有预谋的通知

Question

是否可以将应用设置为在指定时间从自己发送通知？也许把它们排成队列？到目前为止，我不得不通过推送通知服务器，当我每周二早上发送消息时，这似乎过度杀戮。这也叫做什么（所以我可以在网上更好地研究它）

Answer 1

您可以安排这样的通知：

- (void)scheduleNotification
{
    //Cancel all previous Local Notifications
    [[UIApplication sharedApplication] cancelAllLocalNotifications];

    //Set new Local Notifications
    Class cls = NSClassFromString(@"UILocalNotification");
    if (cls != nil)
    {
        UILocalNotification *notif = [[cls alloc] init];
        //3 days
        notif.fireDate = [NSDate dateWithTimeInterval:60.0f*60.0f*24.0f*3.0f sinceDate:[NSDate date]];
        notif.timeZone = [NSTimeZone defaultTimeZone];
        notif.alertBody = @"Come Back Again! Lets blast All Zombie!";
        notif.alertAction = @"PLAY";
        notif.soundName = UILocalNotificationDefaultSoundName;
        notif.applicationIconBadgeNumber = 1;
        [[UIApplication sharedApplication] scheduleLocalNotification:notif];
        }    
}


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [application registerForRemoteNotificationTypes:
     UIRemoteNotificationTypeBadge |
     UIRemoteNotificationTypeAlert |
     UIRemoteNotificationTypeSound];

    [self scheduleNotification];
    ..
}
