Extra Credit Adapting Data for Display

This extra credit asks for displaying the age of the post. I am able to show the age of the post in months ago, weeks ago, days ago, hrs ago. It seemed a little verbose. Just wanted to ask if there was simpler way of doing the same. I create a method in the BlogPost class that returns a string of the age, and then call that in the controller. '''objective-c -(NSString*) ageOfThePost { //difference bettween today's date and blogPost date

//change blog post date to date
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
NSDate *blogDate = [dateFormatter dateFromString:self.date];
//For difference
NSCalendar *gregorianCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *today=[NSDate date];
unsigned int unitFlags = NSMonthCalendarUnit | NSWeekCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit;
NSDateComponents *dateComp = [gregorianCalendar components:unitFlags fromDate:blogDate toDate:today options:0 ];
NSString *ageUnits=nil;
NSInteger age;

//Age
if([dateComp month]>0){
    age = [dateComp month];
    ageUnits=@"months ago";
} else if ([dateComp week]>0){
    age = [dateComp week];
    ageUnits=@"weeks ago";
    NSLog(@"I am in week");
} else if ([dateComp day]>0){
    age = [dateComp day];
    ageUnits = @"days ago";
} else if ([dateComp hour]>0){
    age=[dateComp hour];
    ageUnits =@"hrs ago";
}else {
    return @"now";
}

return[NSString stringWithFormat:@"%ld %@", (long)age,ageUnits];

} '''

Doesn't do exactly the same thing, but you should check out the doesRelativeDateFormatting property.
