Xcode 4：使用Git repo commit版本在每个构建上更新CFBundleVersion

我通过使用git标签为x和y(例如0.4)提供有意义的标记号来处理这个问题,然后通过脚本构建阶段,z获取自git describe返回的自上一个标记以来的提交数.

这是我从this one改编的脚本.它可以作为构建阶段直接添加到目标(sHell是/usr/bin/env ruby​​)：

# add git tag + version number to Info.plist
version = `/usr/bin/env git describe`.chomp

puts "raw version "+version
version_fancy_re = /(\d*\.\d*)-?(\d*)-?/
version =~ version_fancy_re
commit_num = $2
if ( $2.empty? )
commit_num = "0"
end
fancy_version = ""+$1+"."+commit_num
puts "compatible: "+fancy_version

# BACkup
source_plist_path = File.join(ENV['PROjeCT_DIR'],ENV['INFOPLIST_FILE'])
orig_plist = File.open( source_plist_path,"r").read;
File.open( source_plist_path+".bak","w") { |file| file.write(orig_plist) }

# put in CFBundLeversion key
version_re = /([\t ]+<key>CFBundLeversion<\/key>\n[\t ]+<String>).*?(<\/String>)/
orig_plist =~ version_re
bundle_version_String = $1 + fancy_version + $2
orig_plist.gsub!(version_re,bundle_version_String)

# put in CFBundleShortVersionString key
version_re = /([\t ]+<key>CFBundleShortVersionString<\/key>\n[\t ]+<String>).*?(<\/String>)/
orig_plist =~ version_re
bundle_version_String = $1 + fancy_version + $2
orig_plist.gsub!(version_re,bundle_version_String)

# write
File.open(source_plist_path,"w") { |file| file.write(orig_plist) }
puts "Set version String to '#{fancy_version}'"
