MainViewController.m＆hとFlipsideViewController.m＆hを備えたシンプルなユーティリティアプリがあります。ストーリーボード内に、MainViewControllerにボタンがあります。ボタンをクリックしてFlipsideViewController.mでメソッドを実行できるようにしたいのですが、これは可能ですか？これは私の最初のアプリであり、私は完全な初心者です。すべてのコメント/提案を歓迎します。
enter code here
これはFlipsideViewController.mにあります。これは、ボタンをクリックしたときに呼び出したいものです。
- (void)SaveFPQData
{
NSLog(@"Data Saved");
}
これは私がMainViewController.mに持っているものです
- (IBAction)saveButton:(id)sender
{
}
これは私がこれまでに持っているコードです。
