Re make multiple line to paragraph in objective c

i have this 2 paragraphs like this

On Friday afternoon after you leave work, you probably
think about going out and having a few drinks with 
friends to relax and wind down.  Even though you 
may think you deserve to go out and have a few drinks,
there are some things that you should certainly keep
in mind.

Like any other day, tomorrow is going to be a day
for exercise, and since you are exercising on a 
regular basis, a few drinks of alcohol won't really
hurt anything, right?  Before you decide to rush out
to the local bar, there are a few things below that
you should think about before you make your choice
about going out to drink some alcohol.

How can i format to this:

I only know how to replace \n with space like this:

stringByReplacingOccurrencesOfString:@"\n" withString:@" "

But i dont know how to recognize each paragraph

Thanks you

This code isn't bulletproof and additional code is needed to clean up any extraneous newline characters, but it should serve to start you off:

// Assuming your input string contains all the text, then:

NSArray *paragraphs = [input componentsSeparatedByString:@"\n\n"];
for (NSString *paragraph in paragraphs)
{
    NSString *cleaned = [paragraph stringByReplacingOccurrencesOfString:@"\n" withString:@" "];
    NSLog(@"paragraph = %@", cleaned);
}

Search for two consecutive "\n\n". This will tell you it's a paragraph.
