iOS审核被拒，app隐私API设置

被拒正文：

---

Your app uses the "prefs:root=" non-public URL scheme, which is a private entity. The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change.

Specifically, your app uses the following non-public URL scheme:

prefs:root=privacy&path=camera
,prefs:root=privacy
,prefs:root=privacy&path=photos

Next Steps

To resolve this issue, please revise your app to provide the associated functionality using public APIs or remove the functionality using the "prefs:root" or "App-Prefs:root" URL scheme.

If there are no alternatives for providing the functionality your app requires, you can use Feedback Assistant to submit an enhancement request.

原因：

第三方库中使用了非法API，这里是用来帮助用户跳转到app的隐私设置。

解决方式：

iOS8.0以上：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

源码跟踪：

UIKIT_EXTERN NSString *const UIApplicationOpenSettingsURLString API_AVAILABLE(ios(8.0));
