swift 开发 - NSDictionary与NSData互转

1、NSDictionary转NSData

 let data: NSData = NSKeyedArchiver.archivedData(withRootObject:dataDic) as? NSData ?? NSData()

2、NSData转NSDictionary

let dic = NSKeyedUnarchiver.unarchiveObject(with: data as? Data)as!NSDictionary

3、NSDictionary转Data

let date = try? JSONSerialization.data(withJSONObject: dic, options: .prettyPrinted)

4、Data转Dictionary

let json = try? JSONSerialization.jsonObject(with: data, options: .mutableContainers)as! Dictionary<String,String>
