使用 UISlider 无需用户交互
我有一个自定义的 UISlider，我想用它来向用户显示信息，但我不希望用户能够与滑块交互。我已经尝试过
mySlider.enabled = NO;
，但滑块变灰，这看起来不像我想要的样子。
那么，如何将 UIControl 设置为禁用而不将其“灰化”。
I've got a customized UISlider that I want to use to display information to the user with and I don't want the user to be able to interact with the slider. I've tried
mySlider.enabled = NO;
but the slider becomes greyed out, which does not look the way I want it to look.
So, how do I set a UIControl to disabled without "greying" it out.

您不认为呈现一个不响应触摸的已启用滑块会让用户感到困惑吗？ UISlider 不仅仅显示信息，它还告诉用户该信息是用户可调的。
您应该设计出自己的信息显示，但用户无法对其进行调整。
Don't you think it's going to confuse users to present an enabled slider that doesn't respond to touches? A UISlider doesn't just display information, it also tells the user that the information is user-adjustable.
You should come up with your own information display that doesn't look user-adjustable.
userInteractionEnabled 可能不适用于 UISlider （以及为什么它存在？），但它适用于它的超级视图。因此，尝试将 UISlider 附加到另一个辅助（透明？）NSView，然后为此辅助视图设置 userInteractionEnabled = NO。
userInteractionEnabled probably doesn't works for the UISlider (and why it exists??) but it works for its superview. So, try attaching the UISlider to another auxiliary (transparent?) NSView and then set userInteractionEnabled = NO to this auxiliary view.
