So, first of all. Use this Template to simplify the process.
Then, once you start your project, inside /@@PROJECTNAME@@/Resources/@@PROJECTNAME@@.plist:
<dict>
<key>cell</key>
<string>PSSwitchCell</string>
<key>default</key>
<true/>
<key>defaults</key>
<string>@@PACKAGENAME@@</string>
<key>key</key>
<string>key1</string>
<key>label</key>
<string>Switch Text 1</string>
</dict>
<dict>
<key>cell</key>
<string>PSSwitchCell</string>
<key>default</key>
<true/>
<key>defaults</key>
<string>@@PACKAGENAME@@</string>
<key>key</key>
<string>key1</string>
<key>label</key>
<string>Switch Text 1</string>
</dict>
Change the 'false' to 'true' to keep the switch automatically turned on.
