如何在alertview的按钮单击上调用贪睡功能

Question

我已经通过 uilocalnotifications 设置了警报。所以当我的应用程序在后台时，我的本地通知会显示 2 个按钮关闭和查看。当我的应用程序在前台时，它会显示和 alertview 有 2 个按钮、停止和贪睡。当单击停止按钮我希望我的闹钟应该停止，当单击贪睡按钮时我希望通知应该在 5 分钟后出现。这怎么可能。请帮我解决这个问题。谢谢。

this is my code :


//this is my controller class where i am setting my notification

- (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];
        notif.timeZone = [NSTimeZone defaultTimeZone];

        notif.alertBody = @"Did you forget something?";
        notif.alertAction = @"Show me";
        notif.soundName = UILocalNotificationDefaultSoundName;
        notif.applicationIconBadgeNumber = 1;

        NSInteger index = [scheduleControl selectedSegmentIndex];
        switch (index) {
            case 1:
                notif.repeatInterval = NSMinuteCalendarUnit;
                break;
            case 2:
                notif.repeatInterval = NSHourCalendarUnit;
                break;
            case 3:
                notif.repeatInterval = NSDayCalendarUnit;
                break;
            case 4:
                notif.repeatInterval = NSWeekCalendarUnit;
                break;
            default:
                notif.repeatInterval = 0;
                break;
        }

        NSDictionary *userDict = [NSDictionary dictionaryWithObject:reminderText.text
                                                forKey:kRemindMeNotificationDataKey];
        notif.userInfo = userDict;

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

Answer 1

当您单击贪睡按钮时，您会设置另一个本地通知。当您单击贪睡按钮时，您会调用另一个函数。在这里，您采用当前时间，并在触发日期中添加 5 分钟来设置它。

当您的通知即将到来时，您会在收到的通知委托方法中接收一个警报，然后单击警报按钮调用此函数

点击你的贪睡提醒点击你调用这个函数。

-(void)addNewNotification{
        UILocalNotification* localNotification = [[UILocalNotification alloc] init];               
        localNotification.alertBody =@"HI"
        localNotification.fireDate = [[NSDate date] dateByAddingTimeInterval:5*60];
        localNotification.timeZone = [NSTimeZone localTimeZone];
        localNotification.applicationIconBadgeNumber = localNotification.applicationIconBadgeNumber+1;
        localNotification.soundName = UILocalNotificationDefaultSoundName;
        [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
        [localNotification release];
        NSLog(@"%@",[[UIApplication sharedApplication] scheduledLocalNotifications]);
}

Answer 2

我认为你应该使用 alertview 委托方法，clickedAtIndex。 然后检查索引是否是您想要说的 1 用于贪睡，然后在 5 分钟后重复。

谢谢
