Creating a folder that already exists (iOS)

[Robert S.138]

I went through this already for Android, and I learned that to create a folder that might already exists I only need to check the exception as follows:

catch (CreateFolderErrorException err) {
if( ! (err.errorValue.isPath() && err.errorValue.getPathValue().isConflict()) )
{ /* a real error, to be handled */ }
else  {/*this exception can safely be ignored*/}

Now I need to do the same thing in the Objective-C SDK for iOS.  In the completion block for createFolder I get:

^(DBFILESFolderMetadata *result, DBFILESCreateFolderError *cfError, DBError *error)

What is the equivalent check using "result", "cfError", and "error"?

That fixed it.  Now just one import replaces all the other Dropbox imports I was using.
