如何在iOS中的特定时间触发每日本地通知

我想获得每日通知，为此，我已经GOOGLE了，我从这个iPhone得到了一些解决scheme：每日本地通知，但我无法正确识别

NSCalendar *calendar = [NSCalendar currentCalendar]; NSDateComponents *components = [[NSDateComponents alloc] init]; [components setDay: 3]; [components setMonth: 7]; [components setYear: 2012]; [components setHour: 6]; [components setMinute: 0]; [components setSecond: 0]; [calendar setTimeZone: [NSTimeZone defaultTimeZone]]; NSDate *dateToFire = [calendar dateFromComponents:components]; 

假设当前时间是3:13，当前date是20-11-2014在这个我想在3:14，20-11-2014时间设置本地通知任何人都可以请帮助我，因为我试过以下的事情，但不工作

  [components setDay: 20]; [components setMonth: 11]; [components setYear: 2014]; [components setHour: 15]; [components setMinute: 14]; [components setSecond: 0];

 NSDate* now = [NSDate date] ; NSDateComponents* tomorrowComponents = [NSDateComponents new] ; tomorrowComponents.day = 1 ; NSCalendar* calendar = [NSCalendar currentCalendar] ; NSDate* tomorrow = [calendar dateByAddingComponents:tomorrowComponents toDate:now options:0] ; NSDateComponents* tomorrowAt7AMComponents = [calendar components:(NSEraCalendarUnit|NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit) fromDate:tomorrow] ; tomorrowAt7AMComponents.hour = 7 ; NSDate* tomorrowAt7AM = [calendar dateFromComponents:tomorrowAt7AMComponents] ; localnotification.fireDate = tomorrowAt7AM;
