ios - xmpp框架iOS新用户注册方法

Question

我已经为 iOS 开发了 XMPP 聊天客户端，现在我正在研究如何从 iOS 本身进行新用户注册。任何人都可以帮助注册新用户的方法。因为它需要与服务器通信并将用户名和密码存储到服务器数据库中。请帮助我从 2 天开始搜索它。

Answer 1

NSMutableArray *elements = [NSMutableArray array];
[elements addObject:[NSXMLElement elementWithName:@"username" stringValue:@"venkat"]];
[elements addObject:[NSXMLElement elementWithName:@"password" stringValue:@"dfds"]];
[elements addObject:[NSXMLElement elementWithName:@"name" stringValue:@"eref defg"]];
[elements addObject:[NSXMLElement elementWithName:@"accountType" stringValue:@"3"]];
[elements addObject:[NSXMLElement elementWithName:@"deviceToken" stringValue:@"adfg3455bhjdfsdfhhaqjdsjd635n"]];

[elements addObject:[NSXMLElement elementWithName:@"email" stringValue:@"abc@bbc.com"]];

[[[self appDelegate] xmppStream] registerWithElements:elements error:nil];

我们将使用以下代理知道注册是否成功。

- (void)xmppStreamDidRegister:(XMPPStream *)sender{


    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Registration" message:@"Registration Successful!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
}


- (void)xmppStream:(XMPPStream *)sender didNotRegister:(NSXMLElement *)error{

    DDXMLElement *errorXML = [error elementForName:@"error"];
    NSString *errorCode  = [[errorXML attributeForName:@"code"] stringValue];   

    NSString *regError = [NSString stringWithFormat:@"ERROR :- %@",error.description];

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Registration Failed!" message:regError delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];

    if([errorCode isEqualToString:@"409"]){        

        [alert setMessage:@"Username Already Exists!"]; 
    }   
    [alert show];
}
