苹果在 iOS 27.2 Beta 2 中为中国区用户新增了"限制运动数据"（Restrict Motion Data）功能1。该功能位于"设置-隐私与安全-运动与健身"中，允许用户限制特定应用获取加速度计、陀螺仪等运动传感器数据的权限1。
被限制的应用在无法访问传感器数据后可能出现闪退或其他异常1。该功能的设计目的可能用于限制应用通过摇晃手机触发广告跳转等行为1。
目前该功能仅在使用中国大陆 App Store 账号登录时显示，切换至其他地区账号后入口会消失1。用户使用中国账号设置的限制在切换到其他地区账号后也会失效1。作为测试版功能，其具体用途尚未得到苹果的正式说明，功能的名称、位置和可用范围在正式版发布时均可能发生变化1。
Apple has rolled out a new "Restrict Motion Data" feature in iOS 27.2 Beta 2 specifically for Chinese mainland users, allowing them to limit app access to motion sensors such as accelerometers and gyroscopes 1. The functionality is located in Settings under Privacy & Security > Motion & Fitness, and enables users to block specific applications from obtaining data generated by these hardware components 1.
The feature appears designed to prevent apps from triggering advertisement redirects through shake gestures, though Apple has not officially clarified its intended purpose 1. When motion data access is restricted for an app, some applications may experience crashes or other abnormal behavior due to lost sensor permissions 1. Currently, the option is visible only to users logged into their China mainland App Store account; switching to a US regional account causes the setting to disappear 1. Restrictions configured under a Chinese account become ineffective once the user switches to an American account 1.
The feature remains in testing phase as part of iOS 27.2 Beta 2, and the final version may see changes to the function name, menu location, and availability scope 1.
