Here’s an example to upload an image (or any data file) to a server:

- (void) uploadMediaForUserId: (NSString*) userId {
	NSMutableDictionary *parameters = [NSMutableDictionary dictionaryWithObjectsAndKeys:
								kAPIVersion, @"v",
								nil];
	// Media Name
	if( TTIsStringWithAnyText(_mediaName)){
		[parameters setObject:_mediaName forKey:@"n"];
	}

	// Media Description
	if( TTIsStringWithAnyText(_mediaDescription)){
		[parameters setObject:_mediaDescription forKey:@"d"];
	}

	// REST resource, where kMedia: @"/users/%@/media";
	NSString *resource = [NSString stringWithFormat:kMedia, userId];

	// Create the URL, where kServerURL is something like "http://www.dougdiego.com"
	NSString *url = [kServerURL stringByAppendingFormat:@"%@?%@", resource, [parameters gtm_httpArgumentsString]];
	// Resulting URL looks like: http://www.dougdiego.com/users/12345/media

	TTURLRequest* request = [TTURLRequest requestWithURL:url  delegate:self];
	request.httpMethod = @"POST"; 

	NSString * imageLocalUrl = [NSString stringWithFormat:@"documents://%@",_mediaFilename];
	NSData *imageData = UIImageJPEGRepresentation(TTIMAGE(imageLocalUrl), 0.6); 

	// Set the media file with the parameter: file
	[request addFile:imageData mimeType:@"image/jpeg"  fileName:@"file"]; 

	request.cachePolicy = TTURLRequestCachePolicyNoCache;
	request.cacheExpirationAge = TT_CACHE_EXPIRATION_AGE_NEVER;

	TTURLJSONResponse* response = [[TTURLJSONResponse alloc] init];
	request.response = response;
	TT_RELEASE_SAFELY(response);

	[request send];
}
