Question

I am new to Objective C, so I’m not really even sure what this message means:

EXC_BAD_ACCESS

When executing the following code:

-(void)HelloWorld
{
    NSURL *url = [NSURL URLWithString:@"http://example.com/service.asmx/HelloWorld"];
    NSMutableURLRequest *request =[NSMutableURLRequest requestWithURL: url];

    //do post request for parameter passing 
    [request setHTTPMethod:@"POST"];

    //set the content type to JSON
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

    NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
    [connection release];
    [request release];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data 
{
    // Store incoming data into a string
    NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
}

I’m attempting to integrate with the Json Framework.

I call HelloWorld, which executes an async request to my service. What’s strange, is that it worked one time, and now I get this EXC_BAD_ACCESS message every subsequent time. Any ideas what would be causing this?

You shouldn’t be releasing the request. It’s already autoreleased.
