我正在使用本地通知,但我想在警报的邮件正文中放置一个图像.我怎样才能做到这一点？

我想要实现地理定位通知,如应用提醒.这就是我已经做过的事情:

在App代表中:

self.locationManager = [[[CLLocationManager alloc] init] autorelease]; /* don't leak memeory! */
[self.locationManager setDelegate:self];
[self.locationManager setDesiredAccuracy:kCLLocationAccuracyBest];

-(void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region
{

}

-(void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region
{

}

-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{

}

并且视图控制器中的这一个开始监视:

CLLocationCoordinate2D location2D = mapView.region.center; 
CLRegion *regionForMonitoring = [[CLRegion alloc] initCircularRegionWithCenter:location2D radius:1 identifier:@"RegionIdentifier"];
[[Utils getLocationManager] startMonitoringForRegion:regionForMonitoring];

现在我不知道我需要做些什么才能使用这些信息来发送本地通知.

我正在开发一个iOS应用程序,我必须得到本地通知,但是在应用程序状态不活动的情况下.当应用程序处于后台状态时,我成功收到通知.那么,当应用程序处于非活动状态时,是否可以获得本地通知？或者也许只有使用推送通知才有可能？

此致,亚美尼亚

如何将NSDate秒转换为秒？我需要它在几秒钟内,以便我可以添加30秒到日期,然后转换回来NSDate安排本地通知.任何更好的方法也是受欢迎的.

我是iOS技术的新手.我正在尝试使用UILocalNotification使用swift 2.0构建一个警报应用程序.当我点击按钮时,我从UIPickerView获取时间和日期.我也想显示通知和播放声音.但声音和通知都不起作用.请帮我!

@IBOutlet weak var myPickerView: UIDatePicker!

override func viewDidLoad() {
    super.viewDidLoad()
    myPickerView.date = NSDate()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


@IBAction func setAlarmClicked(sender: UIButton) {
    let dateFormater : NSDateFormatter = NSDateFormatter()
    dateFormater.timeZone = NSTimeZone.defaultTimeZone()
    dateFormater.timeStyle = .ShortStyle
    dateFormater.dateStyle = .ShortStyle

    let dateTimeString : NSString = dateFormater.stringFromDate(myPickerView.date)
    print("date is \(dateTimeString)")

    self.sheduleLocalNotificationWithDate(myPickerView.date)
}

@IBAction func cancelAlarmClicked(sender: UIButton) {

}

func sheduleLocalNotificationWithDate(fireDate : NSDate){
    let localNotification : UILocalNotification = UILocalNotification()
    localNotification.fireDate = …

我想在应用程序处于forground时显示通知.下面是我为新的usernotificationdelegate方法所做的代码.

在app委托中:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"10.0")) {

        //iOS 10 handling
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {
          if (!error) {
                 NSLog(@"request authorization succeeded!");
          } }];
     } 
}

#pragma mark - User notification delegate
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler {

    NSLog(@"willPresentNotification");
    NSLog(@"%@", notification.request.content.userInfo);
    completionHandler (UNNotificationPresentationOptionAlert);
}

这是我触发本地通知的方法

-(void) fireLocalNotification:(NSString *) message
{

    NSLog(@"fire Local Notification");
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"10.0")) {

        //Notification Content …

可以UILocalNotification存放NSUserDefaults吗？

我试图获取值但它总是返回null.

这是尝试获取值的方法

-(IBAction)doneClicked:(id)sender
{
    NSUserDefaults *prefx = [NSUserDefaults standardUserDefaults];
    UILocalNotification *oldNotifObj = [prefx objectForKey:@"NotificationObject"];
    NSLog(@"oldNotifObj = %@",oldNotifObj);

    NSLog(@"enable notification");
    if (oldNotifObj == nil)
    {
        [self addNotification];
        NSLog(@"add a new one");
    }
    else
    {
        //if notification exist, remove old one, and add new one.
        [self removeNotification:oldNotifObj];
        [prefx setObject:nil forKey:@"NotificationObject"];
        [self addNotification];
        NSLog(@"remove old notification and add a new one");
    }
}

这是addNotification方法

-(void)addNotification
{
    //set the notification
    UILocalNotification *localNotif = [[UILocalNotification alloc]init];
    localNotif.fireDate = …

我在我的设置"应用程序不在后台运行" info.plist,所以当用户点击主页按钮时,应用程序退出.

当我 [UIApplication -appWillTerminate:]打电话时,我会向系统安排64个本地通知,所有这些都是不重复的.

但在带有iOS6.0.1的iPhone4上花费了相当长的时间(6.17秒).当我查看时间分析器时,我发现曲线非常奇怪,它不占用太多CPU时间,但确实需要花费很多时间.

此外,当我查看调用树时,93%的时间花费在[UIApplication -scheduleLocalNotification:]图像中显示的时间范围内.为什么？

这是我生成通知的方式:

UILocalNotification *n = [[[UILocalNotification] alloc] init] autorelease];
n.alertBody = @"some body";
n.hasAction = YES;
n.alertAction = @"some action";
n.fireDate = @"some date";
n.repeatInterval = 0;
n.soundName = @"my sound"
n.userInfo = aDictionaryWithAStringAbount10CharacterLongAnd2NSNumber.
[self.notifications addObject:n];

这是我安排通知的方式:

-(void)endProxyAndWriteToSystemLocalNotification
{
        _proxying = NO;
        NSDate *dateAnchor = [NSDate date];

        NSEnumerator *enumerator = [self.notifications objectEnumerator];
        NSInteger i = 0;
        while (i < maxLocalNotifCount) {
            UILocalNotification *n = [enumerator nextObject];
            if (!d) { …

我有一个方法,使UILocalNotification存储:

- (void)save:(NSString *)program at:(NSDate*)date  {

    NSLog(@"date to save: %@", date);
   // NSLog(@"timezone: %@",[date descriptionWithLocale:[NSLocale systemLocale]]);


    UILocalNotification* localNotification = [[UILocalNotification alloc] init];

    NSLog(@"date to fire: %@", date);
    localNotification.fireDate = date;

    NSString *s=[program stringByAppendingString:@" is now on "];
    NSString *title=[s stringByAppendingString:channel];
    localNotification.alertBody = title;

    localNotification.alertAction = @"Show...";
    //localNotification.timeZone = [NSTimeZone localTimeZone];


    localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;

    NSLog(@"notification to save %@",localNotification);

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

    // Request to reload table view data
    [[NSNotificationCenter defaultCenter] postNotificationName:@"reloadData" object:self];

    // Dismiss the view controller …

我正在尝试以1天(24小时)的时间间隔显示本地通知并且其工作正常,但现在我想取消特定日期的通知.我试过(今天)这个,但它似乎没有用.我的通知仍然显示这是我为取消通知所做的工作:

let appNotification = appDelegate!.notification

UIApplication.sharedApplication().cancelLocalNotification(appNotification)

这是我如何安排通知appDelegate:

//scheduling notification

dateComp.year = 2015;
dateComp.month = 01;
dateComp.day = 20;
dateComp.hour = 21;
dateComp.minute = 05;
dateComp.timeZone = NSTimeZone.systemTimeZone()

notification.category = "FIRST_CATEGORY"
notification.alertBody = "my daily notiification ?"
notification.soundName = UILocalNotificationDefaultSoundName
notification.fireDate  = finalFireDate
notification.repeatInterval = NSCalendarUnit.Day

let dateNow = NSDate()
let noticalendar = NSCalendar.currentCalendar()
let hour = calendar.component(NSCalendarUnit.Hour, fromDate: dateNow)
UIApplication.sharedApplication().scheduleLocalNotification(notification)

我不知道为什么我不能取消通知有任何遗漏或做错的事,请告诉我.
