CMake 生成带有本地化的 xcode 项目

Question

We've are developing our OSX project using cMake as a tool to create the Xcode project.

However, it turns out we now need some localization, for which we need both English and German .xib files (or .strings to generate them, that's not the important bit).

We have the files in the right place and correctly created, but when cMake generates the project, the files are inserted into the Xcode project as two completely separate and independent files, such as:

Foo.xib Foo.xib

Instead of two "sub-files" under the same name:

Foo.xib - Foo.xib (English) - Foo.xib (German)

If i drag and drop the xib's that are in en.lproj and sv.lproj directly to the resources folder in the project explorer: Xcode automatically detects that this is some different languages of the same UI, hence the languages are added in the project settings automatically. Also the xibs get a MainMenu.xib group in the project explorer three, consisting of both the languages.

I try to add the localized xib's to the project through cmake. They get added to the resources folder but not as identified localizations, I only get two xibs in the project explorer three no localization no connection between them.

How can I make the localization work through cmake generation?

set(CEFCLIENT_RESOURCES_MAC_ENGLISH_LPROJ_SRCS_MACOSX
  mac/en.lproj/MainMenu.xib
  )

  set(CEFCLIENT_RESOURCES_MAC_SWEDISH_LPROJ_SRCS_MACOSX
  mac/sv.lproj/MainMenu.xib
  )

set(CEFCLIENT_RESOURCES_SRCS
  ${CEFCLIENT_RESOURCES_MAC_SRCS}
  ${CEFCLIENT_RESOURCES_MAC_ENGLISH_LPROJ_SRCS}
  ${CEFCLIENT_RESOURCES_MAC_SWEDISH_LPROJ_SRCS}
  ${CEFCLIENT_RESOURCES_RES_SRCS}
  )

Is there a way to generate the Xcode projects through cmake with the .lproj bundles working?

Answer 1

We just did this ourselves. Unfortunately the solution is not pretty. I ended up writing my own python script using mod_pbxproj to modify the xcode project after cmake generated it. If you can get away with using a regular xcode project instead of a cmake generated one, I think you are better off. What you have to do to make XCode recognize a set of files as localizations is pretty complex.

You can find an example of handling xib files for Xcode project here: https://github.com/open-eid/updater/blob/master/CMakeLists.txt .

Summary: one can use custom command + set MACOSX_PACKAGE_LOCATION property on resulting nib :

add_custom_command( OUTPUT MainMenu.nib
    COMMAND ibtool --errors --warnings --notices --output-format human-readable-text
        --compile MainMenu.nib ${CMAKE_CURRENT_SOURCE_DIR}/mac/en.lproj/MainMenu.xib
)
set_source_files_properties( MainMenu.nib
    PROPERTIES MACOSX_PACKAGE_LOCATION Resources/en.lproj )
