In iOS, is it possible to save hours, minutes, seconds into different integer variables from the current time?
Yes, you can:
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:(NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:[NSDate date]];
NSInteger hour = [components hour];
NSInteger minutes = [components minute];
NSInteger seconds = [components second];
