Question

I have an object with the following members:

NSString *reqStr = "param1=val1&param2=val2&param3=val3&..";
NSData *imageData = [NSJPEGRepresentation (myimage)];
NSData *fileContents = [NSData initWithFileContents(myfile.txt)];

How can I send this out to Windows WCF? Do I send it as stream of bytes, and attach to httprequest? Or, will this be sockets? I am not sure how to pack these things as one thing as in one stream of bytes or whatever it may be the way to format such an object.

Any help?

Since you said that you already know how to send imageData which is NSData. Why not convert regStr to NSData and combine all three together as a single data and send.

To convert NSString to NSData:

NSData* strData=[regStr dataUsingEncoding:NSUTF8StringEncoding];

And use NSMutableData‘s appendData method to combine all three.

NSMutableData *combineData = [[NSMutableData alloc]initWithData:strData];
[combineData appendData:imageData];
[combineData appendData:fileData];
