这是我用来发送好友请求的代码，工作正常

XMPPJID *newBuddy = [XMPPJID jidWithString:userName];
[[self appDelegate].xmppRoster addUser:newBuddy withNickname:nil];

这是我用来接受好友请求的代码，工作正常。

XMPPJID *newBuddy = [XMPPJID jidWithString:ipAddress];
     [[self appDelegate].xmppRoster acceptPresenceSubscriptionRequestFrom:newBuddy andAddToRoster:YES];

问题是，每当再次接受请求时，我都会从接受的用户那里获得订阅，这就是问题所在。如何在 xmpp 中停止双向订阅帮助我

最后，我通过使用用户名和所有用户搜索用户找到了替代答案。

1.对于每个带有 gmail id 的联系人 user@gmail.com

2.对于具有特定名称的特定用户，请使用 userName。

3.要从开火服务器获取所有用户，只需在搜索字符串中输入“*”。

//Request
- (void)getDetailsofRegisteredUser {

    //To Search Peticular User either by using their name, email or username
    NSString *userBare1  = [[[[self appDelegate] xmppStream] myJID] bare];
    NSXMLElement *query = [NSXMLElement elementWithName:@"query"];
    [query addAttributeWithName:@"xmlns" stringValue:@"jabber:iq:search"];

    NSXMLElement *x = [NSXMLElement elementWithName:@"x" xmlns:@"jabber:x:data"];
    [x addAttributeWithName:@"type" stringValue:@"submit"];

    NSXMLElement *formType = [NSXMLElement elementWithName:@"field"];
    [formType addAttributeWithName:@"type" stringValue:@"hidden"];
    [formType addAttributeWithName:@"var" stringValue:@"FORM_TYPE"];
    [formType addChild:[NSXMLElement elementWithName:@"value" stringValue:@"jabber:iq:search" ]];

    NSXMLElement *userName = [NSXMLElement elementWithName:@"field"];
    [userName addAttributeWithName:@"var" stringValue:@"Username"];
    [userName addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1" ]];


- (void)getDetailsofRegisteredUser {

    //To Search Peticular User either by using their name, email or username
    NSString *userBare1  = [[[[self appDelegate] xmppStream] myJID] bare];
    NSXMLElement *query = [NSXMLElement elementWithName:@"query"];
    [query addAttributeWithName:@"xmlns" stringValue:@"jabber:iq:search"];

    NSXMLElement *x = [NSXMLElement elementWithName:@"x" xmlns:@"jabber:x:data"];
    [x addAttributeWithName:@"type" stringValue:@"submit"];

    NSXMLElement *formType = [NSXMLElement elementWithName:@"field"];

    [formType addAttributeWithName:@"var" stringValue:@"FORM_TYPE"];
    [formType addChild:[NSXMLElement elementWithName:@"value" stringValue:@"jabber:iq:search" ]];

    NSXMLElement *userName = [NSXMLElement elementWithName:@"field"];
    [userName addAttributeWithName:@"var" stringValue:@"Username"];
    [userName addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1" ]];

    NSXMLElement *name = [NSXMLElement elementWithName:@"field"];

    [search addAttributeWithName:@"var" stringValue:@"search"];
    [search addChild:[NSXMLElement elementWithName:@"value" stringValue:[NSString stringWithFormat:@"%@", SearchString]]];
