Hi guys
This is one quite new and good introductory article about this subject.
http://dantes-andreea.blogspot.com/2012/01/how-to-use-objective-c-library-in.html
and with the est I usually go to Xamarin site:
http://docs.xamarin.com/ios/advanced_topics/binding_objective-c_types
P-Invoke my favourite (follow links to MSDN from it):
http://www.mono-project.com/Interop_with_Native_Libraries
For generating PInvoke wrappers for .net from dlls and *.h files see:
http://www.swig.org/tutorial.html
From MS interop team:
http://clrinterop.codeplex.com/releases/view/14120
I'm currently investigating this for some ideas...
regards
mel

I think that you need to build an XCode library (.a) project, and then
write MT bindings for it
I would really love to see a detailed step-by-step example of writing
bindings for an existing obj-c lib. Every time I've started down this
path I've given up because the process seemed overwhelming

OK. I am stumped on this one. I feel like I am way out of my depth
:-( I am
using MonoDevelop 2.8.6.3 and Monotouch 5.0.4.
I have been given a barcode scanner hardware accessory that the
iPhone plugs
into. It has an SDK for working with the device. The SDK is a
framework.
There is a 'driver' file and 49 .h files. There is no .a file. The SDK
instructions show how to add the framework to an xcode project and
use it.
Seems pretty straight forward. Except I am using MonoTouch :-)
I've read:
-
http://docs.xamarin.com/ios/advanced_topics/binding_objective-c_types
- http://docs.xamarin.com/ios/advanced_topics/linking_native_libraries
-
http://dantes-andreea.blogspot.com/2012/01/how-to-use-objective-c-library-in.html
but they aren't making a lot of sense to me.
The Binding Object C Types document seems to assume I already have
a .a
static library to use. So do I create a static library in xcode
and simply
add the framework to it and compile it? Will that be enough to give me
access to the definitions in the 49 .h files of the framework?
The document also talks about btouch. That seems to take a number
of .cs
files and generates a dll. The dll gets added to my real project. What
happens to the .a file? If I am reading correctly that gets
included with
the LinkWith option?
Where do the .cs files come from? There are 49 .h files? I don't
translate
each one of the individually do I? Do Xamarin provide tools to
automate the
generation of the files?
A guiding hand would be appreciated. I can sort of see what needs
to be done
but think I just need a slap round the head to point me in the right
direction!
Cheers
Jeff
