iOS 12 前台通知shouldAlwaysAlertWhileAppIsForeground崩潰問題

iOS12后，前台通知中

shouldAlwaysAlertWhileAppIsForeground不能使用了，如果還是

 [content setValue:@(YES) forKeyPath:@"shouldAlwaysAlertWhileAppIsForeground"]則會崩潰

 

解決辦法：

Appdelegate中添加：

//iOS 12
-(void) userNotificationCenter:(UNUserNotificationCenter*)center willPresentNotification:(UNNotification*)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
{
    completionHandler(UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionSound);
}

 

創建前台通知時不設置

shouldAlwaysAlertWhileAppIsForeground屬性。
