If you don't want to do anything fancy with the file but store those text objects, how about putting them into an NSArray and using NSArchive/NSUnarchive to write/read them?
NSArray *someArray = [ NSArray arrayWithObjects:text,fields,here,nil ];
if( [ NSArchiver archiveRootObject:someArray
toFile:@"/tmp/archfile" ] == YES )
// do something when successful here
// do something when fails here
NSArray *readArray = [ NSUnarchiver unarchiveObjectWithFile:@"/tmp/archfile" ];
// then just [ readArray objectAtIndex:0 ]
// and :1 :2 etc...
