すぐにNSUserDefaultsに配列を書き込むことができません

Question

オブジェクトだけではなくオブジェクトの配列を追加してNSUserDefaultsに書き込もうとしています。

しかし、私はこのエラー

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Attempt to insert non-property list object (
"MyNotificaiton", 
"MyNotificaiton" 
) for key pushArray' 

を取得し、私はかなり確信して、これは私が挿入しようとしている配列は、右のタイプではないことを意味しますが、私は修正するためにそれを行うために必要なものを知っていませんそれ。

これは私がこれまで

Answer 1

あなたが代わりにこのようにそれを行うには、あなたがしようとしている方法で配列を保存することはできません持っているものです。

let arr = ["1", "2", "3"] 

let dataSave = NSKeyedArchiver.archivedDataWithRootObject(arr) 
NSUserDefaults.standardUserDefaults().setObject(dataSave, forKey: "array") 
NSUserDefaults.standardUserDefaults().synchronize() 


let data = NSUserDefaults.standardUserDefaults().objectForKey("array") 
let savedArray = NSKeyedUnarchiver.unarchiveObjectWithData(data! as! NSData) 

print(savedArray!)
