Can an iOS Xcode app install MonoTouch?

I am considering how best to split the effort between teams on a new project. We have a Windows C # application services team and a small iOS Objective-C team. Most likely, sooner or later you will need an Android application.

The domain level / api component on the device, which calls our services and processes synchronization with the local data store, is a logical component for writing in C # and compiling using MonoTouch. The Objective-C command then refers to this component. Is it possible? I read a lot about MonoTouch, referring to C assemblies, but can it work the other way around?

It would be great to hear of any experiences trying to apply this approach, if possible!

Thanks Aaron

Although technically possible, there is no easy way to do this today.

The best thing you can do now is run the application with C # and then, if you want, transfer control to your Objective-C code. During C # startup, you can register methods that will be called back with Objective-C code using P / Invoke to call something like:

delegate void some_callback_t (int parameter1, int parameter2);

[DllImport ("__Internal")]
void SetCallback (some_callback_t callback);

static void mycallback (int parameter1, int parameter2)
{
    // Here goes your C# logic to be called by C
}

Then you call:

SetCallback (mycallback);

Note that mycallback must be static (a limitation of static compilation). Then your Objective-C code can consume services, implementing something like:

 typedef (*callback_t) (int p1, int p2);
 callback_t callback;
 void SetCallback (callback_t cb)
 {
     callback = cb;
 }

 void InvokeCSharp ()
 {
     callback (1, 2);
 }
