頭の中の消しゴムの威力が強すぎる... MainStoryboardのViewControllerにidentifierをつけよう まず、値を渡したい側のViewControllerに、以下のようなidentifierをつける。 以下のようなコードを書く - (IBAction)nextButton{ SecondViewController *secondVC = [self.storyboard instantiateViewControllerWithIdentifier:@"SecondViewController"]; secondVC.secondNum = self.firstNum; [self presentViewController:secondVC animated:YES completion:nil];//YESならModal,Noなら何もなし }
