In this case, you're returning an autoreleased instance, so no
worries. The Memory Management Guide explains this in detail. If you
retain something and you don't release it, you'll end up with a
memory leak. It won't be released automatically.

and another question :)
if i retain an object when entering a function and i do not release
it, will it be released automatically?
after the function ends ?
in the example of this structure of function.
+ (NSNumber *)xxxxxNumber: (NSString *) input{
return [NSNumber numberWithInt: [encode uncodeInteger:input]];
}
There is really no space for me to release it before the return ...
Thank you

Oh and would it be absolutely wise for me to retain the input
value just in case
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.
