多语言
說明：依系統設定的語言自動切換適合的顯示字串
操作：
在Interface Builder設計時的介面
若系統設定為English則顯示英文介面
若系統設定為繁體中文則顯示為中文介面
如何建立自定的語系檔：
1.在Resources分類下新增檔案 [右鍵/Add/New File...]
2.在範本的分類選擇Other後再選擇 Strings File
3.將存檔檔名設定為 Localizable.strings
4.在 Localizable.strings 檔案上按右鍵並選擇 Get Info
5.選擇左下方的 Make File Localizable
6.將分頁標籤切換至General
7.選擇左下方的 Add Localization
8.輸入新的語系名稱 zh_TW 後按 Add
9.您會看到目前您設定了English及zh_TW兩種語系
10.在檔案清單中您將看到 Localizable Strings (English) 及 Localizable String (zh_TW)
11.開啟後編輯語言字串就可以囉，範例如下：
Localizable.strings (English)
/*

*/
"DemoTitle"="This is English Version";
"String1"="Apple";
"String2"="BAnana";
"String3"="Orange";
"String4"="Watermelon";
"String5"="Strawberry";

"DemoTitle"="這是繁體中文的版本";
"String1"="蘋果";
"String2"="香蕉";
"String3"="橘子";
