Reading a Text File line by line and Tokenizing each line in Objective C

Here's a confirmed working code of how to read a file line by line and thereafter, tokenizing it. 

    NSString *path = [[NSBundle mainBundle] pathForResource:@"test2" ofType:@"txt"];

    NSString *string = [[NSString alloc] initWithContentsOfFile:path encoding:NSASCIIStringEncoding error:NULL];

    NSArray *lines = [string componentsSeparatedByString:@"\n"]; // each line, adjust character for line endings

    NSEnumerator *nse = [lines objectEnumerator];

    NSMutableArray *values = [NSMutableArray new];

    NSString *tmp;

    while(tmp = [nse nextObject])

    {

NSArray *chunks = [tmp componentsSeparatedByString: @","];

NSEnumerator *nse2 = [chunks objectEnumerator];

NSString *tmp2;

while(tmp2 = [nse2 nextObject]){

NSLog(@"%@",tmp2);

}

NSLog(@"%@", tmp);

    }
