How dismiss a viewController with storyboard from a push segue?

Question

I don't know why dismissViewControllerAnimated:completion: . I just want to do it.

I start with a

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

But is I call the dismiss than nothing happens. I can create another segue, but it create a new view controller.

My question is: How dismiss the performSegueWithIdentifier:sender: ?

Answer 1

Do you have a navigationBar in the viewController that's calling:

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

If so, you'll need to use:

[self.navigationController popViewControllerAnimated:YES];

to pop the view off the stack. There's one segue call, but the framework seems to call:

presentViewController:animated:completion:

or:

pushViewController:animated:

as appropriate.

Answer 2

You could just call

[self dismissViewControllerAnimated:YES completion:nil];

from the view controller since the view controller was pushed by segue.

Answer 3

[my_segue_view_controller dismissModalViewControllerAnimated: YES] ?

(not sure, but it works in my practice)

Answer 4

performSegueWithIdentifier:sender: itself isn't dismissed, that's just the method that's called to initiate a named segue. What happens in the segue is of more interest.

You're right that you should call dismissViewControllerAnimated:completion: , and it should be called by the presenting view controller, which has previously called the presented view controller using presentViewController:animated:completion: . For more info, see the UIViewcontroller docs .

Answer 5

使用以下代码为Swift 4版本

  self.navigationController?.popViewController(animated: true)
