当我在模拟器中按下 Apple TV 游戏手柄按钮时，它们不会触发

Question

我在 Apple TV 模拟器中遇到问题。我有 Xcode 9.4 并且正在使用 Nimbus 无线控制器。我有一个游戏的菜单屏幕，它不注册扩展游戏手柄上的按钮点击。当我使用它们时，模拟器会看到摇杆和方向键并进行注册，但没有一个按钮起作用。这是我的代码。这是代码。有人可以回顾一下这个并告诉我为什么他们认为这不起作用吗？谢谢，格雷格

Answer 1

我找到了我的问题。我需要使用buttonA ==元素而不是buttonA.isPressed。

Answer 2

除此之外，tvOS 模拟器无法识别 GCMicroGamepad。

https://developer.apple.com/documentation/gamecontroller/gccontroller/1627772-microgamepad

它只能识别使用与 Mac 配对的物理 MFi 设备的扩展游戏手柄。

要测试 GCMicroGamepad，您需要将 Test Flight 与物理 Apple TV 结合使用。

如果您为 tvOS 启用 GCMicroGamepad，实体 Apple TV 会自动将 Siri Remote 识别为微型游戏手柄。它不适用于 tvOS 模拟器。
