Transcript

1. Extension Sharing Custom Keyboard in iOS 8
2. Grady Zhuo • iOS Developer • iOS 開發經驗2年 • 使⽤用開發語⾔言： • Objective-C • Python • Swift
3. Extension Apple’s Plan for a Powerful App Ecosystem
4. 什麼是 Extension • 為特定⺫⽬目的建制的⼆二進位檔 • 不是App • 透過Apple的Framework程式呼叫 - 不能⾃自已呼叫Extension • ⾮非App對App的IPC呼叫 - Extension也不是App • App間呼叫依然採⽤用-[UIApplication openURL:]
5. Extension的運作
6. Extension的運作(獨⽴立) Containing app App extension Host app Request Response
7. Extension的運作(間接) Containing app Shared resources Open URL App extension Host app Request Response Read/Write Read/Write
8. Extension的⽣生命週期 App extension ⽣生命週期 1.使⽤用者選⽤用Extension 4.系統刪除Extension 3. 執⾏行載具App中Extension 2.系統啟動選⽤用的Extension
9. Custom Keyboard ⾃自已的鍵盤，⾃自已刻！
10. Custom Keyboard • Bundle Configuration as App • UIKit Framework • UIInputViewController - as ViewController Life-cycle • viewDidLoad • viewWillAppear • viewDidAppear • viewWillDisappear • viewDidDisapper
11. Keyboard 呼叫流程 Custom Keyboard Text Input Object Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do ciusmod tempor incididunt ut labore et dolore Maecenas magna aliqua Running Keyboard UIInputViewController Next Keyboard View Hello UIButton insertText: Containing App Custom Keyboard Target Xcode Project App Extension Target Template hello
12. UITextDocumentProxy Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do ciusmod tempor incididunt ut labore et dolore Maecenas hello magna aliqua Running Keyboard UIInputViewController Next Keyboard View Hello textDocumentProxy <UITextDocumentProxy> UIInputViewController UIKit Framework insertText:
13. Info.plist Extended Keys • PrimaryLanguage：鍵盤主要對應的語⾔言 ex. zh-TW, en-US,… • NSExtensionPrincipalClass：Extension啟動時主要的Class ✦ Swift需完整Namespace ✦ ex. MyModule.KeyboardViewController ✦ 也可⽤用NSMainStoryboard代替 • App Extension Key參考⽂文件
14. PrimaryLanguage PrimaryLanguage
15. RequestsOpenAccess的功⽤用 • 可根據使⽤用者位置與聯絡資訊改善鍵盤 • 可與Server連線 • 可與Keyboard Containing App 進⾏行共通資源的設定 • 可同步⾄至iCloud，使所有裝置都有相同的偏好設定與資源 • 可以透過Containing App 提供In app purchase或 GameCenter⽀支援 • 需使⽤用者同意，請參閱Designing for User Trust
16. Demo
17. 建⽴立Keyboard Extension
18. 1. ⾄至專案設定加⼊入⼀一個新的Target
19. 2. 選擇Custom Keyboard
20. 3. 設定Extension專案資料
21. 4. 按Activate
22. 設定鍵盤主要語系為中⽂文
23. 5. 開啟Keyboard的Info.plist 這裡也可以從專案檔選取Target設定
24. 6.展開⾄至NSExtensionAttribute
25. 7. 修改PrimaryLanguage zh-TW就是台灣使⽤用的繁體中⽂文
