7th paragraph

The paragraph starts with "mmalcolm Crawford ... ". That should probably be "Malcolm ...".

Ex. 1.9

The code frag shows "title = [newTitle copy]";
shouldn't that be "title = [aTitle copy]"?
At least, there ought to be some declaration for newTitle, no?

11th paragraph

There is a line of code that looks like this:

char cStr = [str UTFString];

when it should be:

char *cStr = [str UTF8String];

The pointer was forgotten, and the method is UTF8String, not UTFString.

NString should be NSString.

2nd paragraph

In the beginning of the example some NSNumber's are instantiated with names
cN,lN,usN. Later the variable names are backwards and loose the capitalization on the N.

The line BOOL b = [nc isEqualToNumber:nl];
should be BOOL b = [cN isEqualToNumber:lN];

Likewise the line NSComparisonResult r = [nc compare:nus];
should be NSComparisonResult r = [cN compare:usN];

also
r = [nus compare:ns];
should be r = [usN compare:cN]; //not sure if cN is what you want here, my guess is yes

Example 2-11, 8th 'paragraph'

set1 is created as (a, b, c, d)
set3 is created as (c, d, e, f)

Fourth line of code is
b = [set3 intersectsSet:set1]; // Returns NO
However, these two sets do intersect, and this code returns YES (tested on Leopard)

//Create a dictionary with many objects and keys

This is wrong:
d = [NSDictionary dictionaryWithObjects:@"a", @"b", nil
forKeys:@"A", @"B", nil];

Should be:
d = [NSDictionary dictionaryWithObjects: [NSArray arrayWithObjects: @"a", @"b", nil]
forKeys:[NSArray arrayWithObjects:@"A", @"B", nil]];

The bottow figures in brackets might also need correcting to: (50, 25), phase = 25

incorrect... shouldthese not read (respectively):

In example 6.1, under the comment "Other ways to create a host object"

The examples using hostWithAddress: and hostWithName: need to be switched, i.e. it
should read hostWithName:@"www.oreilly.com"

Ex. 6-2

The third example showing how to initialize with scheme, host and path,
has an extra space in the string for the scheme. It should read (in
part):
initWithScheme:@"FTP"

Typo: "NSAtrributedString" should be "NSAttributedString".

Also, extra word "strin".

-(void)curveToPoint:(NSPoint)endPoint;

controlPoint1:(NSPoint)controlPoint1
controlPoint2:(NSPoint)controlPoint2;
