To get the time from datepicker use ,
要从 datepicker 使用获取时间，
NSDateFormatter *outputFormatter = [[NSDateFormatter alloc] init];
[outputFormatter setDateFormat:@"HH:mm"]; //24hr time format
NSString *dateString = [outputFormatter stringFromDate:self.myDatePicker.date];
[outputFormatter release];
To do a functionality at particular time daily use UILocalNotification.
要每天在特定时间执行功能，请使用UILocalNotification。
Set the repeatInterval as NSDayCalendarUnit.
将repeatInterval 设置为NSDayCalendarUnit。
And in the delegate to handling the UILocalNotification code your method.
并在委托中处理 UILocalNotification 代码您的方法。
NOTE:This method will be execute only when the user accepts the Local notification.
