EXC_BAD_ACCESS当我执行函数的最后一行（webData）时，我得到了一个。

-(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];
}

我尽量不发布任何东西，因为我在网上看到的是它几乎总是一个记忆的东西。

当我调试代码时，(NSZombieEnabled = YES)这是我得到的：

有人有线索吗？

error变量定义有误。你应该使用

NSError *error;

代替

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

然后，当你将它传递给你时，sendSynchronousRequest:returningResponse:error:你应该使用它传递它的地址&error：

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