多語言支援 iphone

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)

1. /*
2. Localizable.strings
3. MultiLanguageDemo
4.

5. Created by babyfish0226 on 2009/3/6.

9. "DemoTitle"="This is English Version";
10. "String1"="Apple";
11. "String2"="BAnana";
12. "String3"="Orange";
13. "String4"="Watermelon";
14. "String5"="Strawberry";
