Question

Here is my previous question about using date in objective-c. How to get hours, minutes and seconds with leading zeroes ?

Answer 1

Now that you precised that you want hours, minutes and seconds as strings, here is how to get them:

NSDateComponents *components = [[NSCalendar currentCalendar] components:NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit fromDate:[NSDate date]]; 

NSInteger hour= [components hour];   
NSInteger minute = [components minute];
NSInteger second = [components second];

NSString *hourString = [NSString stringWithFormat:@"%02d", hour];
NSString *minuteString = [NSString stringWithFormat:@"%02d", minute];
NSString *secondString = [NSString stringWithFormat:@"%02d", second];

The key is to use "%02d" when formatting, to guarantee that you get two digits.
