如何在AppDelegate.m中的openURL中提供多个源？

Question

I'm trying to handle both of Twitter and deep link in openURL, using ReactNative. The code below does not work, ending up go into if (LinkingHandled) even when handling Twitter.

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
  bool TwitterHandled = [[Twitter sharedInstance] application:application openURL:url options:options];
  bool LinkingHandled =[RCTLinkingManager application:application openURL:url options:options];
  if (TwitterHandled) {
    return TwitterHandled;
  }
  if (LinkingHandled) {
    return LinkingHandled;
  }
  return NO;
}

What is wrong with this? I'm new to ObjC.

Use } else if { so only Twitter goes if it gets handled, and 'linking' will only go if TwitterHandled is NO and LinkingHandled is YES.

This can be simplified into one expression:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
    return [Twitter.sharedInstance
            application:application
                openURL:url options:options] || 
           [RCTLinkingManager
            application:application 
                openURL:url
                options:options];
}

Switch to Swift if you can. 🙂
