What is the correct way to create singletone subclass of AFHTTPSessionManager with custom session configuration?
class DefaultSessionConfiguration: NSURLSessionConfiguration {
override init () {
super.init()
self.HTTPShouldSetCookies = true
HTTPCookieStorage?.cookieAcceptPolicy = NSHTTPCookieAcceptPolicy.Always
HTTPAdditionalHeaders = [ "Content-Type": "application/json"];
}
}
let baseUrl = "https://google.com"
class HTTPManager: AFHTTPSessionManager {
static let _sharedAPIManager = HTTPManager(baseURL: NSURL(string: baseUrl)!, sessionConfiguration:DefaultSessionConfiguration())
class var sharedInstance : HTTPManager {
return _sharedAPIManager
}
override init(baseURL url: NSURL!, sessionConfiguration session:NSURLSessionConfiguration? ) {
super.init(baseURL: url, sessionConfiguration: session)
self.responseSerializer = AFJSONResponseSerializer() as AFJSONResponseSerializer
self.requestSerializer = AFJSONRequestSerializer() as AFJSONRequestSerializer
}
}
While trying to use this code as self.sessionManager = HTTPManager.sharedInstance it is always crashed with message
[MyApp.DefaultSessionConfiguration setHTTPShouldSetCookies:]: unrecognized selector sent to instance 0x7f99f8f31b70
but MyApp.DefaultSessionConfiguration is subclass of NSURLSessionConfiguration and defenetly has this method.
So, how do we solve this problem?
The issue is that you shouldn't be instantiating a NSURLSessionConfiguration directly. You should instantiate it by calling one of the following class methods: defaultSessionConfiguration, ephemeralSessionConfiguration or backgroundSessionConfigurationWithIdentifier. For example:
let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
configuration.HTTPShouldSetCookies = true
configuration.HTTPCookieStorage?.cookieAcceptPolicy = .Always
