Monotouch で Objective-c ライブラリをラップしています。問題は、btouch を使用して DLL を生成した後、DLL からいくつかのクラスをサンプル アプリケーションで使用しようとすると、ほとんどのクラスのclassHandleが0x0を返すことです。問題をデバッグしたところ、Messaging クラスで使用されるclass_ptrも 0x0 を返すことがわかりました。
(MonoDevelop でプロジェクトをビルドした後) ビルド出力を確認したところ、ネイティブ ライブラリがリンクされているように見えますが、それでも同じエラーが発生します。ビルド出力は以下に含まれています。問題は、プロトコル GDiOSDelegate が次のように定義されていることです
@protocol GDiOSDelegate
@required
- (void)handleEvent:(GDAppEvent*)anEvent;
@end
このプロトコルは GDiOS クラス (私も含めました) によって使用されますが、HandleEvent メソッドが UIApplicationDelegate からのいくつかのオブジェクトと通信する必要があるため、UIApplicationDelegate と対話する必要もあります (Objective-C でライブラリを使用する同等のサンプル コードにはクラスがありましたA : NSObject )。
私が持っていた方法は、GDiOSDelegate のバインディングで typeof プロパティを NSObject ではなく UIApplicationDelegate に設定することでした
[BaseType(typeof(UIApplicationDelegate))]
そのため、Monotouch バインディング DLL のいくつかのメソッドを使用した後に発生していたエラーに戻ると、AppDelegate が UIApplicationDelegate を実装していないという例外がスローされていました。
[Register ("AppDelegate")]
public partial class AppDelegate : GDiOSDelegate
{...}
これは、基本クラスとして GDiOSDelegate の代わりに UIApplicationDelegate を配置しても発生します。
