试试这个 -

NSString *urlString = [ NSString stringWithFormat:@"http://domine.com/as/web_services/change_user_image?user_id=%@",self.useridString];
        NSData *imageData = UIImageJPEGRepresentation(theImage, 0.5);
        NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:urlString]];
        request.timeoutInterval = 10.0f;
        request.HTTPMethod = @"POST";

        NSString *boundary = @"011000010111000001101001";
        NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary, nil];
        [request addValue:contentType forHTTPHeaderField:@"Content-Type"];


        NSMutableData *body = [NSMutableData data];



        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

        [body appendData:[[NSString stringWithFormat:@"Content-Disposition:form-data; name=\"projectId\"\r\n\r\n"]dataUsingEncoding:NSUTF8StringEncoding]];
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

        NSData *stringData = [@"Content-Disposition: form-data;\
                              name=\"project\";\
                              fileName=\"photo.jpeg\"\r\n"
                              dataUsingEncoding:NSUTF8StringEncoding];
        [body appendData:stringData];
        [body appendData:[@"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
        [body appendData:imageData];

        [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
        [request setHTTPBody:body];
        NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
        NSString *returnString = [[NSString alloc] initWithData:returnData encoding
