iOS other apps display their own APP when "open in other apps"

The requirements are as follows: open the file in other APPs, choose other more ways to open it, and then be able to see your own APP

1. Add: to the project’s info.plist file:

<key>CFBundleDocumentTypes</key>
	<array>
		<dict>
			<key>CFBundleTypeName</key>
			<string>xlsx</string>
			<key>LSHandlerRank</key>
			<string>Default</string>
			<key>LSItemContentTypes</key>
			<array>
				<string>public.content</string>
			</array>
		</dict>
		<dict>
			<key>CFBundleTypeName</key>
			<string>xls</string>
			<key>LSHandlerRank</key>
			<string>Default</string>
			<key>LSItemContentTypes</key>
			<array>
				<string>public.content</string>
			</array>
		</dict>
		<dict>
			<key>CFBundleTypeName</key>
			<string>pdf</string>
			<key>LSHandlerRank</key>
			<string>Default</string>
			<key>LSItemContentTypes</key>
			<array>
				<string>public.content</string>
			</array>
		</dict>
		<dict>
			<key>CFBundleTypeName</key>
			<string>docx</string>
			<key>LSHandlerRank</key>
			<string>Default</string>
			<key>LSItemContentTypes</key>
			<array>
				<string>public.content</string>
			</array>
		</dict>
		<dict>
			<key>CFBundleTypeName</key>
			<string>doc</string>
			<key>LSHandlerRank</key>
			<string>Default</string>
			<key>LSItemContentTypes</key>
			<array>
				<string>public.content</string>
			</array>
		</dict>
	</array>

There are two ways to add, one is to add in info.plistthe second is to add one by one directly in the , the effect is the sameSource Code

info - > Document Type

After adding it, you can see your own app by checking it in other apps. After the file is transferred, it is received in AppDelegate:

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
