How is camera, usb and bluetooth access implemented in Qt for iOS?

Question

iOS

I am interested in developing applications for ios in qt. It is clear from the documentation that it is possible to build a simple application and run it on a smartphone. It is not clear how access to the camera, USB and bluetooth is carried out. What approaches can be used?

Answer 1

They wrote native code, and call it under the hood from their standard classes for working with the camera, bluetooth, etc. If there is something missing in the standard classes, then you also need to write native code.
