我需要在我的应用的Info.plist中排除特定的密钥,如果它们在另一个哈希中找到的话。目前我可以像这样访问Info.plist中的各个键
setting4Str = `/usr/libexec/PlistBuddy -c \"print :MySettingsDict:setting4" {settings_file}`
我可以在plist字典中的这个键上设置“setting 4 text”字符串...
但是,我希望能够遍历此MysettingsDict的所有键。有没有人有方法将iOS XML plist转换为ruby Dictionary?

为那些想要解析二进制 Info.plist的人添加。
info_plist = File.read("Info.plist") # read binary plist
IO.popen('plutil -convert xml1 -r -o - -- -', 'r+') {|f|
f.write(info_plist)
f.close_write
info_plist = f.read # xml plist
}
现在info_plist是一个xml字符串。要快速提取一个属性,可以使用正则表达式:
app_bundle = info_plist.scan(/<key>CFBundleIdentifier<\/key>\s+<string>(.+)<\/string>/).flatten.first

使用Nokogiri Gem解析xml,然后将其输出为ruby哈希值。
这是另一个stackoverflow answer,它提供了一个示例,如果文档不够。

如果您正在寻找宝石,至少有两种选择:
plist
是用纯 Ruby 编写的,而 plist_lite
是用 C 编写的。
如果您关心性能,请使用 plist_lite
,它比 plist
快 5 倍以上。如果您需要一些丰富的功能,例如编码/解码非原始数据类型或格式,请使用 plist
。
plist_lite
的使用require 'plist_lite'
plist = PlistLite.dump({foo: 'bar', ary: [1,2,3], time: Time.at(0)})
# => "<?xml version=\"1.0\" encoding=\"UTF-8\"?><!DOCTYPE plist PUBLIC \"-//Apple//DTD PLIST 1.0//EN\" \"http://www.apple.com/DTDs/PropertyList-1.0.dtd\"><plist version=\"1.0\"><dict><key>foo</key><string>bar</string><key>ary</key><array><integer>1</integer><integer>2</integer><integer>3</integer></array><key>time</key><date>1970-01-01T00:00:00Z</date></dict></plist>"
PlistLite.load(plist)
# => {"foo"=>"bar", "ary"=>[1, 2, 3], "time"=>1970-01-01 00:00:00 UTC}
plist
的使用result = Plist.parse_xml('path/to/example.plist')
result.class
=> Hash
"#{result['FirstName']} #{result['LastName']}"
=> "John Public"
result['ZipPostal']
=> "12345"
