【中文标题】当我在模拟器中按下 Apple TV 游戏手柄按钮时，它们不会触发【英文标题】：Apple TV gamepad buttons not triggering when I press them in the simulator 【发布时间】：2018-06-18 02:34:09 【问题描述】：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，它没有注册扩展游戏手柄上的按钮点击。模拟器会看到摇杆和 dpad 并在我使用它们时进行注册，但没有一个按钮起作用。这是我的代码。这是代码。有人可以回顾一下并告诉我为什么他们认为这不起作用吗？谢谢，格雷格

【参考方案1】：我发现了我的问题。我需要使用 buttonA == 元素而不是 buttonA.isPressed。
