loadFilenameLookupDictionaryFromFile 调用出错

Cocos2d-x
#1

看到 loadFilenameLookupDictionaryFromFile 有 tolua 出来，我想用它来解析 plist

但是

CCFileUtils:sharedFileUtils():loadFilenameLookupDictionaryFromFile("versionFilePath.plist")

还是会出错

versionFilePath.plist 就是 CCFileUtils.h 里的例子也不行


<?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>filenames</key>
    <dict>
      <key>sounds/click.wav</key>
      <string>sounds/click.caf</string>
      <key>sounds/endgame.wav</key>
      <string>sounds/endgame.caf</string>
      <key>sounds/gem-0.wav</key>
      <string>sounds/gem-0.caf</string>
    </dict>
    <key>metadata</key>
    <dict>
      <key>version</key>
      <integer>1</integer>
    </dict>
  </dict>
</plist>

报错信息，我截图了

求帮助，谢谢
