问题
If a user decides to not allow an app to access cellular data every time they try to open the app they are shown a warning telling them that cellular data is turned off. Is there a way in the SDK to stop showing this message or control when / where it is displayed?
回答1:
The system will show this message if you try to access the Internet when permission has been revoked. To prevent it from appearing, you could use Apple's Reachability code to detect network availability, and only make web calls if the network is available.
