Эй, ребята, еще вопрос!
Еще раз я хотел бы заявить, что я новичок в этом, и поэтому моя способность понимать язык Objective C и приложение XCode ограничена! Так что Ваша помощь действительно и очень ценится!
Я создал приложение обратного отсчета, которое показывает, когда радиостанция будет запущена, обратный отсчет работал отлично и обновлялся в режиме реального времени раз в секунду, затем я вставил его в «If-Statement», чтобы, когда запуск станции прибывает, отсчет исчезает, но теперь мой отсчет не обновляется в режиме реального времени, он просто остается статичным.
Вот мой код:
- (void)viewDidAppear:(BOOL)animated {
self.today = [NSDate date];
NSDateFormatter *dateformatter = [[NSDateFormatter alloc] init];
[dateformatter setDateFormat:@"MM/dd/yyyy hh:mm:ss"];
NSString *launchDay = [[NSString alloc] initWithString:@"11/26/2010 11:59:59"];
NSDate *currentDate = [dateformatter dateFromString:launchDay];
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
int unitFlags = NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit;
NSDateComponents *components = [gregorian components:unitFlags fromDate:today toDate:currentDate options:0];
if ([today timeIntervalSinceDate:currentDate] <= 0 ){
self.today = [NSDate date];
NSDateFormatter *dateformatter = [[NSDateFormatter alloc] init];
[dateformatter setDateFormat:@"MM/dd/yyyy hh:mm:ss"];
countdownLabel.text = [NSString stringWithFormat:@"%02d:%02d:%02d:%02d", components.day, components.hour, components.minute, components.second ];
self.timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(updateLabel) userInfo:nil repeats:YES];
[self updateLabel];
days.text = @"Days";
hours.text = @"Hours";
mins.text = @"Mins";
secs.text = @"Secs";
until.text = @"Until XtremeFM Launch!";
}
else {
countdownLabel.text =@"XtremeFM is LIVE";
}
}
Ребята, любая помощь очень ценится, и я действительно надеюсь, что кто-то там может мне помочь!
Спасибо, ребята,

Видите ли, у меня был анимирован (BOOL) ViewDidAppear, но я не уверен, как добавить это в оператор if (Noob)
