[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
// Parameter 1
[body appendData:[[NSString stringWithFormat:#"--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Disposition: form-data; name=\"uid\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

// ZIP File Post here
int r = arc4random() % 8000000;
NSString *RandomNumber = [NSString stringWithFormat:#"%d",r];
NSString *file = [RandomNumber stringByAppendingString:#".zip"];

Answer 1

First, there are different styles of web services, and you haven't specified which you're dealing with. Is it a SOAP-based service? REST? XML-RPC? For the sake of discussion, I'll assume it's a RESTful service, since that's where most people seem to be going these days.
The problem I see is that you're trying to put the parameters in the body of the post. You'll have to check the documentation for the specific API that you're using, but usually parameters are provided either as query parameters in the URL that you're posting to, or specified in the headers that you send in the request. The body of the request should be the zipped data.

Try to Send the file your file in this way
NSUInteger length = [myData length];
NSData *filedata;
Byte *byteData = (Byte *)malloc(length);
[data getBytes:byteData length:length];
[postbody appendBytes:(const void *)byteData length:length];
