webservice를 통해 uiimage를 서버에 업로드하는 중 NSXMLParserErrorDomain 오류가 발생합니다.

Question

iPhone에서 웹 서비스에 이미지를 게시하려고합니다.

NSData *Imagedata; 
Imagedata = UIImagePNGRepresentation(imagee); 
strSoapMsg = [[NSString alloc] initWithFormat: 
        @"<?xml version=\"1.0\" encoding=\"utf-8\"?>" 
        "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">" 
        "<soap12:Body>" 
        "<SaveMerchantImageFromIPhone xmlns=\"http://tempuri.org/\">" 
        "<byteArrayImage>%@</byteArrayImage>" 
        "<ProfileID>%d</ProfileID>" 
        "</SaveMerchantImageFromIPhone>" 
        "</soap12:Body>" 
        "</soap12:Envelope>", [NSData dataWithData:Imagedata],merchantProfileID]; 
// strSoapMsg = [[NSString alloc] initWithFormat:@"%@,%d",Imagedata,merchantProfileID]; 
//---print it to the Debugger Console for verification--- 
NSLog(@"soapMsg..........%@",strSoapMsg); 

NSString *str_url = [ NSString stringWithFormat:@"%@user.asmx",xmlWebservicesUrl]; 
NSURL *url = [NSURL URLWithString:str_url]; 
req = [NSMutableURLRequest requestWithURL:url]; 

//---set the headers--- 

NSString *msgLength = [NSString stringWithFormat:@"%d",[strSoapMsg length]]; 
[req addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; 
[req addValue:@"http://tempuri.org/SaveMerchantImageFromIPhone" forHTTPHeaderField:@"SOAPAction"]; 
[req addValue:msgLength forHTTPHeaderField:@"Content-Length"]; 

//---set the HTTP method and body--- 

[req setHTTPMethod:@"POST"]; 
[req setHTTPBody: [strSoapMsg dataUsingEncoding:NSUTF8StringEncoding]]; 


conn = [[NSURLConnection alloc] initWithRequest:req delegate:self]; 
if (conn) 
{ 
    webSaveMerchantImageFromIphone = [[NSMutableData data] retain]; 
} 

나는 %@ 형식 지정자 개체를 필요하기 때문에 실패 생각 : 내가 해봤 모든 것을 설명 먼저 코드를 게시합니다. 그러나 나는 확실하지 않다.

Answer 1

요청이 비동기 적으로 전송되고 응답을 기다리지 않으므로 빈 xml을 파싱하는 중일 수 있습니다.
당신은 당신이받는 데이터와
-(void)connectionDidFinishLoading:(NSURLConnection *)connection 파서을 시작하기를 연결하는 위임 방법
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data를 사용해야합니다.
NSURLConnectionDelegate 프로토콜을 살펴보십시오. https://developer.apple.com/library/mac/#documentation/Foundation/Reference/NSURLConnectionDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intf/NSURLConnectionDelegate

Answer 2

다음은 웹 서비스와 인터페이스하는 방법입니다. 확실히 일을하는 유일한 방법은 아니지만 아마도 가장 인기가 없지만 매우 안전하고 매우 빠릅니다. 첫째로, 나의 웹 서비스는 POST 기반이다. 모든 매개 변수는 크로스 플랫폼 독립성을 제공하는 웹 서비스에 게시됩니다 (PHP와 .NET 기반 웹 서비스 모두 사용함). iOS 앱만 웹 서비스와 통신 할 수 있다는 점에서 보안을 유지하는 모든 웹 서비스 호출과 함께 APIKey를 포함합니다. 또한 APIKey를 변경하고 필요한 경우 사용자가 응용 프로그램의 최신 버전으로 업데이트 할 수있는 기능을 제공합니다 (아직 사용하지 않았지만 사용해야하는 경우에 있습니다.)이 클래스는 AFNetworking에 의존하고 사용합니다. (아이폰 OS 포함 프레임 워크 포함) 네트워크 통신을위한 여러 가지 라이브러리를 사용했으며, AFNetworking을 발견 한 것은 내가 뭐하는 거지에 매우 유용하고 효율적으로 여기

내 클래스의 인터페이스 파일입니다.
