How to make a fat library for MonoTouch in XCode


  1.  New Project in XCode ( i have version 4.3.3 )
  2. In Architectures from project options set the fallowing: $(ARCHS_STANDARD_32_BIT) armv6
  3. on the valid architectures set "armv6 armv7 i386" values
  4. on the Build Phases tab, add the Run Script code:
    # Version 2.0 (updated for Xcode 4, with some fixes)
    # Changes:
    #    - Works with xcode 4, even when running xcode 3 projects (Workarounds for apple bugs)
    #    - Faster / better: only runs lipo once, instead of once per recursion
    #    - Added some debugging statemetns that can be switched on/off by changing the DEBUG_THIS_SCRIPT variable to "true"
    #    - Fixed some typos
    #
    # Purpose:
    #   Create a static library for iPhone from within XCode
    #   Because Apple staff DELIBERATELY broke Xcode to make this impossible from the GUI (Xcode 3.2.3 specifically states this in the Release notes!)
    #   ...no, I don't understand why they did this!
    #
    # Author: Adam Martin - http://twitter.com/redglassesapps
    # Based on: original script from Eonil (main changes: Eonil's script WILL NOT WORK in Xcode GUI - it WILL CRASH YOUR COMPUTER)
    #
    # More info: see this Stack Overflow question: http://stackoverflow.com/questions/3520977/build-fat-static-library-device-simulator-using-xcode-and-sdk-4

How to use a objective-c library in monotouch

There are many nice objective-c libraries out there, and it you would loose precious time to port them in c#/monotouch.  But, with the new LinkWith attribute and the latest Monodevelop & Monotouch you can use a native library very easy.

I took for an example the iCarousel library from here wich is a great image gallery widget.


Ok, so these are the steps required:


- download the objective-c source code of iCarousel


- create a new project in Xcode ( i have Xcode 4.2 ), and call it for example "iCarousel". Choose the Cocoa Touch Static Library project type, like this:
replace the iCarousel.h and iCarousel.m files with the files from the downloaded source code.


Go to project settings.
In the "Build Settings" page, add the "i386" and "armv6" value to Architectures ( it must like like this:
"armv6 $(ARCHS_STANDARD_32_BIT)" )
Also change the "Valid Architectures" to i386 armv6 armv7.
Be sure to also change the "iOs deployment target" to the desired version.



Go to the "Build Phases" and add "-fno-objc-arc" as a value to all header files just under the "Compiler flags" ( apple select all them and press enter ).


Into the Link Binary With Libraries add:
  • CoreGraphics
  • UIKit
  • QuartzCore


You're almost done now.  You need to only add a small script to compile for simulator also.
Insert in RunScript the fallowing script like in this screenshot:




# Version 2.0 (updated for Xcode 4, with some fixes)
# Changes:
#    - Works with xcode 4, even when running xcode 3 projects (Workarounds for apple bugs)
#    - Faster / better: only runs lipo once, instead of once per recursion
#    - Added some debugging statemetns that can be switched on/off by changing the DEBUG_THIS_SCRIPT variable to "true"
#    - Fixed some typos
#
# Purpose:
#   Create a static library for iPhone from within XCode
#   Because Apple staff DELIBERATELY broke Xcode to make this impossible from the GUI (Xcode 3.2.3 specifically states this in the Release notes!)
#   ...no, I don't understand why they did this!

Okay.  Now you're ready to make the bindings :)  Just Clean & Build your project, and add the generated library file ( Attention! libiCarousel.a is in the in a folder Debug_universal or Release_universal) to your binding project in monotouch.  Be sure to make the LinkWith attribute look like this:

[assembly: LinkWith ("libiCarousel.a", LinkTarget.ArmV6 | LinkTarget.ArmV7 | LinkTarget.Simulator, ForceLoad = true, Frameworks="CoreGraphics QuartzCore UIKit")]

To make the bindings easier I'm using this little script based on the MonoMac parser class, that takes an objective-c header file and generate a c# binding interface for it.  It's not perfect, but it help's a lot.

After you make the binding interface, build your project, and the fresh new generated dll file in your projects :)

Happy coding!

Tapjoy publisher library for MonoTouch

Hello there monotouch users,

Tapjoy is a wonderful platform, but unfortunately they have not developed a library for monotouch users. And since C # is 10 times more beautiful and better for RAD than Objective-C, I decided to make it myself.

Basically I took the publishers library for XNA, and I adapted it for monotouch.

I hope this is helpful!

Download sources here.

Sample:
TapjoyConnect.Instance.TapjoyConnectCompleted += delegate(object sender, TapjoyConnectCompletedEventArgs e) 
{
 if( e.Succeeded )
  Console.WriteLine("tapjoy succeeded!");
 else
  Console.WriteLine("error; check your app id or secret key");
};
TapjoyConnect.Instance.RequestTapjoyConnect( APP_ID , SECRET_KEY );

How to compile Sparrow for Monotouch


Download the bindings from
https://github.com/trustme/Sparrow

and inside the folder with the bindings run these commands:


  • /Developer/MonoTouch/usr/bin/btouch sparrow.cs -s:enum.cs --outdir=gen -ns=Sparrow --unsafe --sourceonly=genfiles
  • /Developer/MonoTouch/usr/bin/smcs -out:sparrow.dll `cat genfiles` extensions.cs -unsafe -r:/Developer/MonoTouch/usr/lib/mono/2.1/monotouch.dll enum.cs -target:library
