XMPPFramework - Which XMPPRoster function to use to send a friend request?

I am trying to implement an Instant Messaging App where users can chat as well as add other users to their roster and accept buddy requests. So, far I have been able to implement the chat and I am also able to receive and accept/reject friend requests.

For accepting/rejecting a subscription request, the code is as follows:

- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence
{
    NSString *presenceType = [presence type]; // online / offline
    NSString *myUsername = [[sender myJID] user];
    NSString *presenceFromUser = [[presence from] user];
    NSString *presencefromStr=[presence fromStr];

    if  ([presenceType isEqualToString:@"subscribe"]) {
        if(buttonIndex==1) { // For accept button
            [xmppRoster acceptPresenceSubscriptionRequestFrom:[tmpPresence from] andAddToRoster:YES];
    }
    else { // For reject button
        [xmppRoster rejectPresenceSubscriptionRequestFrom:[tmpPresence from]];
    }
}

However, now I am stuck with the problem of not being able to send a friend request. Can anyone guide me on which function of XMPPRoster to use? I tried using the subscribePresenceToUser function, but, it didn't work. Any help will be highly appreciated.

Also, can someone tell if the way I am going with this XMPPRoster subscription mechanism is right or is there a better way to handle the friend requests in XMPPFramework?

Thanks in advance.

You can see XMPPRoster.h to see all the functions available inside the roster extension.

For your answer you have three options:

/**
 * Adds the given user to the roster with an optional nickname 
 * and requests permission to receive presence information from them.
**/
- (void)addUser:(XMPPJID *)jid withNickname:(nullable NSString *)optionalName;

/**
 * Adds the given user to the roster with an optional nickname, 
 * adds the given user to groups
 * and requests permission to receive presence information from them.
**/
- (void)addUser:(XMPPJID *)jid withNickname:(nullable NSString *)optionalName groups:(nullable NSArray<NSString*> *)groups;

/**
 * Adds the given user to the roster with an optional nickname,
 * adds the given user to groups
 * and optionally requests permission to receive presence information from them.
**/
- (void)addUser:(XMPPJID *)jid withNickname:(nullable NSString *)optionalName groups:(nullable NSArray<NSString*> *)groups subscribeToPresence:(BOOL)subscribe;

And to accept the friend request : (add as friend, as Fan or Decline)

addToRoster flag = true : Friend

addToRoster flag = false : Fan

/**
 * Accepts the presence subscription request the given user.
 * 
 * If you also choose, you can add the user to your roster.
 * Doing so is similar to the traditional IM model.
**/
- (void)acceptPresenceSubscriptionRequestFrom:(XMPPJID *)jid andAddToRoster:(BOOL)flag;

/**
 * Rejects the presence subscription request from the given user.
 * 
 * If you are already subscribed to the given user's presence,
 * rejecting they subscription request will not affect your subscription to their presence.
**/
- (void)rejectPresenceSubscriptionRequestFrom:(XMPPJID *)jid;

Answer by OP in comment:

XMPPJID *jid = [XMPPJID jidWithString:self.addFriendField.text];
[xmppRoster addUser:jid withNickname:nil];

This code snippet sends the request to other users and adds them to their Roster.
