root.plist

I want to give placeholder for textfield of Settings bundle (Root.plist) is it possible?if yes how? Thanks in advance I'm afraid currently it's not possible - I was also trying to do that but can't seem to find any working solution. If that helps, the official docs where this should be placed are here . 来源： https://stackoverflow.com/questions/13757735/how-to-give-placeholder-for-textfield-of-settings-bundle-root-plist

I have a settings bundle in my app.. containing root.plist now i have a screen which contains a checkbox .. on pressing the check box i want to change the BOOL value for DefaultValue key of PSToggleSwitchSpecifier in the plist. Since its being done at runtime.. my question is that .. can the file be changed at runtime and if yes.. give an idea how to do it?? here is the plist: <plist version="1.0"> <dict> <key>PreferenceSpecifiers</key> <array> <dict> <key>DefaultValue</key> <string></string> <key>Key</key> <string>Username</string> <key>Title</key> <string>Username</string> <key>Type</key>
