ios - Dealing with unexpected response content types with AFNetworking / AFHTTPRequestOperation -


I am using AFNetworking to process HTTP requests in my iOS app. I went into a stumbling I can not be sure what the reaction content will be like, but before processing it will have to set up the response serializer. This means that I can request an API, I can expect an image, but there is actually some authentication error, so the server instead returns a JSON-formatted response.

Here is my code: 

  AFHTTPRequestOperation * op = [[AFHTTPRequestOperation alloc] initWithRequest: request]; [OPP Set Response Laser: [AFJSNRPpsCensializer Serializer]]; // ??? [op setcompletionBlockWithSuccess: ^ (AFHTTPRequestOperation * Operations, ID response object) {NSDictionary * Result = (NSDictionary *) responseObject; OnSuccess ((NSArray *) results); } Failure: ^ (FHttpOrQuest Operation * Operation, NSERR * Error) {Onfiler (Error); }]; [Op start];   
 As you can see, I had to set the expected content type contained by setting up the responsiveness serializer to [AFJSONRPSPenceSyriaLizer Serializer]. So if I get something else, then this causes an error, even though I still want to parse a process that responds when reacting with error.  
 So my question is, should I just use the standard AFHTTPResponseSerializer, check the response status code and then manually process the reaction body (as json, xml, html image etc.)?   
 
 
 On the serializer, you want to set the approved content types:  
 < code> FGSNransponseSerialiser * Serializer = [AFJSONRPSPenceSyriaLizer Serializer]; Serializer.acceptableContentTypes = [NSSet set defers: @ [@ "text / plain", @ "text / html"]]; [Opset Set Scriiler: Serializer]; By:   
 From:  
 
 By default, the following MIME type accepts, in which the official standard, application / JSN, as well as other commonly used Type:  
  application / json text / json    
 You do not have to use  AFJSONResponseSerializer  You can create your own serializer, as long as it complies with the protocol.  
 If you have  JSON  responses but the  XML  error responses, then you can only sub-class  AFHTTPResponseSerializer  Do processing.  
 You can also use different paragraph types to parse, which you are going through the serializer giving it.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
