私のMonotouchベースのiOSプロジェクトでは、2つのビューコントローラーがあります。最初のViewControllerで、xibによってボタンを作成しました。このボタンを選択すると、2番目のView Controllerを表示したいのですが、表示されておらず、アプリケーションがクラッシュします。

したがって、私のdesign.csファイルでは、これがボタンの作成方法です。

[Outlet]
MonoTouch.UIKit.UIButton firstButton { get; set; }

[Action ("clickMe:")]
partial void clickMe (MonoTouch.Foundation.NSObject sender);

これは、クラッシュの原因となっている.csファイルのボタンアクションメソッドにあります。

partial void clickMe (MonoTouch.Foundation.NSObject sender)

{

SecondViewController secondViewControllerObject=new SecondViewController();

this.PresentViewController(secondViewControllerObject, true, null);

}
