EXC_BAD_ACCESS NSUrlConnection

Question

У меня есть EXC_BAD_ACCESS, когда я 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 не выпустить вещь, потому что я прочитал в интернете, это почти всегда память вещь.

Когда я отладки кода (NSZombieEnabled = YES) это то, что я получаю:

ли кто-нибудь есть ключ?

Answer 1

В определении переменной error имеется ошибка. 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 с помощью &error:

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