Changing MyApp-Info.plist gives an error

I've added this lines to my app .plist using TextEdit. I would enable iTunes file sharing with:

<key>UIFileSharingEnabled</key>
<string>YES<string/>

It results in this error: "couldn't parse contents of '/Users/me/Desktop/M开发者_JAVA百科yApp/MyApp-Info.plist': Encountered unexpected character s on line 31"

I wrote it after the other keys and before

</dict>

change <string/> to </string> and you should be good
