使用NSKeyedUnarchiver类来进行相互转换

1、NSDictionary转NSData

var dictionaryExample : [String:AnyObject] = ["user":"UserName", "pass":"password", "token":"0123456789", "image":0] 
let dataExample : NSData = NSKeyedArchiver.archivedDataWithRootObject(dictionaryExample)

2、NSData转NSDictionary

let dictionary:NSDictionary = NSKeyedUnarchiver.unarchiveObjectWithData(dataExample)! as NSDictionary
