Good point,
i'll keep it in mind...
just a quick question, if i'm retaining an object from a thread and
the thread is released while
i'm accessing/working with the object will the thread wait until i'm
finished or will it be released, and the object live until i'm
finished with it ?

As a note of completeness, it's not something you typically need to
worry about when dealing with values passed in from the same
thread. However, if your application is multithreaded, and the
method will be dealing with input values from threads outside of
the method's scope, it may be wise to retain the input values for
the life of the method.

No. You don't own the input value, so it's not your responsibility.

Oh and would it be absolutely wise for me to retain the input

it is already auto-released somewhere else? and release it before
the function ends?

Greetings,
i was just wondering if Cocoa behaved like other languages
concerning variable scope.
i did search the documentation for variable scope but all i get
back is the references for Apple Scripts ...
so... in this function.
+ (NSString *)numberFizzle: (NSNumber *) input{
NSString *intToStr = [ [ [NSString alloc] stringWithFormat:@"%
d",[input intValue]] autorelease];
NSString *tempStr = [ [ [NSString alloc] stringWithFormat:@"i%d:
%d", [intToStr length], [input intValue]] autorelease];
NSLog(tempStr);
return tempStr;
}
so if Objective-C (cocoa) behaves like i think. there is no need
for me to autorealease anything that does not exit my function.
so fo example here, the intToStr variable will be automatically
killed at the end of the function
so i would not have to autorelease it... BUT tempStr will exit
the function therefor i should autorelease it just in case it is
not released by the user...
is that right ?
Thank you for your assistance !
Sandro Noel.
