AppDelegate.m for both FBSDK and LinkingManager

Question

To use FBSDK I need this snippet in app delegate

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url 
    sourceApplication:(NSString *)sourceA         


        

Answer 1

Of course, you can implement this method only once in your AppDelegate.

[[FBSDKApplicationDelegate... and [RCTLinkingManager... both return a BOOL.

You can put both snippets in the same method. I would suggest to return YES, if both [RCTLinkingManager... and [[FBSDKApplicationDelegate... return YES. Otherwise, return NO.

It could look like this:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url 
    sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

  BOOL handledFB = [[FBSDKApplicationDelegate sharedInstance] application:application
    openURL:url
    sourceApplication:sourceApplication
    annotation:annotation
  ];

  BOOL handledRCT = [RCTLinkingManager application:application openURL:url sourceApplication:sourceApplication annotation:annotation];

  return handledFB || handledRCT;
}

I can't guarantee, that you can use FBSDKApplicationDelegate and RCTLinkingManager in the same app, because I have never worked with this. But your code should at least compile.
