回答1:

Set storyboard id of view controller in story board in identity inspector

Make a reference to your storyboard like

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];

then to your controller

YourController *vc = [storyboard instantiateViewControllerWithIdentifier:@"YourController"];// storyboardId

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

and you can also make segue and do

[self performSegueWithIdentifier:@"YourSegueIdentifier" sender:sender/nil];

回答2:

use this one :

- (IBAction)JoinClicked:(id)sender{

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

}

and add segue in storyborad like

Make an identifier for your push-segue in storyboard.

then use

[self performSegueWithIdentifier:@"YourSegueIdentifier" sender:nil];

When using story boards you should use segues for as much navigation as possible.

回答4:

Your code seems fine, please verify your outlets correctly configured or not in xib or storyboard.

Edit: You are using storyboard and wants the xib file to get pushed onto your view controller if I am not wrong, you can drag another view controller in storyboard and name it JoinWithViewController and push using segue on button click. That is much easier than what your trying to do here.
