How to return nothing from a method with return type of id

Question

I have the following method:

- (id) insertDictationResultPlaceholder
{
    return nil;
}

The Xcode analyzer is barking at me and telling me:

nil returned from a method that is expected to return a non-null value

So, for a method with a return parameter of id, how do I return nothing? Would an empty string be good? What's the nicest solution here?

Answer 1

You can use [NSNull null] instead. Just be cautious when you're checking for it, because it does NOT equate to nil if you try to do a comparison:

if ([NSNull null] == nil)
{
    // This code will never run
}
