I tried making a ThirdPersonCPP iOS client mode package with following step:
1.created a ThirdPersonCPP Example project on a Mac.
2.add a ‘ThirdPersonCPPClient.Target.cs’ into the project.
3.built it with xcode. After then run it in the UE editor.
4.set the ‘Build Configuration’ to be ‘Development Client’.
5.package the project for ios platform.
6.install the *Client.ipa in a iphone device.
But the result was that the app is just standalone mode not client, It would enter the scene directly without connecting server.
Btw, I clicked ‘Play’ in editor with ‘run dedicated server’, it worked well.
