[CMake] Interface Builder xib to nib compilation for iOS

[Daniel Dekkers]

Hi,

I'm targeting iOS (device and simulator) and setting up CMake to add the different resources needed in the bundle.
The "xib" file is giving me some problems.
If I take no further action, the iPhone/iPad simulator run fails with the error:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </Users/danieldekkers/Library/Application Support/iPhone Simulator/4.3.2/Applications/1C29638B-7593-4311-8F94-C8051AF90AD7/Discs.app> (loaded)' with name 'MainWindow''

A missing NIB file in the bundle. 
An example (http://www.vtk.org/Wiki/CMake:OSX_InterfaceBuilderFiles) shows that for OSX, you have to compile the xib files into nib files and add these to the bundle as a post-build step.
So my guess would be that something similar holds for iOS as well.
But my question is,... where do i add the compiled nib files?

I now do this in the CMakeLists.txt:

# We need to compile the interface builder *.xib files to *.nib files to add to the bundle
# Make sure we can find the 'ibtool' program. If we can NOT find it we skip generation of this project
FIND_PROGRAM( IBTOOL ibtool HINTS "/usr/bin" "${OSX_DEVELOPER_ROOT}/usr/bin" )
if ( ${IBTOOL} STREQUAL "IBTOOL-NOTFOUND" )
	MESSAGE( SEND_ERROR "ibtool can not be found" )
ENDIF()

# Compile the .xib files using the 'ibtool' program with the destination being the app package
FOREACH( xib ${RSRC_IOS_XIB_FILES} )
	ADD_CUSTOM_COMMAND( TARGET ${RT_APP_NAME} POST_BUILD
	COMMAND ${IBTOOL} --errors --warnings --notices --output-format human-readable-text 
		--compile 
		${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/${RT_APP_NAME}.app/Contents/Resources/${xib}.nib
		${RT_APP_ROOT}/rsrc/apple/ios/${xib}.xib
		COMMENT "Compiling ${RT_APP_ROOT}/rsrc/apple/ios/${xib}.xib")
ENDFOREACH()

But i don't really trust the "destination" of the compilation step, especially for the simulator.
Has anyone got this working?

Kind Regards,

Daniel Dekkers
