使用XMPP框架创建登录和注册

Question

我正在尝试制作一个XMPP登录和一个注册页面，它们彼此分离，服务器是基于明火的。此外，我没有使用入站注册。我想强调的是，这是我第一次尝试这样做，我以前的经验只涉及使用NSSession进行注册/登录。我想说的是，我购买并阅读了Peter van de Put撰写的《掌握XMPP框架》一书，但他只解释了如何进行入站注册/登录。还有我遇到的其他链接：1-他们之间的答案相似

2-教程

PS：我注册时需要发送到服务器的信息是：创建时的电子邮件、姓名和密码当我登录时：电子邮件，密码

为iOS构建Jabber客户端在本教程中，我不明白登录是如何进行的，因为它只将用户凭据保存在NSUserDefaults中。

您可以下载我在这里实现的内容（使用stackoverflow建议）：到目前为止我的代码和数据库结构图片

更新，这是我试图用于注册的代码：

->.h文件：

#import <UIKit/UIKit.h>
#import <CoreData/CoreData.h>
#import "XMPP.h"
#import "XMPPRoster.h"
@interface SignUpViewController : UIViewController <UITextFieldDelegate, UIApplicationDelegate, XMPPRosterDelegate, XMPPStreamDelegate>
{
    XMPPStream *xmppStream;
}
@property (nonatomic, strong, readonly) XMPPStream *xmppStream;
@end

->.m文件

- (void)signUpButtonFunction{
    NSLog(@"SignUp function");
    [[self xmppStream] setHostName:@"IP_ADDRESS"];
    [[self xmppStream] setHostPort:5222];
    XMPPJID *jid=[XMPPJID jidWithString:emailTextField.text];
    [[self xmppStream] setMyJID:jid];
    [[self xmppStream] connectWithTimeout:3.0 error:nil];
    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:@"email" stringValue:@"[e-mail]"]];
    [ xmppStream registerWithElements:elements error:nil];
}

//server connect delegate methods are not working at least it doesn't enter in them
- (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];
}

所以，在搜索此事后，我发现在openFire上可以安装一个允许正常注册的插件，所以我实现了下一个注册方法：

NSString *urlToCall = @"http://MyIP:9090/plugins/userService/userservice?type=add&secret=BigSecretKey&username=testUser&password=testPass&name=testName&email=[e-mail]";
NSURL *url = [NSURL URLWithString:urlToCall];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
[theRequest setHTTPMethod:@"GET"];
NSError *error = nil;
NSURLResponse *response;
NSData *result = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&response error:&error];
NSString *responseString = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];
if ([responseString  isEqual: @"<result>ok</result>rn"]) {
    NSLog(@"user created");
} else {
   NSLog( @"user NOT created");
    NSLog(@"%@",responseString);
}
