EXC_BAD_ACCESS NSUrlConnection

1 голос
/ 31 мая 2010

Я получил EXC_BAD_ACCESS, когда выполняю последнюю строку функции (webData). 

-(void)requestSoap{
NSString *requestUrl = @"http://www.website.com/webservice.php";
NSString *soapMessage = @"the soap message";
//website and soapmessage are valid in original code.

 NSError **error;
 NSURLResponse *response;

 //Convert parameter string to url
 NSURL *url = [NSURL URLWithString:requestUrl];
 NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10];

 NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];

 //Create an XML message for webservice
 [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
 [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
 [theRequest setHTTPMethod:@"POST"];
 [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

 NSData *webData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&response error:error];
}

Я пытался ничего не выпускать, потому что я читаю в сети, что это почти всегда память.

Когда я отлаживаю код (NSZombieEnabled = YES), я получаю следующее:

У кого-нибудь есть подсказка?

Ошибка определения переменной error. Вы должны использовать 

NSError *error;

вместо 

NSError **error; // There is a '*' too much here

Затем, когда вы передаете его sendSynchronousRequest:returningResponse:error:, вы должны передать его адрес, используя &error: 

[NSURLConnection sendSynchronousRequest:theRequest
                      returningResponse:&response
                                  error:&error];
...
