Answer 1

In order to transmit an image captured with the camera to CamFind API using Unirest, you need to same the image first.

// Get the path to the Documents folder
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectoryPath = [paths objectAtIndex:0];

// Get the path to an file named "tmp_image.jpg" in the Documents folder
NSString *imagePath = [documentDirectoryPath stringByAppendingPathComponent:@"tmp_image.jpg"];
NSURL *imageURL = [NSURL fileURLWithPath:imagePath];

// Write the image to an file called "tmp_image.jpg" in the Documents folder
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
[imageData writeToURL:imageURL atomically:YES];

// Now construct the parameters that will be passed to Unirest
NSDictionary* parameters = [NSDictionary dictionaryWithObjectsAndKeys:@"en_US", @"image_request[locale]", @"en", @"image_request[language]", imageURL, @"image_request[image]", nil];

// And the headers
NSDictionary* headers = [NSDictionary dictionaryWithObjectsAndKeys:@"<mashape-key>", @"X-Mashape-Authorization", nil];

// Call the API using Unirest
HttpJsonResponse* response = [[Unirest post:^(BodyRequest* request) {
    [request setUrl:@"https://camfind.p.mashape.com/image_requests"];
    [request setHeaders:headers];
    [request setParameters:parameters];
}] asJson];
