LocalNotification for iOS

Question

我正在我的iOS应用程序中实现iOS。实际上，在创建通知时，我有一个带有方法的实现：

-(void)setAlarmAction: (NSDate *) notificationDay days: (NSNumber *) day alert :  (NSNumber * ) priority  name:(NSString * ) nameNotification {

 NSDate *notificationDate = notificationDay;

 UILocalNotification *localNotification = [[UILocalNotification alloc] init];
 if (localNotification == nil) {
    return;
 }

 localNotification.fireDate = notificationDate;
 localNotification.timeZone = [NSTimeZone defaultTimeZone];

 localNotification.alertBody =  [NSString stringWithFormat: @"Quedan %@ dias" , day];
 localNotification.alertAction = @"Ver Documento";

 localNotification.soundName = UILocalNotificationDefaultSoundName;
 localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication]applicationIconBadgeNumber]+1; //aumenta en uno el numero de notificaciones

////////////
 NSDictionary *infoDictionary = [NSDictionary dictionaryWithObject:@"notification" forKey:nameNotification]; //1º que se guarda , 2º con que clave
 localNotification.userInfo = infoDictionary;
////////////
 NSData *data = [NSKeyedArchiver archivedDataWithRootObject:localNotification];
 [[NSUserDefaults standardUserDefaults] setObject:data forKey:nameNotification];

 [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

 // Get list of local notifications
 NSArray *localNotifications = [[UIApplication sharedApplication] scheduledLocalNotifications];

 for( UILocalNotification * local  in localNotifications) {

    NSLog(@"Notificacion: %@ fecha :%@",local.alertBody,local.fireDate.description);
 }

}

-(void) launchNotificacion:(Documento *)document  {

  self.txDate.text = document.text;

}

我希望应用程序在后台中运行，当它出现在tabBar上时，我可以将它推送到一个具体的视图中，并启动一些数据。我是在didFinishlaunchingWithOptions做的。

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

 //self.viewDocumentForm
 VTDocumentFormViewController *VTDocument = [[VTDocumentFormViewController alloc] initWithNibName:@"VTDocumentFormViewController" bundle:nil];

 UILocalNotification *notification = [launchOptions objectForKey:
                                     UIApplicationLaunchOptionsLocalNotificationKey];

 if (notification) {

   [self.window.rootViewController presentViewController: VTDocument animated:YES completion:nil];

   Documento *reminderDocument = [NSEntityDescription insertNewObjectForEntityForName:@"Documento" inManagedObjectContext:self.managedObjectContext];
   reminderDocument = [notification.userInfo objectForKey: key ];

    [self.viewDocumentForm launchNotificacion:reminderDocument]; 
    application.applicationIconBadgeNumber = notification.applicationIconBadgeNumber-1;
 }

// Override point for customization after application launch.
return YES;

}

但这不管用，我也不知道原因。拜托救救我。

只有当app在到达didFinishLaunchingWithOptions:之前被挂起/终止时，launchOptions中的UIApplicationLaunchOptionsLocalNotificationKey才会被调用。

如果你的应用程序只是在后台(而不是被杀死)或活动，你会被application:didReceiveLocalNotification:炒掉

另外，在您的didFinishLaunchingWithOptions:中，我看不到您在哪里注册了用户通知设置(用于iOS8)…小象：

if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]) {
    UIUserNotificationType types = UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge;

    UIUserNotificationSettings *mySettings =
    [UIUserNotificationSettings settingsForTypes:types categories:nil];

    [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];
}
