Receive response as NSDictionary instead of NSData - ios

Question

I'm trying to get the response from the server as NSDictionary instead of NSData, so first I'm using AFNetworking library and the server request these settings to be HTTP not JSON serializer as the following :
self.responseSerializer = AFHTTPResponseSerializer() as AFHTTPResponseSerializer
self.requestSerializer = AFHTTPRequestSerializer() as AFHTTPRequestSerializer
self.requestSerializer.HTTPMethodsEncodingParametersInURI = NSSet(array: ["GET"]) as! Set<String>
self.responseSerializer.acceptableContentTypes = NSSet(objects: "application/json","text/json","text/javascript","text/html") as? Set<String>
Next is when i get the response from the server it comes to be NSData and its because I'm using AFHTTPRequestSerializer() and here is my code :
self.POST(addUserURL, parameters: dictionary, progress: nil, success: { (task, responseObject) -> Void in
print(responseObject)
}) { (task, error) -> Void in
}
Also inside AFNetworking block its not allowed to handle try and catch for NSJSONSerializtion which can be a possible solution but it doesn't work.

Answer 1

Use NSJSONSerialization for that as shown in below code :
do {
let jsonObject = try NSJSONSerialization.JSONObjectWithData(responseObject, options: .AllowFragments) as! NSDictionary
// use jsonObject here
} catch {
print("json error: \(error)")
}

As response that you get from the server doesn't have top level object that is either Array or Dictionary you have to specify custom reading options in that should be used by AFNetworking.
In order to do that you have to set responseSerializer property on an instance of AFURLSessionManager class. You can do it as follows:
let sessionManager = OLFURLSessionManager.init() //you probably want to keep session manager as a singleton
sessionManager.responseSerializer = AFJSONResponseSerializer.serializerWithReadingOptions(.AllowFragments)
//you should use that instance of session manager to create you data tasks
After that you should be able to correctly parse response from the server as follows:
