登录到网站在iphone

Question

i am developing one app which will login to vonage website and do some functions like call froward etc . For that purpose first i am trying to login to vonage website 

我没有

https://secure.vonage.com/vonage-web/public/login.htm

2）使用livehttpheader附加实测值Vonage公司的登录URL这些步骤

1）来捕获呼出交请求数据，当我点击sigin

我发现的数据是

用户名=名为myUsername &密码=输入mypassword & redirectingURL =％2Fwebaccount％2Fdashboard％2Fchoose.htm & frontDoorLogin = & goToSelection =来电转驳& loginsubmit等号（=）+在

我得到了我的资料后，我开始在xcode编码，我不知道什么是最好的办法做到这一点，但我搜索了一段时间，然后我试着这样

-(IBAction) buttonpressed { 

    NSURL *url = [NSURL URLWithString:@"https://secure.vonage.com/vonage-web/public/login.htm"]; 

    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; 
    [request setValue:@"myuser" forKey:@"username"]; 
    [request setValue:@"mypass" forKey:@"password"]; 
    [request setValue:@"/webaccount/dashboard/choose.htm" forKey:@"redirectingURL"]; 
    [request setValue:@"" forKey:@"frontDoorLogin"]; 
    [request setValue:@"callforwarding" forKey:@"goToSelection"]; 
    [request setValue:@"Sign+In" forKey:@"loginsubmit"]; 
    [request setDelegate:self]; 
    [request startAsynchronous]; 



} 

- (void)requestFinished:(ASIFormDataRequest *)request 
{ 
    // Use when fetching text data 
    NSString *responseString = [request responseString]; 

    UIAlertView *alert= [[UIAlertView alloc] initWithTitle:@"Hmm" message:@"http works" delegate:self cancelButtonTitle:@"okay" otherButtonTitles:nil]; 

    [alert show]; 
    [alert release]; 
    NSLog(@"Output = %@",responseString); 

} 

- (void)requestFailed:(ASIFormDataRequest *)request 
{ 
    NSError *error = [request error]; 
    UIAlertView *alert= [[UIAlertView alloc] initWithTitle:@"fail" message:@"http fails" delegate:self cancelButtonTitle:@"okay" otherButtonTitles:nil]; 

    [alert show]; 
    [alert release]; 
} 

但是当我在模拟器中运行应用程序时，它崩溃了。

我在做数据发布的正确方法吗？有没有其他方法可以做到这一点？

任何一个可以帮助我在这个问题上

我使用asihttprequest库

在此先感谢

问候

编辑：我盲目的错误，我种SETVALUE代替setpostvalue，这将解决这个问题:)

Answer 1

看节题为Sending a form POST with ASIFormDataRequest

// using post value 
[request setPostValue:@"myuser" forKey:@"first_name"]; 

还我通常做我的警示与自动释放，不知道这是你的问题，但你可能想尝试的改变也

UIAlertView *alert= [[[UIAlertView alloc] initWithTitle:@"Hmm" message:@"http works" 
     delegate:self cancelButtonTitle:@"okay" otherButtonTitles:nil] autorelease]; 

    [alert show]; 

UIAlertView中代表代码

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex: 
                (NSInteger)buttonIndex { 
     // do your thing 
    }
