streamreader

I am trying to remake a program I have made in C# in OBJ-C.In C# I used streamreader to search the data file for the line I am looking for then convert that line into a string that I can work with.

I have looked at NSScanner but I'm not sure if thats quite waht I'm looking for but I'm by no means a cocoa expert.

All I would like to be able to do is have it search a data file for an occurance of a string, then when/if it finds an occurance of that string, it returns the line that string was found on as a string.

Any ideas?
