hey... i've noticed you're reading cocoa programming (3rd)... not sure if know already, there solutions on website (bignerdranch.com) can download , compare own code if you're having problems (although of solutions not written in book)... being said, still think practice write code out following book can use of syntax, etc..

also, should use "[ code ]" "[ /code ]" tags when post code on board... makes easier read...
