I've successfully downloaded and built the iOS project and the app runs great from xcode. The app will not run when launched from the device however. I've not got a jailbroken device but I've been using my apple developer signing identity. I commented out this code and added my signing identity to the target.

#export CODESIGN_ALLOCATE=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate
#if [ "${PLATFORM_NAME}" == "iphoneos" ]; then
#/Developer/iphoneentitlements401/gen_entitlements.py "org.xbmc.xbmc_ios" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent";
#codesign -f -s "iPhone Developer" --entitlements "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/"
#fi

Anyone have any ideas about what I need to change in the project to get this working correctly? Am really excited to show people but can only run it attached to my computer!

When the app doesn't start it doesn't seem to be getting anywhere in the app, it almost looks like the OS is stopping it before it can start but i've got the provisioning profile setup ok as i can debug it from xcode.

I have the exact same problem. I also built it with my apple developer signing identity.

What I modified is the code signing script like you, and CFBundleIdentifier from org.xbmc.xbmc_ios to org.xbmc.xbmc-ios in xbmc/osx/ios/XBMCIOS-Info.plist.

It works well when launched from debugger, but crashes right after launched on device.

crashlogs would be nice to see.

There are no crash logs. It doesn't appear to even make it to the first line of the main method. It stops running very fast like there are missing requirements or something.

iOS 4.2.1 or 4.3 ?

Both. No change since I upgraded.

I suspect that the problem is due to XBMC's internal use of dynamic libraries:

I also tried to run XBMC on a non-jailbroken iPad by signing it with an Apple developer certificate. It works when started from Xcode. But when I try to run the app by tapping its icon, it does not seem to make it to main. This is the corresponding crash log: http://pastebin.com/AyPLauGU. Unfortunately, I didn't save the console log.

If I replace all dynamic libs with their static counterparts in the project below XBMC-IOS/External Libs, I still get a crash:

But on the console, it seems that XBMC starts and is killed because of trying to fork():

Has anyone figured this out yet? I'm having this exact same issue.

when you run under xcode, you are in xcode's sandbox. when run as an app. then you are in a real sandbox. You need to setup a xbmc with proper sandbox profile and allow those things it needs.

Interesting how you appear to have the same basic issue that I have with building and running from Xcode:

http://forum.xbmc.org/showthread.php?tid=99812

but my crashes are SIGKILLs (signal 9) and yours are bus errors (signal 10).

So I'm wondering if any progress has been made on this since I saw in a thread somewhere that davilla got hardware acceleration working on 4.3

Here's my console log - hoping someone could make heads or tails of it and hopefully see something here that can lead to a solution:
