Split up a string

How could I make it so that I can split up a string read from a file into separate strings or make it only read certain line like if i wanted it to only read the first line one the text file and store it into a string. Here is the code i use to read a text file.

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,  NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *pday11 = [documentsDirectory stringByAppendingPathComponent:@"day11.txt"];
    NSString *stringFromFileday11 = [NSString stringWithContentsOfFile:pday11 encoding:NSUTF8StringEncoding error:nil];
//If i used this to read the file how could i split up the "stringFromFileday11" into different strings where every line is a string from the file

Read to a string and split it up

NSString *str = [NSString stringWithContentsOfFile:<YOUR FILEPATH> encoding:NSUTF8StringEncoding error:nil];
NSArray *array = [str componentsSeparatedByString:@"\n"];

(e.g. Read a first line.)

NSString *firstline = [array objectAtIndex:0];
