启用键盘
- 从 App Store 安装双拼，并打开应用一次。
- 前往设置 → 通用 → 键盘 → 键盘 → 添加新键盘。
- 在第三方键盘中选择双拼。
- 返回任意文本框，长按地球键并选择双拼。
无需开启“允许完全访问”。双拼键盘不请求、也不需要这项权限。
常见问题
为什么 iOS 会自动切换到其他键盘？
在密码等安全输入框中，iOS 会自动使用系统键盘；某些电话号码输入框也可能使用专用键盘。第三方键盘无法更改这一系统行为。
长按地球键时找不到双拼
请先确认“设置 → 通用 → 键盘 → 键盘”中已经列出双拼。如果已经添加，请关闭并重新打开当前应用。重新启动设备也可以刷新系统键盘列表。
双拼需要“允许完全访问”吗？
不需要。候选词转换和词频学习均在本机进行。
学习数据保存在哪里？
学习到的词频保存在键盘扩展的本地存储中，不会传输给开发者。
使用哪一种双拼方案？
本应用使用小鹤双拼方案。请查看完整键位图。
支持哪些设备？
双拼支持运行 iOS 15 或更高版本的 iPhone 和 iPad，并支持横屏和竖屏。

Common questions
Why does iOS switch away from ShuangPin?
iOS uses the system keyboard in secure password fields and may select a specialized keyboard for some phone-number fields. Third-party keyboards cannot override this behavior.
I cannot find ShuangPin under the globe key.
Confirm that ShuangPin appears in Settings → General → Keyboard → Keyboards. If it does, close and reopen the app containing the text field. Restarting the device can also refresh the system keyboard list.
Does ShuangPin need Full Access?
No. Candidate conversion and word-frequency learning happen on the device.
Where is learned data stored?
Learned word frequencies remain in the keyboard extension’s local storage and are not transmitted to the developer.
Which layout does it use?
ShuangPin uses the Xiaohe layout. See the complete layout reference.
Which devices are supported?
ShuangPin supports iPhone and iPad running iOS 15 or later, in portrait and landscape.
