- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
    return  [WXApi handleOpenURL:url delegate:self];
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    return [WXApi handleOpenURL:url delegate:self];
}

这两个方法都已经被弃用，

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options {
    return [WXApi handleOpenURL:url delegate:self];
}

应该加一个这个方法。
