取消 UILocalNotification [英] Cancel UILocalNotification

问题描述

我的 UILocalNotification 有问题.

I have a problem with my UILocalNotification.

我正在使用我的方法安排通知.

I am scheduling the notification with my method.

- (void) sendNewNoteLocalReminder:(NSDate *)date  alrt:(NSString *)title
{
    // some code ...
    UILocalNotification *localNotif = [[UILocalNotification alloc] init]; 

    if (localNotif == nil)  
        return;

    localNotif.fireDate = itemDate; 
    localNotif.timeZone = [NSTimeZone defaultTimeZone];
    localNotif.alertAction = NSLocalizedString(@"View Details", nil); 
    localNotif.alertBody = title;
    localNotif.soundName = UILocalNotificationDefaultSoundName; 
    localNotif.applicationIconBadgeNumber = 0;

    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:stringID forKey:@"id"]; 
    localNotif.userInfo = infoDict; 

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotif]; 
    [localNotif release];
}

它工作正常，我正确地收到了通知.问题是我什么时候应该取消通知.我正在使用这种方法.

Its work fine and I'm correctly receiving the notification. The problem is when I should cancel the notification. Im using this method.

- (void) deleteNewNoteLocalReminder:(NSString*) reminderID noteIDe:(NSInteger)noteIDE
{
    [[UIApplication sharedApplication] cancelLocalNotification:(UILocalNotification *)notification ????  
}

我不知道在这里做什么，但我的问题是:

Im not sure what to do here, but my questions are:

我怎么知道我应该删除哪个 UILocalNotification 对象?
有没有办法列出所有通知?

How do I know which UILocalNotification object I should delete?
Is there a way to list all notifications?

我唯一拥有的是我应该删除哪个提醒的 ID.
我正在考虑将 UILocalNotification 对象保存在我的Note"对象中并以这种方式获取它，当我保存到我的 SQLite 数据库时序列化对象等等......有没有更聪明的方法?

The only thing I have is the ID of which reminder I should delete.
I was thinking about to save the UILocalNotification object in my "Note" object and get it that way, and when I saving to my SQLite database serialize the object and so on ... is there a smarter way?

推荐答案

Swift 5:

UNUserNotificationCenter.current().removePendingNotificationRequests(withIdentifiers: arrayContainingIdentifiers)
