我想取消 UILocalnotification ,当我取消通知时,通知仍然被触发。我想知道我是否必须调用 appdelegate 中的任何委托方法来取消通知。我正在使用的代码正在正确执行。但是通知被触发了。我应该使用具有 removeObserver 方法的 NSNotification 中心来取消 uilocalnotification。
UILocalnotification 是否从应用程序或设备触发通知。
更新 - 这就是我安排通知的方式
-(UILocalNotification *)scheduleNotification :(int)remedyID
{
NSString *descriptionBody;
NSInteger frequency;
UILocalNotification *notif = [[UILocalNotification alloc] init];
NSLog(@"%d",remedyID);
descriptionBody =[[self remedyDetailsForRemedyID:remedyID] objectForKey:@"RemedyTxtDic"];
frequency = [[[self remedyDetailsForRemedyID:remedyID] objectForKey:@"RemedyFrequency"]intValue];
NSArray *notificationFireDates = [self fireDatesForFrequency:frequency];
for (NSDate *fireDate in notificationFireDates)
{
notif.timeZone = [NSTimeZone defaultTimeZone];
notif.repeatInterval = NSDayCalendarUnit;
notif.alertBody = [NSString stringWithString:descriptionBody];
notif.alertAction = @"Show me";
notif.soundName = UILocalNotificationDefaultSoundName;
notif.applicationIconBadgeNumber = 1;
notif.fireDate = fireDate;
NSDictionary *userDict = [NSDictionary dictionaryWithObjectsAndKeys:notif.alertBody, @"kRemindMeNotificationDataKey", [NSNumber numberWithInt:remedyID],kRemindMeNotificationRemedyIDKey,
nil];
notif.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:notif];
}
return notif;
}
取消通知
- (void)cancelNotification:(int)remedyId
{
NSArray *notifications = [[UIApplication sharedApplication] scheduledLocalNotifications];
NSLog(@"Cancelling... Before %d",[[[UIApplication sharedApplication]scheduledLocalNotifications]count]);
for (UILocalNotification *notification in notifications)
{
int notifRemedyId = [[notification.userInfo objectForKey:@"kRemindMeNotificationRemedyIDKey"]intValue];
NSLog(@"remedyID : %d",remedyId);
NSLog(@"notifyId : %d",notifRemedyId);
if (remedyId == notifRemedyId) {
[[UIApplication sharedApplication] cancelLocalNotification:notification];
}
}
NSLog(@"Cancelling... After %d",[[[UIApplication sharedApplication]scheduledLocalNotifications]count]);
}
