Objective-C and autorelease on return

Are the two me开发者_开发问答thods

- (id) myFirstMethod
{
  NSObject* anObject = [[NSObject alloc] init];
  [anObject autorelease];
  return anObject;
}

- (id) mySecondMethod
{
  NSObject* anObject = [[NSObject alloc] init];
  return [anObject autorelease];
}

identical?

Yes the both methods are identical. Whenever you write a nested function or same code in multiple lines, it is all the same after compilation.

You could do everything in the return:

- (id) myThirdMethod {
    return [[[NSObject alloc]init]autorelease];
    }

Yes they are identical, but all they do is to cause a compiler error.

[anObject] is not allowed. And NSObject anObject is also invalid syntax.
