使用PGB，我们现在可以添加到info.plist文件。所以在你的config.xml中这样：

 < gap：config-file platform =iosparent =UISupportedInterfaceOrientations overwrite =true> 
< array> 
< string> UIInterfaceOrientationPortrait< / string> 
< / array> 
< / gap：config-file>阅读更多，在这里看到这个确切的例子：

I have a PhoneGap 3.1 application that I build remotely on PhoneGap Build.

In my app there is a single config.xml file at the root of the project. This file contains:
<preference name="orientation" value="default" />

However I would like to restrict the orientation to portrait mode in iOS.
I've randomly tried :
<preference gap:platform="ios" name="orientation" value="portrait" />

and
<gap:platform name="ios">
    <preference name="orientation" value="portrait" />
</gap:platform>

but none of these seem to work.

How can I set preferences for specific platforms?

With PGB we now have the ability to add to the info.plist file. So in your config.xml put this:
<gap:config-file platform="ios" parent="UISupportedInterfaceOrientations" overwrite="true">
   <array>
      <string>UIInterfaceOrientationPortrait</string>
   </array>
</gap:config-file>
