针对 iOS 目标的 CMake xib 到 nib 编译

Question

我的目标是 iOS（设备和模拟器）并设置 CMake 以添加捆绑包中所需的不同资源。“xib”文件给我带来了一些问题。如果我不采取进一步操作，iPhone/iPad 模拟器运行将失败并出现错误：

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''

捆绑包中缺少 NIB 文件。一个示例 (http://www.vtk.org/Wiki/CMake:OSX_InterfaceBuilderFiles) 显示，对于 OSX，您必须将 xib 文件编译为 nib 文件，并将这些文件作为构建后步骤添加到捆绑包中。所以我的猜测是 iOS 也有类似的情况。但我的问题是，...我在哪里添加编译好的 nib 文件？

我现在在 CMakeLists.txt 中执行此操作：

# 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()

但我并不真正信任编译步骤的“目的地”，尤其是对于模拟器而言。

有谁能做到这一点或者看看我做错了什么？

Answer 1

它应该与 CMake Xcode 生成器“正常工作”，将 *.xib 文件作为源添加到add_executable，然后将RESOURCE目标属性设置为 *.xib 文件列表。

如CMake/Tests/iOSNavApp/CMakeLists.txt文件中所示。

此技术应适用于 CMake 2.8.5 及更高版本以及 Xcode 4 及更高版本。
