私は、IOS と Monotouch にはかなり慣れていませんが、.NET と C# には精通しています。UIButton がイベントに応答していません。理由がわかりません。私は、MonoTouch を使用したプログラミングに関する教科書を少なくとも 3 冊読んだことがあります。また、stackoverflow と他のサイトの両方で多くの質問と回答を読みましたが、解決策が見つかりませんでした。ID を取得するために UIButton をサブクラス化しました。コードは次のとおりです。

using System;
using MonoTouch.UIKit;
using System.Drawing;

namespace Roombler.Views
{
    public class SmallDottedMonthButton : UIButton
    {       

        public SmallDottedMonthButton(int numberOfButton)
        {
            this.number = numberOfButton;
            UIImage image = UIImage.FromFile("Green.png");

            this.SetBackgroundImage(image, UIControlState.Normal);
        }

        public int number = 0;


    }
}

このコードはビュー内で使用されます。ボタンは正しく表示されますが、イベントを添付できません。userInteraction を有効にするとうまくいくと読んだことがありますが、私の場合はそうではありません。カスタム UIButton (smallDottedMonthButtonNr1 という名前のボタン) の使用方法は次のとおりです。

using System;

私はここで少し道に迷っており、本当に助けが欲しいのですが、どちらの方向に進むべきかのヒントが欲しいのです。

ボタンが追加される場所の境界/フレームを確認します。それはscrollViewですが、ボタンが表示されれば問題ないと思います。

ブレークポイントを設定します

    smallDottedMonthButtonNr1.SetTitle("Test", UIControlState.Normal);

まったく助けますか？

他のビューがボタンを覆っていないことを 100% 確信していますか?

また、好奇心から、TouchUpInside ではなく TouchDown を試してみてください。
