親子関係ではない、他のViewControllerのインスタンスの値を変更する
はじめまして。
全く関係のない(親子関係ではない)他のViewControllerの値を変更したいですが、うまく変更させることができません。
ご教授いただけますでしょうか。
【前提】
FirstViewController(FirstVC)にはscrollView上に乗っているteamIcon(UIButton)があり、自身のボタン画像としてrealm内に保存されたデータ(NSData)を取得している。
また自身をタップするとカメラロールを開き、画像を選択後、realmに保存することができる。
一方、SecondViewController(SecondVC)にも、teamIcon(UIImageView)があり、realm内に保存されているデータ(上記、FirstVCで述べているデータと同じもの)を表示している。
【やりたいこと】
FirstVCのteamIcon(UIButton)をタップ、realmに保存後、SecondVCのteamIcon(UIImageView)の画像も、そのタイミングで変更する。
【現状】
FirstVCのteamIcon(UIButton)をタップ後、AppDelegateを通じて、SecondVCのteamIconを変更するための関数の呼び出しは成功している模様(print()が動いていることから推測)。
だが、その関数内の teamIcon.image がうまく効いてくれない。
お手数をおかけしますが、アドバイス頂けると幸いです。
宜しくお願い致します。
