を使用してBと言うビューを提示しています
[self presentViewController:vc animated:YES completion:nil];
そして、このビューから私はそれを閉じてビューAに戻ります
[self dismissModalViewControllerAnimated:YES];
今戻ったら、前のビューのリロードを呼び出したいです(ここではビューA)。ビューAは、サーバーからのデータのリストを持つテーブルビューです。したがって、新しいデータはサーバーからのみ取得できるため、reloadtable は機能しません。要するに、ビューBを閉じながら、そのサーバーを呼び出してそのビューを更新したい.
これを行う方法。?
ビュー A の ViewWillAppear メソッドで ViewDidLoad を呼び出してみましたが、うまくいきませんでした。
これを手伝ってください。
EDIT:私のサーバーコールはこのようなものです
