Phone call with Watch OS2

问题

Is it possible to start a call from the watch using Watch OS 2? I have a button in my watch os2 app and I need a way to start a call to a precompiled number from the watch or at least to start the call in the iPhone. Thanks

回答1:

Yes it is possible on WatchOS 2:

Apps can initiate telephone calls or SMS messages using the openSystemURL: method of the shared WKExtension object. When you open a URL that uses the tel or sms scheme, Apple Watch redirects that URL to the appropriate system app for handling. You can also open Passbook URLs by using the openSystemURL: method to open the URL associated with a PKPass object.
