Convert a Static Library ".a" header file to Delphi


I have bough the RedPark serial cable to connect my iPad to one of our product.  I have very little knowledge of XCode and I am trying to interface the static library with Delphi Mobile and the Fire Monkey.  I spent 2 days trying to understand how the conversion works but it seems I am missing something.

Is there someone who can help me with an example on how to proceed. I believe I have the header file converted to delphi unit.  The 2 files compile without error.  I have a class for the delegate and I have the manager (see below). 

I have instantiate TRscMgr class but it seems that I cannot access any of the function in IRPRscMgr.  How do I access them?

And second, how do I create the Delegate, it does not have a create function?

    IRscMgrDelegate = interface(IObjectiveC)

        // Redpark Serial Cable has been connected and/or application moved to foreground.
        // protocol is the string which matched from the protocol list passed to initWithProtocol:
        procedure cableConnected(protocol : PNSString ); cdecl;

        // Redpark Serial Cable was disconnected and/or application moved to background
        procedure cableDisconnected; cdecl;

        // serial port status has changed
        // user can call getModemStatus or getPortStatus to get current state
        procedure portStatusChanged; cdecl;

        // bytes are available to be read (user should call read:, getDataFromBytesAvailable, or getStringFromBytesAvailable)
        procedure readBytesAvailable(length : UInt32); cdecl;

        // @optional
        // called when a response is received to a getPortConfig call
        procedure didReceivePortConfig; cdecl;

        // GPS Cable only - called with result when loop test completes.
        procedure didGpsLoopTest(pass : Boolean); cdecl;

    TRscMgrDelegate = class(TOCLocal, IRscMgrDelegate)

     IRPRscMgr = interface (NSObject)
        procedure setDelegate(delegate : IRscMgrDelegate);

        // Initializes the RscMgr and reigsters for accessory connect/disconnect notifications.
        procedure init;


    //here you define static class Methods
    IRPRscMgrClass = interface(NSObjectClass)

    //the TOCGenericImport maps objC Classes to Delphi Interfaces when you call Create of TObjc_TestClass
    TRscMgr = class(TOCGenericImport<IRPRscMgrClass, IRPRscMgr>)

Convert "BCC" to "To:"
I'm guessing the answer to this is no, but I thought I'd ask. Is there any way to set GWIA to convert a "BCC:" recipient to a "To:" recipient? (Each person would be it's own To: Address) The problem we are having is that we use BCC because we don't want people to see other customers email addresses. We have found that some Spam software is tagging the e-mail as spam because the customers name is not in the "To:" field. Your thoughts or comments would be appreciated. --Matt No there isn't. Nor should there be because the recipien...
