recall func after auth in uiwebview - ios

Question

In my current project i have CAS auth. I made it in modal uiwebview. My func look like:
func models(callback: ([ModelType])->()) {
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
MLMPProvider.request(MLMP.Models, completion: {
(data, status, response, error) -> () in
func checkResponse(response:NSURLResponse){
if toString(response.URL!).rangeOfString("login") != nil{
NSNotificationCenter.defaultCenter().postNotificationName("LOGIN", object: response.URL!)
}
}
checkResponse(response!)
var result: [ModelType] = []
if let data = data, let models = JSON(data: data, options: NSJSONReadingOptions.allZeros, error: nil).array {
for model in models {
if let modelId = model["uuid"].string {
result += [.Custom(modelId)]
}
}
}
callback(result)
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
})
}
My question is: What is the best way to recall models with callback after auth? Maybe i can do some magic with selectors?

Answer 1

I solve my problem
i add vars to my network layer
var closure:Any!
var methodName:String!
and add notification callback when i get token from server
#objc private func authTokenGetted(notification: NSNotification){
recallMethodWith(methodName, andcallback: closure)
}
func recallMethodWith(name:String, andcallback: Any){
switch name{
case MethodsName.models:
models(andcallback as! ([ModelType])->())
case MethodsName.model:
println("modelcall")
default:
println(name)
}
}
init(){
NSNotificationCenter.defaultCenter().addObserver(self, selector: "authTokenGetted:", name: "AuthDone", object: nil)
}
and my models func looks like:
func checkResponse(response:NSURLResponse) -> Bool{
if toString(response.URL!).rangeOfString("login") != nil{
NSNotificationCenter.defaultCenter().postNotificationName("LOGIN", object: response.URL!)
return false
}
return true
}
func models(callback: ([ModelType])->()) {
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
self.methodName = __FUNCTION__
self.closure = callback
MLMPProvider.request(MLMP.Models, completion: {
(data, status, response, error) -> () in
if self.checkResponse(response!){
var result: [ModelType] = []
if let data = data, let models = JSON(data: data, options: NSJSONReadingOptions.allZeros, error: nil).array {
for model in models {
if let modelId = model["uuid"].string {
result += [.Custom(modelId)]
}
}
}
callback(result)
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
}
})
}
