Answer 1

To format the given "sourceDate" as "5:56 pm" for today, "yesterday" for any time yesterday, "January 16" for any day in the same year and "January 16, 2014". I am posting my own method.

sourceDate = //some date that you need to take into consideration


 NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitMinute | NSCalendarUnitHour | NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:[NSDate date]];
    NSDateComponents *sourceDateComponents = [[NSCalendar currentCalendar] components:NSCalendarUnitMinute | NSCalendarUnitHour | NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate: sourceDate];

    NSString* timestamp;

    NSDateFormatter *formatSourceDate   =   [NSDateFormatter new];
    [formatSourceDate setAMSymbol:@"AM"];
    [formatSourceDate setPMSymbol:@"PM"];

    //same day - time in h:mm am/pm
    if (components.day == sourceDateComponents.day) {
        NSLogInfo(@"time");
        [formatSourceDate setDateFormat:@"h:mm a"];
        timestamp = [NSString stringWithFormat:@"%@",[formatSourceDate stringFromDate:date]];
        return timestamp;
    }
    else if (components.day - sourceDateComponents.day == 1) {
        //yesterday
        timestamp = NSLocalizedString(@"Yesterday", nil);
        return timestamp;
    }
    if (components.year == sourceDateComponents.year) {
        //september 29, 5:56 pm
        [formatSourceDate setDateFormat:@"MMMM d"];
        timestamp = [NSString stringWithFormat:@"%@",[formatSourceDate stringFromDate:date]];
        return timestamp;
    }
    [formatSourceDate setDateFormat:@"MMMM d year"];
    timestamp = [NSString stringWithFormat:@"%@",[formatSourceDate stringFromDate:date]];
    return timestamp;

    NSLogInfo(@"Timestamp : %@",timestamp);
