NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
[sessionConfiguration setAllowsCellularAccess:YES];
[sessionConfiguration setHTTPAdditionalHeaders:#{ #"Accept" : #"application/json" }];
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
NSString *datastring = #"{\"order\": {\"email\": \"foo#example.com\",\"fulfillment_status\": \"fulfilled\",\"send_receipt\":true,\"send_fulfillment_receipt\": true,\"line_items\": [{\"variant_id\": 447654529,\"quantity\": 1}]}}";
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"YOUR LINK"]];
NSLog(#"url=%#",url);
// Configure the Request
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPBody = [datastring dataUsingEncoding:NSUTF8StringEncoding];
request.HTTPMethod = #"POST";
// post the request and handle response
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
// Handle the Response
if(error)
{
NSLog(#"%#",[NSString stringWithFormat:#"Please check your internet connection: %#", [error description]]);
// Update the View
dispatch_async(dispatch_get_main_queue(), ^{
// Hide the Loader
// [MBProgressHUD hideHUDForView:[[UIApplication sharedApplication] delegate].window animated:YES];
[self ShowConnectionError];
});
return;
}
dispatch_async(dispatch_get_main_queue(), ^{
NSString *retVal = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"retVal=%#",retVal);
});
}];
// Initiate the Request
[postDataTask resume];
