微信分享功能怎么在自己的应用中判断是从微信跳转过来的？

从微信进入app的时候进入下面两个函数，我要怎么在这两个函数里判断是微信跳转过来的

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray<id<UIUserActivityRestoring>> * _Nullable))restorationHandler

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