我正在为Ipad和Iphone开发一个cordova应用程序，我需要iphone应用程序仅支持肖像和ipad应用程序，仅支持横向。现在我在config.xml文件中设置了<preference name="Orientation" value="portrait" />。这只会设置iphone的方向。无论如何，我可以在构建后在ios项目中执行任何操作时从配置文件中设置ipad方向。

Cordova不支持这种开箱即用的功能，但您可以在构建过程中使用钩子将代码插入iOS plist，以节省在项目构建后必须手动编辑它。
以下解决方案基于@djett this page上的帖子。但请注意，目前a bug in the Cordova 5.0.0 CLI导致自定义iOS方向设置在构建过程中被清除。
在你的配置xml中，添加：
<platform name="ios">
<config-file platform="ios" target="*-Info.plist" parent="UISupportedInterfaceOrientations">
<array>
<string>UIInterfaceOrientationPortrait</string>
</array>
</config-file>
<config-file platform="ios" target="*-Info.plist" parent="UISupportedInterfaceOrientations~ipad">
<array>
<string>UIInterfaceOrientationLandscapeLeft</string>
<string>UIInterfaceOrientationLandscapeRight</string>
</array>
</config-file>
</platform>
并将以下代码from here添加到{your_project} /hooks/after_prepare/update_platform_config.js：
#!/usr/bin/env node
/** This hook updates platform configuration files based on preferences and config-file data defined in config.xml.
Currently only the AndroidManifest.xml and IOS *-Info.plist file are supported.
Preferences:
1. Preferences defined outside of the platform element will apply to all platforms
2. Preferences defined inside a platform element will apply only to the specified platform
3. Platform preferences take precedence over common preferences
4. The preferenceMappingData object contains all of the possible custom preferences to date including the
target file they belong to, parent element, and destination element or attribute
Config Files
1. config-file elements MUST be defined inside a platform element, otherwise they will be ignored.
2. config-file target attributes specify the target file to update. (AndroidManifest.xml or *-Info.plist)
3. config-file parent attributes specify the parent element (AndroidManifest.xml) or parent key (*-Info.plist)
that the child data will replace or be appended to.
4. config-file elements are uniquely indexed by target AND parent for each platform.
5. If there are multiple config-file's defined with the same target AND parent, the last config-file will be used
6. Elements defined WITHIN a config-file will replace or be appended to the same elements relative to the parent element
7. If a unique config-file contains multiples of the same elements (other than uses-permssion elements which are
selected by by the uses-permission name attribute), the last defined element will be retrieved.
Examples:
AndroidManifest.xml
NOTE: For possible manifest values see http://developer.android.com/guide/topics/manifest/manifest-intro.html
<platform name="android">
//These preferences are actually available in Cordova by default although not currently documented
<preference name="android-minSdkVersion" value="8" />
<preference name="android-maxSdkVersion" value="19" />
<preference name="android-targetSdkVersion" value="19" />
//custom preferences examples
<preference name="android-windowSoftInputMode" value="stateVisible" />
<preference name="android-installLocation" value="auto" />
<preference name="android-launchMode" value="singleTop" />
<preference name="android-activity-hardwareAccelerated" value="false" />
<preference name="android-manifest-hardwareAccelerated" value="false" />
<preference name="android-configChanges" value="orientation" />
<preference name="android-theme" value="@android:style/Theme.Black.NoTitleBar" />
<config-file target="AndroidManifest.xml" parent="/*>
<supports-screens
android:xlargeScreens="false"
android:largeScreens="false"
android:smallScreens="false" />
<uses-permission android:name="android.permission.READ_CONTACTS" android:maxSdkVersion="15" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
</config-file>
</platform>
*-Info.plist
<platform name="ios">
<config-file platform="ios" target="*-Info.plist" parent="UISupportedInterfaceOrientations">
<array>
<string>UIInterfaceOrientationLandscapeOmg</string>
</array>
</config-file>
<config-file platform="ios" target="*-Info.plist" parent="SomeOtherPlistKey">
<string>someValue</string>
</config-file>
</platform>
NOTE: Currently, items aren't removed from the platform config files if you remove them from config.xml.
For example, if you add a custom permission, build the remove it, it will still be in the manifest.
If you make a mistake, for example adding an element to the wrong parent, you may need to remove and add your platform,
or revert to your previous manifest/plist file.
TODO: We may need to capture all default manifest/plist elements/keys created by Cordova along with any plugin elements/keys to compare against custom elements to remove.

我想通过配置更新我的方向，因为它始终是在构建日设置它的手动任务。我已经添加了这个插件：
然后我可以将这些添加到我的配置中，并且不必再担心它。
<platform name="ios">
<!-- Set orientation on iPhone -->
<config-file platform="ios" target="*-Info.plist" parent="UISupportedInterfaceOrientations">
<array>
<string>UIInterfaceOrientationPortrait</string>
<string>UIInterfaceOrientationPortraitUpsideDown</string>
</array>
</config-file>
<!-- Set orientation on iPad -->
<config-file platform="ios" target="*-Info.plist" parent="UISupportedInterfaceOrientations~ipad">
<array>
<string>UIInterfaceOrientationLandscapeLeft</string>
<string>UIInterfaceOrientationLandscapeRight</string>
</array>
</config-file>
</platform>
我也使用这个插件： Cordova-Screen-Orientation 非常灵活和更好的控制，允许您指定特定设备（xs，sm，md，lg），特定平台和不同页面的方向锁定，即。如果您的应用程序都是纵向的，但是当您转到视频页面时，您希望它们处于风景中。

不幸的是我无法使用edit-config和Cordova 7，但我可以使用cordova-custom-config插件。
cordova plugin add cordova-custom-config --save
然后将以下内容添加到config.xml中。请注意此插件的第5版的custom-config-file元素而不是config-file元素，以防止使用cordova解析config-file元素的conflicting。
<platform name="ios">
<custom-config-file mode="replace" parent="UISupportedInterfaceOrientations" target="*-Info.plist">
<array>
<string>UIInterfaceOrientationPortrait</string>
</array>
</custom-config-file>
<custom-config-file mode="replace" parent="UISupportedInterfaceOrientations~ipad" target="*-Info.plist">
<array>
<string>UIInterfaceOrientationLandscapeLeft</string>
<string>UIInterfaceOrientationLandscapeRight</string>
</array>
</custom-config-file>
...
</platform>

对于iOS Cordova应用程序，您可以使用cordova-custom-config插件，该插件非常易于使用，只需要在config.xml中进行更改。

可以尝试以下列方式封闭不同设备的方向 - （但尚未检查是否可行，只是一个狂野的线索）

<preference name="" value="" />
</platform>
<platform name="iPad">
