class AppDelegate: UIResponder,UIApplicationDelegate {
var window: UIWindow?
var navigationController: UINavigationController?
var mainDic:NSMutableDictionary?

代码设置mainDic

func filterResponse(response:NSDictionary){
 
    var appDelegate=AppDelegate()
    appDelegate.mainDic=response.mutableCopy() as? NSMutableDictionary
}

代码来获取字典.

let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
println(appDelegate.mainDic)

问题是我得到的输出没有.请让我正确.
