Hi,


Thanks for your timely article on AppleScript and Cocoa. I found your article very informative and enjoyable.


Just a minor point. Your setter example causes some problems such as memory leak. Your code


mystring = str;


should've been


[mystring autorelease]; or [mystring release];
mystring = [str copy]; or mystring = [str retain];


Thanks again for your article. I'm looking forward to reading your next one.

    Hi Shin,

    You are quite correct that one of your suggested means of releasing the existing mystring should have been used when making the new assignment to avoid memory leaks. I can only claim that I was trying to use the minimum amount of code to keep all of the concepts clear and I didn't want to introduce the issues concerning memory management and Objective-C. But, for completeness you are absolute correct and I will add this to future examples.

    Brad
