Get request as soon token received - ios

Question

I'm using the camfind api, I post a request where I send the api an image and get a token, and then I can use the token to get what the image is, but this takes two steps, a post and a get request. I want to combine them, so the get request auto fires right when the server responds to the post request. Here is the code :
I specify a value for the token at the top
NSString *tokenValue;
the request method, here an image is selected and sent to the server, the server sends a token response back in this request
- (void *) requestMethod: (UIImage *)imageToConvert{
NSString *temp = #"saved";
NSLog(#"%#", temp);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectoryPath = [paths objectAtIndex:0];
NSString *imagePath = [documentDirectoryPath stringByAppendingPathComponent:#"tmp_image.jpg"];
NSURL *imageURL = [NSURL fileURLWithPath:imagePath];
NSData *imageData = UIImageJPEGRepresentation(imageToConvert , 1.0);
[imageData writeToURL:imageURL atomically:YES];
// NSString *base64image = [NSString stringWithFormat:#"%#",[imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength]];
NSString *base64image = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
// These code snippets use an open-source library.
// NSString *baseboy = [base64image stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
// NSURL *urlimage_request = [NSURL URLWithString:[base64image stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSDictionary *headers = #{#"X-Mashape-Key": #"********"};
NSDictionary *parameters = #{#"focus[x]": #"480", #"focus[y]": #"640", #"image_request[altitude]": #"27.912109375", #"image_request[image]": imageURL, #"image_request[language]": #"en", #"image_request[latitude]": #"35.8714220766008", #"image_request[locale]": #"en_US", #"image_request[longitude]": #"14.3583203002251"};
UNIUrlConnection *asyncConnection = [[UNIRest post:^(UNISimpleRequest *request) {
[request setUrl:#"https://camfind.p.mashape.com/image_requests"];
[request setHeaders:headers];
[request setParameters:parameters];
}] asJsonAsync:^(UNIHTTPJsonResponse *response, NSError *error) {
NSInteger code = response.code;
NSDictionary *responseHeaders = response.headers;
UNIJsonNode *body = response.body;
NSData *rawBody = response.rawBody;
NSString *token = response.description;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:response.rawBody
options:kNilOptions
error:nil];
NSLog(#"Response status: %ld\n%#", (long) response.code, json);
for(NSString *key in [json allValues])
{
tokenValue = [json valueForKey: #"token" ];
NSString *two = [json valueForKey: #"token" ]; // assuming the value is indeed a string
NSLog(#"Token :%#", two);
NSString *one = #"https://camfind.p.mashape.com/image_responses" ;
NSDictionary *headers = #{#"X-Mashape-Key": #"9hcyYCUJEsmsh4lNTgpgVX1xRq0Ip1uogovjsn5Mte0ONVBtes", #"Accept": #"application/json"};
NSString *responseString = [NSString stringWithFormat:#"%#/%#", one, two];
// NSString *responseURL = [one stringByAppendingString:two];
NSLog(#"response URL %#", responseString);
// UNIUrlConnection *asyncConnection = [[UNIRest get:^(UNISimpleRequest *request) {
// [request setUrl:responseString];
// [request setHeaders:headers];
// }] asJsonAsync:^(UNIHTTPJsonResponse *response, NSError *error) {
// NSInteger code = response.code;
// NSDictionary *responseHeaders = response.headers;
// UNIJsonNode *body = response.body;
// NSData *rawBody = response.rawBody;
// NSDictionary *json = [NSJSONSerialization JSONObjectWithData:response.rawBody
// options:kNilOptions
// error:nil];
// NSLog(#"Response status: %ld\n%#", (long) response.code, json);
//
//
// // NSLog(#"didfinishLoadingbody%#",rawBody);
// // NSLog(#"didfinishLoadingbody%#",body);
// //
// // NSLog(#"didfinishLoading responseheader%#",responseHeaders);
// // NSLog(#"didfinishLoading tok%#",token);
// }];
}
// NSLog(#"didfinishLoadingbody%#",rawBody);
// NSLog(#"didfinishLoadingbody%#",body);
//
// NSLog(#"didfinishLoading responseheader%#",responseHeaders);
// NSLog(#"didfinishLoading tok%#",token);
}];
return (__bridge void *)(self);
}
the response method below uses the token from the request above to print out what the image is
- (void *) responseMethod {
// These code snippets use an open-source library.
NSString *one = #"https://camfind.p.mashape.com/image_responses" ;
NSString *responseString = [NSString stringWithFormat:#"%#/%#", one, tokenValue];
NSDictionary *headers = #{#"X-Mashape-Key": #"9hcyYCUJEsmsh4lNTgpgVX1xRq0Ip1uogovjsn5Mte0ONVBtes", #"Accept": #"application/json"};
UNIUrlConnection *asyncConnection = [[UNIRest get:^(UNISimpleRequest *request) {
[request setUrl:responseString];
[request setHeaders:headers];
}] asJsonAsync:^(UNIHTTPJsonResponse *response, NSError *error) {
NSInteger code = response.code;
NSDictionary *responseHeaders = response.headers;
UNIJsonNode *body = response.body;
NSData *rawBody = response.rawBody;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:response.rawBody
options:kNilOptions
error:nil];
NSLog(#"Response status: %ld\n%#", (long) response.code, json);
// NSLog(#"didfinishLoadingbody%#",rawBody);
// NSLog(#"didfinishLoadingbody%#",body);
//
NSLog(#"didfinishLoading responseheader%#",responseHeaders);
// NSLog(#"didfinishLoading tok%#",token);
}];
return (__bridge void *)(self);
}
rest of the vc other stuff
-(void)loadView {
[super loadView];
}
- (void)viewDidLoad{
[super viewDidLoad];
}
-(void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
}
-(void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
-(void)viewWillDisappear:(BOOL)animated{
[super viewWillDisappear:animated];
}
I don't know how to make the response method fire right away when the server replies, I don't know objc, im using this in a swift project
