查找应用程序已经设置的本地通知列表
我的应用程序允许用户在将来设置一些提醒。 当应用程序启动时，我想知道什么提醒（通知）已经设置。
我可以读回已设定的通知，还是需要将其存储在我的应用程序中（例如Core Data或Plist）？
UIApplication有一个名为scheduledLocalNotifications的属性，您可以使用它。
斯科特是正确的。
UIApplication的属性scheduledLocalNotifications
代码如下：
NSMutableArray *notifications = [[NSMutableArray alloc] init]; [notifications addObject:notification]; app.scheduledLocalNotifications = notifications; //Equivalent: [app setScheduledLocalNotifications:notifications];
UIApplication *app = [UIApplication sharedApplication]; NSArray *eventArray = [app scheduledLocalNotifications]; for (int i=0; i<[eventArray count]; i++) { UILocalNotification* oneEvent = [eventArray objectAtIndex:i]; NSDictionary *userInfoCurrent = oneEvent.userInfo; NSString *uid=[NSString stringWithFormat:@"%@",[userInfoCurrent valueForKey:@"uid"]]; if ([uid isEqualToString:uidtodelete]) { //Cancelling local notification [app cancelLocalNotification:oneEvent]; break; } }
NSArray *arrayOfLocalNotifications = [[UIApplication sharedApplication] scheduledLocalNotifications] ; for (UILocalNotification *localNotification in arrayOfLocalNotifications) { if ([localNotification.alertBody isEqualToString:savedTitle]) { NSLog(@"the notification this is canceld is %@", localNotification.alertBody); [[UIApplication sharedApplication] cancelLocalNotification:localNotification] ; // delete the notification from the system } }

对于Swift 3.0
let center = UNUserNotificationCenter.current() override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) center.getPendingNotificationRequests { (notifications) in print("Count: \(notifications.count)") for item in notifications { print(item.content) } } }
@Scott Berrevoets给出了正确的答案。 要实际列出它们，列举数组中的对象很简单：
[[[UIApplication sharedApplication] scheduledLocalNotifications] enumerateObjectsUsingBlock:^(UILocalNotification *notification, NSUInteger idx, BOOL *stop) { NSLog(@"Notification %lu: %@",(unsigned long)idx, notification); }];
Swift 3.0.2：
UIApplication.shared.scheduledLocalNotifications
在Swift中，查看当前在控制台中打印的所有本地通知：
print(UIApplication.sharedApplication().scheduledLocalNotifications)
在iOS 10 ，使用新的UserNotifications框架：
UNUserNotificationCenter.current().getPendingNotificationRequests { (notificationRequests) in print("Requests: \(notificationRequest)") }
