This is my code Here i am selecting my date through date picker and saving date in userdefaults.</p> <pre><code>this is my timepickercontroller.m - (void)viewDidLoad { time = [[NSString alloc] init]; CGRect pickerFrame = CGRectMake(0,40,0,0); datePicker = [[UIDatePicker alloc] initWithFrame:pickerFrame]; datePicker.datePickerMode = UIDatePickerModeTime; datePicker.date = [NSDate date]; [datePicker addTarget:self action:@selector(convertDueDateFormat) forControlEvents:UIControlEventValueChanged]; [self.view addSubview:datePicker]; [datePicker release]; } -(void)convertDueDateFormat{ app = (StopSnoozeAppDelegate*)[[UIApplication sharedApplication]delegate]; app.timerdate = [self.datePicker date]; NSLog(@"picker date:%@",selecteddate); if ([[NSUserDefaults standardUserDefaults] valueForKey:@"time"]==nil) { [[NSUserDefaults standardUserDefaults] setObject:[NSDate date] forKey:@"time"]; [[NSUserDefaults standardUserDefaults] synchronize]; NSLog(@"%@",[[NSUserDefaults standardUserDefaults] objectForKey:@"time"]); } else { NSArray *array = [[NSUserDefaults standardUserDefaults] objectForKey:@"time"]; NSMutableArray *array_dates = [[NSMutableArray alloc] init]; for(int i =0;i&lt;[array count];i++) { [array_dates addObject:[array objectAtIndex:i]]; } [array_dates addObject:app.timerdate]; [[NSUserDefaults standardUserDefaults] setObject:array_dates forKey:@"time"]; [[NSUserDefaults standardUserDefaults] synchronize]; NSLog(@"%@",[[NSUserDefaults standardUserDefaults] objectForKey:@"time"]); } } this is the controller where i am setting notification -(IBAction)save{ dateFormatter = [[NSDateFormatter alloc]init]; [dateFormatter setDateFormat:@"hh:mm a"]; NSDate *currentime = [NSDate date]; currentcheck = [NSString stringWithFormat:@"%@",[dateFormatter stringFromDate:currentime] ]; NSLog(@"currenttime:%@",currentcheck); timepicker = [[TTimePickerController alloc]init]; if (app.timerdate == NULL &amp;&amp; interval == NULL &amp;&amp; newsound == NULL) { UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"UIAlertView" message:@"Set Date,interval,sound for alarm" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; alert = nil; } else { [self scheduleNotification]; [self saveInDatabase]; } } -(void)scheduleNotification { [[UIApplication sharedApplication]cancelAllLocalNotifications]; timepicker = [[TTimePickerController alloc]init]; NSDate *newtestdate = [[NSUserDefaults standardUserDefaults]objectForKey:@"time"]; NSLog(@"fireDate=%@", newtestdate); NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar]; NSDateComponents *dateComponents = [calendar components:NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit fromDate:newtestdate]; NSDateComponents *timeComponents = [calendar components:NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit fromDate:newtestdate]; NSDateComponents *dateComps = [[NSDateComponents alloc]init]; [dateComps setDay:[dateComponents day]]; [dateComps setMonth:[dateComponents month]]; [dateComps setYear:[dateComponents year]]; [dateComps setHour:[timeComponents hour]]; [dateComps setMinute:[timeComponents minute]]; [dateComps setSecond:[timeComponents second]]; itemDate = [calendar dateFromComponents:dateComps]; [dateComps release]; Class cls = NSClassFromString(@"UILocalNotification"); if (cls!= nil) { UILocalNotification *notif = [[cls alloc]init]; notif.fireDate = itemDate; [app.dateFormatter setDateFormat:@"hh:mm a"]; newstring = [app.dateFormatter stringFromDate:notif.fireDate]; NSLog(@"new fire date:%@",newstring); notif.timeZone = [NSTimeZone defaultTimeZone]; notif.alertBody = @"Alarm"; notif.alertAction = @"View"; notif.soundName = UILocalNotificationDefaultSoundName; notif.applicationIconBadgeNumber=1; notif.repeatInterval = 0; [[UIApplication sharedApplication]scheduleLocalNotification:notif]; [notif release]; } } </code></pre>
