I am trying to create a binding for Good Dynamics so it can be used in Xamarin. I have finally got it to a point where it will build however when trying to initialize Good Dynamics the following error happens;
MonoTouch.Foundation.MonoTouchException: Objective-C exception thrown. Name: NSInternalInconsisenter code heretencyException Reason: AppDelegate does not implement UIApplicationDelegate. Check that the class is correct and it conforms to this protocol.
at (wrapper managed-to-native) MonoTouch.ObjCRuntime.Messaging:void_objc_msgSend_IntPtr (intptr,intptr,intptr)
at GDBinding.GDiOS.InitializeWithClassConformingToUIApplicationDelegate (MonoTouch.ObjCRuntime.Class applicationDelegate) [0x00000] in <filename unknown>:0
at GDTest.Application.Main (System.String[] args) [0x00006] in /Users/gareth/GDTest/GDTest/Main.cs:20
Line 20 of Main.cs is
GDiOS.InitializeWithClassConformingToUIApplicationDelegate(new MonoTouch.ObjCRuntime.Class(typeof(AppDelegate)));
I tried having AppDelegate extend UIApplicationDelegate and also extend GDiOSDelegate which has a base type of UIApplicationDelegate with the same results.
namespace GDBinding
{
[BaseType (typeof (NSObject), Delegates = new string[] {"WeakDelegate"}, Events = new Type[] {typeof(GDiOSDelegate)})]
interface GDiOS {
[Export ("delegate", ArgumentSemantic.Assign)]
NSObject WeakDelegate { get; set; }
[Wrap("WeakDelegate")]
[NullAllowed]
GDiOSDelegate Delegate { get; set; }
//+ (void)initializeWithClassNameConformingToUIApplicationDelegate:(NSString*)applicationDelegate;
[Static, Export ("initializeWithClassNameConformingToUIApplicationDelegate:")]
void InitializeWithClassNameConformingToUIApplicationDelegate (string applicationDelegate);
//+ (void)initialiseWithClassConformingToUIApplicationDelegate:(Class)applicationDelegate;
[Static, Export ("initializeWithClassConformingToUIApplicationDelegate:")]
void InitializeWithClassConformingToUIApplicationDelegate (Class applicationDelegate);
//+ (BOOL)isInitialized;
[Static, Export ("isInitialized")]
bool IsInitialized();
//+ (GDiOS*)sharedInstance;
[Static, Export ("sharedInstance")]
GDiOS SharedInstance();
//- (UIWindow*)getWindow;
[Export ("getWindow")]
UIWindow GetWindow();
}
[BaseType(typeof(UIApplicationDelegate))]
interface GDiOSDelegate {
[Abstract, Export("handleEvent:")]
void HandleEvent(GDAppEvent anEvent);
}
[BaseType(typeof(NSObject))]
interface GDAppEvent {
[Export("message")]
string Message { get; set; }
[Export("code")]
GDAppResultCode Code { get; set; }
[Export("type")]
GDAppEventType EventType { get; set; }
}
}
The code is at https://github.com/garethrhughes/GDTest
I think the problem may be something to do with passing the monotouch AppDelegate into the native library.
Any ideas?
Thanks
I know this is an old thread, but a colleague and I just went through this process with the newer version of GOOD's SDK (v1.8.x) and were able to get it working. We posted a writeup about it here which contains a link to a sample project as well.
