iOS8 UILocalNotification不工作

我使用以下代码进行本地通知。但它不起作用。位置已成功更新，并已进入这些方法，但未触发通知。有什么想法吗

注意：当应用程序处于后台时，它会工作，但当应用程序关闭时，它不会工作

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]){
        [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
    }
    [[UIApplication sharedApplication] cancelAllLocalNotifications];
    // Override point for customization after application launch.
    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;

    return YES;
}

-(void) locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {
    if ([region isKindOfClass:[CLBeaconRegion class]]) {
        UILocalNotification *notification = [[UILocalNotification alloc] init];
        notification.alertBody = @"You are checked in";
        notification.soundName = @"Default";
        [[UIApplication sharedApplication] presentLocalNotificationNow:notification];
    }
}

你应该记住，只有当你的应用程序在后台时才会出现通知，而不是在前台。如果您在前台，请实现AppDelegate的

-application:didReceiveLocalNotification:

，并自己手动处理通知

UPD

如果你的应用程序甚至没有在后台运行，你的代码将不会被执行。查找（跟踪用户位置部分）可能的解决方案，以便要求系统通过事件启动您的应用程序，即使当前它不在内存中

Wen应用程序已关闭应用程序标识背景已调用，因此请输入此后台任务代码。并对本地通知进行分类

- (void)applicationDidEnterBackground:(UIApplication *)application 
{
       bgTask = [application beginBackgroundTaskWithName:@"MyTask" expirationHandler:^{
    // Clean up any unfinished task business by marking where you
    // stopped or ending the task outright.
    [application endBackgroundTask:bgTask];
    bgTask = UIBackgroundTaskInvalid;
}];

// Start the long-running task and return immediately.
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

    // Do the work associated with the task, preferably in chunks.

    [application endBackgroundTask:bgTask];
    bgTask = UIBackgroundTaskInvalid;
});
    ////  just u call the method want ever u want example

    [self notification];
}

- (void)notification
{ 
    UILocalNotification *notification = [[UILocalNotification alloc] init];
    notification.alertBody = @"You are checked in";
    notification.soundName = @"Default";
    [[UIApplication sharedApplication] presentLocalNotificationNow:notification];
}

我认为这对你很有帮助。

即使你的应用程序被从后台删除，本地通知也能起作用。但在您的情况下，您正在侦听location manager事件并在委托方法内触发本地通知。一旦终止应用程序，将不会触发location manager事件。因此，您的本地通知根本不会被触发。

当您的应用程序被终止时，信标监控仍将重新启动它-这是信标监控的一大优点

您只需在

应用程序：didFinishLaunchingWithOptions:

方法中重新启动监控。如果您这样做，导致应用程序启动的

didEnterRegion

事件将立即传递给代理，代理将触发通知

- (void)applicationDidEnterBackground:(UIApplication *)application 
{
       bgTask = [application beginBackgroundTaskWithName:@"MyTask" expirationHandler:^{
    // Clean up any unfinished task business by marking where you
    // stopped or ending the task outright.
    [application endBackgroundTask:bgTask];
    bgTask = UIBackgroundTaskInvalid;
}];

// Start the long-running task and return immediately.
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

    // Do the work associated with the task, preferably in chunks.

    [application endBackgroundTask:bgTask];
    bgTask = UIBackgroundTaskInvalid;
});
    ////  just u call the method want ever u want example

    [self notification];
}

- (void)notification
{ 
    UILocalNotification *notification = [[UILocalNotification alloc] init];
    notification.alertBody = @"You are checked in";
    notification.soundName = @"Default";
    [[UIApplication sharedApplication] presentLocalNotificationNow:notification];
}

Estimote有一个更详细的指南：

---

. 它使用EstMote SDK中的ESTBeaconManager、ESTBeaconManagerDelegate和ESTBeaconRegion类，但您可以简单地将它们替换为常规的核心位置类，以实现相同的效果。

我的情况是从

设置->通知->您的应用程序->允许通知

是的，您是对的。请看这篇文章。当应用程序关闭或终止时，我需要得到通知。@Idrees我已经编辑了关于您评论的答案是的，我已经在后台模式下检查了位置更新，但它仍然不起作用
