使用NSKeyedUnarchiver类来进行相互转换

1、NSDictionary转NSData

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

2、NSData转NSDictionary

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