how to remove chat user from roster in other end in open fire xmpp in ios

Question

I have to remove a user issue with open fire xmpp .

1. I Added user_1 in DeviceA it is sending Request to user_2 DeviceB,getting added.

2. When i am removing user_2 from DeviceA, it should remove user_1 in DeviceB but user_1 not removing from DeviceB roster

3. I am not receiving IQ packet subscription="remove"

   I have received IQ packet like subscription="to" and subscription="none"

   How to resolve this Issue?

The above scenario is working as expected in the openfire 3.6 but having problem with 4.1.

Answer 1

I think Openfire 4.1 is behaving correctly according to this defect seen on Openfire 3.6.4 but fixed as of 3.9.2. According to RFC-3921 Section 8.6:

When the user removes the contact from the user's roster, the end state of the contact's roster is that the user is still in the contact's roster with a subscription state of "none"; in order to completely remove the roster item for the user, the contact needs to also send a roster removal request.

To implement what you want, you can explicitly send a remove IQ as discussed here:

• Delete a Friend from Roster in Xmpp/Openfire

And you can refer to the best practice here:
