如何创建提醒一段时间,如在iPhone中30分钟提醒我

Question

嗨,我正在处理提醒申请.

我需要在特定时间后显示提醒警报.

但当时我们没有设置日期选择器.

就像我有一个按钮'提醒10分钟'

-(IBAction)ReminderClick:(id)sender
{
}

当用户按下按钮时,10分钟后需要显示警告.

您需要使用UILocalNotification来实现此功能代码

UIApplication* app = [UIApplication sharedApplication];
        UILocalNotification* notifyAlarm = [[UILocalNotification alloc] init];

        NSDate *date1=[fire dateByAddingTimeInterval:60];
        notifyAlarm.fireDate = date1;
        notifyAlarm.timeZone = [NSTimeZone defaultTimeZone];
        //notifyAlarm.timeZone = [NSTimeZone defaultTimeZone];
        notifyAlarm.repeatInterval =NSWeekCalendarUnit ;
        notifyAlarm.soundName =soundString;
        notifyAlarm.alertBody =snoozeBody;
        notifyAlarm.userInfo=snoozeDict;
        //notifyAlarm.alertLaunchImage=@"in.png";
        [app scheduleLocalNotification:notifyAlarm];
