AppDelegate.m for both FBSDK and LinkingManager - ios

Question

To use FBSDK I need this snippet in app delegate
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
BOOL handled = [[FBSDKApplicationDelegate sharedInstance] application:application
openURL:url
sourceApplication:sourceApplication
annotation:annotation
];
// Add any custom logic here.
return handled;
}
To use LinkingManager I need this snippet in app delegate
#import "RCTLinkingManager.h"
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
return [RCTLinkingManager application:application openURL:url
sourceApplication:sourceApplication annotation:annotation];
}
They're obviously duplicates. How do I combine the two so both libraries work?
I don't know any Objective-C

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.

Wow, exactly what I was looking for! The accepted answer works great, except for a slight variation, since my FBSDK implementation is different (newer?). Because it uses:
options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
I just tried to use the same parameters as FBSDK, and it works!
sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
annotation:options[UIApplicationOpenURLOptionsAnnotationKey]
Full method:
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
BOOL handledFB = [[FBSDKApplicationDelegate sharedInstance] application:application
openURL:url
sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
annotation:options[UIApplicationOpenURLOptionsAnnotationKey]
];
BOOL handledRCT = [RCTLinkingManager application:application
openURL:url
sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
annotation:options[UIApplicationOpenURLOptionsAnnotationKey]
];
return handledFB || handledRCT;
}

For those who are using RNFirebase Linking:
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
BOOL handledFB = [[FBSDKApplicationDelegate sharedInstance]
application:application
openURL:url
sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
BOOL handledRCT = [RCTLinkingManager application:application openURL:url options:options];
if (!handledRCT) {
handledRCT = [[RNFirebaseLinks instance] application:application openURL:url options:options];
}
return handledFB || handledRCT;
}
