MAUI iOS - App should not enabled when selecting multiple files for sharing

Question

In iOS device, open Files -> select more than one files from the files section -> click on share icon -> MAUI app displayed for sharing.

When i select more than one files, My MAUI ios app should not display the app from sharing.

I have added CFBundleDocumentTypes in the maui app to allow only specific document types can be shared with the mobile app. I haven't done any specific coding for this.

Any inputs for resolving this issue would be helpful.

I assume you use share extension in MAUI. You could refer to NSExtensionActivationRule . That means what you need to do is to define your own NSExtensionActivationRule in the info.plist for your Share Extension project.

A small example, if you want to limit the max supprt number to 1 file, just set NSExtensionActivationSupportsFileWithMaxCount to 1 (in the share extension's info,plist),

<key>NSExtension</key>
<dict>
    <key>NSExtensionAttributes</key>
    <dict>
        <key>NSExtensionActivationRule</key>
            <dict>
                    <key>NSExtensionActivationSupportsFileWithMaxCount</key>
                    <integer>1</integer>
            </dict>
    </dict>
    <key>NSExtensionMainStoryboard</key>
    <string>MainInterface</string>
    <key>NSExtensionPointIdentifier</key>
    <string>com.apple.share-services</string>
</dict>

For more info, you may also refer to Apple docs at App Extension Programming about NSExtensionActivationRule.

Hope it helps!
