[英]iOS app shows notifications when in background but not foreground iphone 4s & os version 9.3
應用程序在不處於運行狀態,后台狀態時正在接收遠程通知,並使用本地攔截概念在前台狀態中接收通知(在獲取遠程通知時觸發本地通知)。 但是,當應用程序處於前台並且iOS版本為9.3時,它不會收到遠程通知。
我的代碼在這里:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSLog(@"Called");
NSLog(@"Response - > %@",userInfo);
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:1];
localNotification.alertBody = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"];
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = 0;
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
{
NSLog( @"Handle push from foreground" );
// custom code to handle push while app is in the foreground
NSLog(@"%@", notification.request.content.userInfo);
completionHandler(UNNotificationPresentationOptionAlert);
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler
{
NSLog( @"Handle push from background or closed" );
// if you set a member variable in didReceiveRemoteNotification, you will know if this is from closed or background
NSLog(@"%@", response.notification.request.content.userInfo);
NSInteger countNoti = [[[response.notification.request.content.userInfo valueForKey:@"aps"] valueForKey:@"badge"] integerValue];
if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive ) {
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:1];
localNotification.alertBody = [[response.notification.request.content.userInfo valueForKey:@"aps"] valueForKey:@"alert"];
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = countNoti;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
}
didReceiveRemoteNotification
調用,但未顯示通知。 謝謝。
我認為您尚未在AppDelegate文件中實現iOS9 PushNotification方法
Objective-C的
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
迅速
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any])
您可以在應用處於活動狀態時在上述功能中安排本地通知。 顯示通知。
