我可以使用任何 Titanium API 获取用户的电话号码吗？

Question

When a user runs my app (iOS or Android), can I automatically get their phone number and contact details for back up?

Answer 1

I can't vouch for Android but for iOS the answer is a definite no . Here's what Apple will say when they reject your app:

For security reasons, iPhone OS restricts an application (including its preferences and data) to a unique location in the file system. This restriction is part of the security feature known as the application's "sandbox." The sandbox is a set of fine-grained controls limiting an application's access to files, preferences, network resources, hardware, and so on."

The device's phone number is not available within your application's container. You will need to revise your application to read only within your directory container and resubmit your binary to iTunes Connect in order for your application to be reconsidered for the App Store.
