releasing object after return, is it good practice?

i am just wondering if we can do so:

 SBJsonParser *parser = [[SBJsonParser alloc] init];
    id repr = [parser objectWithString:self];

    return repr;
    [parser release];

So releasing object after returning it, is this a good practice? thanx for any information :)

A method returns to the code that invoked it when it

  • completes all the statements in the method

  • reaches a return statement

  • or throws an exception.

Simple answer: NO

You can not execute anything after a return statement.

Instead you should autorelease the object. That will deallocate it within the next cleanup run of the surrounding AutoreleasePool.

SBJsonParser *parser = [[[SBJsonParser alloc] init] autorelease];
return [parser objectWithString:self];

Have you learned programming basics? After a return statement, nothing is executed.

See: Why does NSLog() not do anything if it's after a method's return?

Actually your code after return statement won't even be executed. glogic's solution is the way to go.

You compiler will not reach the any line after the return statement(Except When you use finally statement.). You got to autorelease it.

SBJsonParser *parser = [[[SBJsonParser alloc] init]]autorealease];//<<< auto release the object on creaion
    id repr = [parser objectWithString:self];
