xmpp ios 註冊 添加好友

註冊很簡單的：如下
在appdelegate裡面定義一個方法如下
- (BOOL)registeriTalk:(NSString *)un pwd:(NSString *)pwd
{
    isLoginOperation = NO;
    self.userName = un;
    self.password = pwd;
   
    return [self connect];
}
isLoginOperation判斷是登陸還是註冊，註冊之前必須調用 [self connect]；
在這個代理方法中調用xmpp提供的註冊方法
- (void)xmppStreamDidConnect:(XMPPStream *)sender
{
        DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
       
        isXmppConnected = YES;
       
        NSError *error = nil;
    if (isLoginOperation) {
        [[self xmppStream] authenticateWithPassword:password error:&error];
    }else
    {
        if (![[self xmppStream]registerWithPassword:password error:&error]) {
            DDLogError(@"Error register", error);
        }
    }
}
就可以實現註冊了

添加好友很簡單的啊 xmpp提供方法了啊
