避免在应用程序处于前台时显示通知警报

Question

嗨，我使用这个 UNUserNotificationCenterDelegate 来避免应用程序在前台使用此功能时的警报通知

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler  API_AVAILABLE(ios(10.0)){
    completionHandler(UNNotificationPresentationOptionAlert);
}

但我收到的通知同时包含警报和横幅选项如何在应用程序处于前台时删除警报？

Answer 1

您必须在 willPresent 方法中应用条件，以检查 App 的状态，如果 State 是 UIApplecationStateForeGround 则什么都不做，否则它们将遵循 UNNotificationPresentationOptionAlert。

Answer 2

我发现了如何修复一个信号初始化的选项以避免显示警报

[OneSignal initWithLaunchOptions:launchOptions appId:@"YOURE_KEY" handleNotificationReceived:nil handleNotificationAction:nil
                            settings:@{kOSSettingsKeyInAppAlerts:@NO}];

要显示为横幅，您必须添加此代码

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler  API_AVAILABLE(ios(10.0)){
    completionHandler(UNNotificationPresentationOptionAlert);
}
