To Accomplish this firstly you need to goto your Info.Plist file and add some properties in Icon-File that is

<key>CFBundleIcons</key>
    <dict>
        <key>CFBundleAlternateIcon</key>
        <dict>
            <key>first_icon</key>
            <dict>
                <key>CFBundleIconFile</key>
                <array>
                    <string>first_icon.png</string>
                </array>
            </dict>
            <key>second_icon</key>
            <dict>
                <key>CFBundleIconFile</key>
                <array>
                    <string>second_icon.png</string>
                </array>
            </dict>
        </dict>
        <key>CFBundlePrimaryIcon</key>
        <dict>
            <key>CFBundleIconFiles</key>
            <array>
                <string></string>
            </array>
            <key>UIPrerenderedIcon</key>
            <false/>
        </dict>
        <key>UINewsstandIcon</key>
        <dict>
            <key>CFBundleIconFiles</key>
            <array>
                <string></string>
            </array>
            <key>UINewsstandBindingType</key>
            <string>UINewsstandBindingTypeMagazine</string>
            <key>UINewsstandBindingEdge</key>
            <string>UINewsstandBindingEdgeLeft</string>
        </dict>
    </dict>

Now you need to configure settings in your AppDelegate file

    - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{

      dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

        NSDictionary *notificationData = [[PushNotificationManager pushManager] getCustomPushDataAsNSDict:userInfo];
        NSString * notiIcon = [notificationData objectForKey:@"newIcon"];
        if([notiIcon isEqualToString:@"nil"])
          notiIcon = nil;

        NSLog(@"icon is: %@", notiIcon);

        [[UIApplication sharedApplication] setAlternateIconName:notiIcon completionHandler:^(NSError * _Nullable error) {
          NSLog(@"Set icon error = %@", error.localizedDescription);
        }];
      });

now from any dashboard you send the notification to the app goto that and there would be and option named Action or something like send Custom data send a key-value pair in code we are using key 'newIcon' so send it like that

{"newIcon":"first_icon"}

now when you'll send the notification with iconName that will appear.

This will Work..
