Body
copied!<p>You problem is that you are not URLEncoding the data, but feeding it draw into the HTTP body. In this:</p> <pre><code>NSMutableData *body = [NSMutableData data]; NSString *postWerte = @"matr=XXXXX&lang=1&aktkw=1&pressme=S T A R T"; [body appendData:[postWerte dataUsingEncoding:NSUTF8StringEncoding]]; </code></pre> <p>you need to URLEncode "S T A R T", and should bee really URLencoding every string that follows an equal sign. (UPDATE: so it works as is - my service is way picker and I must encode. YMMV!)</p> <p>EDIT: So try changing your code a bit, and if it still fails then please post the first line or two of the returned data:</p> <pre><code>NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil]; assert(returnData); // you should be suppling an error pointer just in case but this will do for now // Log Response { NSString *response = [[NSString alloc] initWithBytes:[returnData bytes] length:[returnData length] encoding:NSASCIIStringEncoding]; NSLog(@"%@",[response substringToIndex:64]); // or a bit mor } NSXMLParser *parser = [[NSXMLParser alloc] initWithData: returnData]; assert(parser); // will be nil if anything has gone wrong, obviously in your real code put an if test [parser setDelegate:self]; // no affect for nil object [parser parse];// no affect for nil object </code></pre> <p>EDIT2:</p> <p>BTW, I missed this, and it may not make a difference, but the parser object has no property "delegate", you technically should be using the setter:</p> <pre><code>[parser setDelegate:self]; </code></pre> <p>Also, you did implement the following, right?</p> <pre><code>parserDidStartDocument: // which I assume you never see, right parser:validationErrorOccurred: parser:parseErrorOccurred: parserDidEndDocument: // you never see this either? </code></pre> <p>If parser is nil, dump the whole returned data as a UTF8 string (per the log code). Also, try looking for an error:</p> <pre><code>dispatch_async(dispatch_get_main_queue(), ^ { NSLog(@"PARSE ERROR: %@", [parser parseError]); } ); </code></pre>
