identifier is correct.
根视图有导航控制器.
斯威夫特:
let newView = self.storyboard?.instantiateViewController(withIdentifier: "storyBoardIdentifier") as! PlaceViewController
self.navigationController?.pushViewController(newView, animated: true)
