当我从dateTimePicker.date获取时间/日期时,通知工作,但是当我用dateFromString触发日期时,通知不起作用.

代码:

-(IBAction)alarmSetButtonTapped:(id)sender {

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.locale = [NSLocale systemLocale];
dateFormatter.timeStyle = NSDateFormatterShortStyle;
dateFormatter.dateStyle = NSDateFormatterShortStyle;

NSString *tmp = @"2012-09-05 10:19";
[dateFormatter setDateFormat: @"yyyy-MM-dd HH:mm"];
[dateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];

NSDate *dateFromString = [dateFormatter dateFromString: tmp];
NSLog(@"Alarm TMP %@", dateFromString);
[dateFormatter release];


[self scheduleLocalNotificationWithDate:dateFromString];
[self presentMessage:@"Alarm set"];

};

请你帮帮我？

编辑:

-(void) scheduleLocalNotificationWithDate:(NSDate *)fireDate {

UILocalNotification *notification = [[UILocalNotification alloc] init];

notification.fireDate = fireDate;
notification.alertBody = @"Time to wake up";
notification.soundName = @"clock.mp3";

[[UIApplication sharedApplication] scheduleLocalNotification:notification];

[notification release];
}

我通过解析"fmt stream map"来获取Stream URL,

问题是如果我的视频持续时间不到1小时,我会得到这个:

{
"comment_count" = 1;
description = "";
"dislikes_num" = 0;
duration = "54:46";
"encrypted_id" = WWjNEyHrNsk;
"fmt_stream_map" =     (
            {
        "fallback_host" = "tc.v7.cache6.c.youtube.com";
        itag = 22;
        quality = hd720;
        type = "video/mp4; codecs=\"avc1.64001F, mp4a.40.2\"";
