iOS - Friendly NSDate format

Question

I need to display the date of posts in my app to the user, right now I do it in this format: \"Fri, 25 May\". How would I format an NSDate to read something like \"2 hours ago\"

Answer 1

Adding to the solution try this more simplified method

    NSDateComponents *today = [[NSCalendar currentCalendar] components:NSCalendarUnitDay|NSCalendarUnitHour|NSCalendarUnitMinute|NSCalendarUnitSecond fromDate:passed toDate:[NSDate date] options:0];
    NSTimeInterval interval = [[NSDate date] timeIntervalSinceDate:date];

    if (interval < 60) timestampString = [NSString stringWithFormat:@"%d seconds ago" ,today.second];
    else if (interval < 60 * 60) timestampString = [NSString stringWithFormat:@"%d minutes ago" ,today.minute];
    else if (interval < 60 * 60 * 24) timestampString = [NSString stringWithFormat:@"%d hours ago" ,today.hour];
    else timestampString = [NSString stringWithFormat:@"%d days ago" ,today.day];
