今日、OS XやiOSで設定やその他のプログラムデータを保存するいくつかの側面についてお話ししたいと思います。 いつものように、いくつかのオプションがあります：Core Data、裸のSQLite、バイナリ形式、テキスト形式、NSUserDefaults、そして聞いたことがあると思いますが、 PLISTのようなファイル 、つまりXML P roperty Listです。
要するに、plistファイルは単純なXMLですが、いくつか注意点があります。 たとえば、タグ内のタグの順序はいくつかのルールによって決定されます。キーと値のペアになりますが、キータイプのタグと値タイプのタグは同じレベルにあります。 典型的な例：
<key>identifier</key> <string>j3qq4-h7h2v</string>
Plistは、NSString、NSNumber（int、float、BOOL）、NSDate、NSArray、NSDictionary、NSDataの主要なCocoaデータ型を保存できます。 次のタグは、これらのタイプに対応しています：
