在我基於Monotouch的iOS項目中，我有2個視圖控制器。在第一個ViewController中，我通過xib創建了一個按鈕。 現在選擇這個按鈕，我想顯示第二個視圖控制器，但它沒有發生，並導致應用程序崩潰。在Monotouch中以模態方式顯示視圖控制器
所以在我design.cs文件，這是創建按鈕
[Outlet]
MonoTouch.UIKit.UIButton firstButton { get; set; }
[Action ("clickMe:")]
partial void clickMe (MonoTouch.Foundation.NSObject sender);
這是在cs文件我的按鈕操作方法，這是造成飛機墜毀的方式。
partial void clickMe (MonoTouch.Foundation.NSObject sender)
{
SecondViewController secondViewControllerObject=new SecondViewController();
this.PresentViewController(secondViewControllerObject, true, null);
}
錯誤說明： -
得到了SIGABRT在執行本機代碼。
終止運行時，由於未處理的異常

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

你可以分享第二個控制器的代碼，我想知道是否有需要看的東西。 – 2013-02-10 21:13:14
