Using Apple’s XCode for open application development

When developing iOS application for jailbroken devices, you have to take care of many dirty details of application deployments on iOS.  In particular, you have to take care of creating and registering your own development certificate, as detailed below.

This is where IOSOpenDev comes into the game, this packages a set of XCode plugins that automates most of this process.  More than that : it also provides templates (aka empty project) to build your own Widgets, command line applications, SBSettings etc …

IOSOpenDev is a must use if you are serious about jailbroken app development on iOS.

But just for the sake of archiving – or if you want to do it manually, here is the process to code sign an application without using Apple’s provided certificate.

1/ generate self signed certificate using the Certificate Assistant in KeyChain Access application

2/ tell Xcode to use that identity


3/ change XCode signature method (and restart XCode)

marsu:Contents sst$ sudo cp Developer/Platforms/iPhoneOS.platform/Info.plist Developer/Platforms/iPhoneOS.platform/Info.plist.orig
marsu:Contents sst$ sudo /usr/bin/sed -i .bak 's/XCiPhoneOSCodeSignContext/XCCodeSignContext/' Developer/Platforms/iPhoneOS.platform/Info.plist
marsu:Contents sst$ ls Developer/Platforms/iPhoneOS.platform/Info.plist*
Developer/Platforms/iPhoneOS.platform/Info.plist      Developer/Platforms/iPhoneOS.platform/Info.plist.orig


4/ create, compile and deploy your application
scp -r root@ip_address:/Applications


5/ restart SpringBoard (Respring) or reboot


Enjoy !
