我有本地通知的代码,我有一个scheduleNotification和clearNotification使用我自己的方法。这些是代码:
- (void)clearNotification {
[[UIApplication sharedApplication] cancelAllLocalNotifications];
}
- (void)scheduleNotification {
[reminderText resignFirstResponder];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
Class cls = NSClassFromString(@"UILocalNotification");
if (cls != nil) {
UILocalNotification *notif = [[cls alloc] init];
notif.fireDate = [[datePicker date] dateByAddingTimeInterval:-30];
notif.timeZone = [NSTimeZone defaultTimeZone];
notif.alertBody = @"Evaluation Planner";
notif.alertAction = @"Details";
notif.soundName = UILocalNotificationDefaultSoundName;
notif.applicationIconBadgeNumber = 1;
NSDictionary *userDict = [NSDictionary dictionaryWithObject:reminderText.text forKey:kRemindMeNotificationDataKey];
notif.userInfo = userDict;
[[UIApplication sharedApplication] scheduleLocalNotification:notif];
[notif release];
}
}
这些代码运行良好,但现在我想知道如何知道它将删除哪个通知对象。我想为通知创建一个ID,这意味着,一个ID相当于一个通知。但我不知道我应该在哪个方面做到这一点。另外,我需要找到一种方法将所有这些包括在一个plist中。
希望有人可以帮助我。感谢。答案 0 :(得分:12)
NSArray *notifications = [[UIApplication sharedApplication] scheduledLocalNotifications];
for (UILocalNotification *not in notifications) {
NSString *dateString=[not.userInfo valueForKey:@"EndDate"];
if([dateString isEqualToString:@"CompareString"])
{
[[UIApplication sharedApplication] cancelLocalNotification:not];
}
}
与我合作。
干杯..

(void)cancelLocalNotification:(NSString*)notificationID
{
// UILocalNotification *cancelThisNotification = nil;
// BOOL hasNotification = NO;
for (int j =0;j<[[[UIApplication sharedApplication]scheduledLocalNotifications]count]; j++)
{
UILocalNotification *someNotification = [[[UIApplication sharedApplication]scheduledLocalNotifications]objectAtIndex:j];
if([[someNotification.userInfo objectForKey:@"drdid"] isEqualToString:notificationID])
{
NSLog(@"id,notificationID(App) %@ %@ ",[someNotification.userInfo objectForKey:@"drdid"],notificationID);
NSLog(@"canceled notifications %@",someNotification);
[[UIApplication sharedApplication] cancelLocalNotification:someNotification];
}
}
}

我建议在UILocalNotification上使用userInfo属性,正如其他人所提到的那样。一个更简单的实现,接受的答案是:
for(UILocalNotification* notification in [[UIApplication sharedApplication]scheduledLocalNotifications])
{
if([[notification.userInfo objectForKey:@"notification_identifier"] isEqualToString:@"notification_001"])
{
[[UIApplication sharedApplication] cancelLocalNotification:notification];
}
}
像这样的for循环要简单得多。我不确定它是否或多或少是最优的,但它肯定更容易阅读,我认为你只有一些通知可以循环播放。
