How do I prevent Alert when App is on Foreground w

问题:

When my app is in the foreground, there is a alert that appears. How do I prevent this from appearing when receiving push notifications?

回答1:

In your didFinishLaunchingWithOptions method of AppDelegate you have to add kOSSettingsKeyInAppAlerts = NO

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

回答2:

For Swift 3.0

// Initialize OngeSignal with Settings for Push Notifications
    OneSignal.initWithLaunchOptions(launchOptions, appId: Constants.OneSignalAppID, handleNotificationReceived: nil, handleNotificationAction: {
        (result) in
        // Do Something with Notification Result
    }, settings: [kOSSettingsKeyInFocusDisplayOption : OSNotificationDisplayType.none.rawValue])

By default OneSignal shows notifications as alert dialogs when the app is infocus. To change this pass kOSSettingsKeyInFocusDisplayOption with the value OSNotificationDisplayTypeNotification or OSNotificationDisplayTypeNone to settings on initWithLaunchOptions.

I achieved it this way. Add the following code in your AppDelegate didFinishLaunchingWithOptions

OneSignal.inFocusDisplayType = OSNotificationDisplayType.none

on last line in

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {

OneSignal.inFocusDisplayType = OSNotificationDisplayType.none
return true }

we have these 3 options

public enum OSNotificationDisplayType : UInt {


/*Notification is silent, or app is in focus but InAppAlertNotifications are disabled*/
case none


/*Default UIAlertView display*/
case inAppAlert


/*iOS native notification display*/
case notification
}
