在后台时不调用UILocalNotification

Question

当应用处于后台且处于活动状态时，我尝试触发UILocalNotification。我使用以下内容：

在App Delegate中我想＆＃34;赶上＆＃34;通知回调（未被调用）：

- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo{

    NSLog(@"recieve-old-notif-here");

}

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{


    NSLog(@"recieve-old-notif");
}

以下是我如何宣布本地通知：

NSString *strToShow = [NSString stringWithFormat:@"Время вставать"];


UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:15];

notification.alertBody = strToShow;
notification.timeZone = [NSTimeZone defaultTimeZone];
notification.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];

请注意我已经通过iOS 10通知完成了该任务，但我想在旧版设备上支持此功能。

所以，我的委托方法假设要调用，但它们没有，为什么？

Answer 1

将以下代码添加到委托中的didFinishLaunchingWithOptions方法：

ifdef __IPHONE_8_0

//Right, that is the point
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];

否则

//register to receive notifications
UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];

ENDIF

以及委托方法;

#ifdef __IPHONE_8_0
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
    //register to receive notifications
    [application registerForRemoteNotifications];
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler
{
    //handle the actions
    if ([identifier isEqualToString:@"declineAction"]){
    }
    else if ([identifier isEqualToString:@"answerAction"]){
    }
}
#endif
