我的应用程序看起来很暗,我不知道它是否真的很重要,但我正在我的应用程序上制作动画(复杂的 UI - 自定义滑出菜单),然后在我做的一切都很好并且我的黑暗外观的布局看起来很好,每次我出于某种原因按下一个按钮时,它都会用动画覆盖按钮,尽管使用背景和 zstack 让在后台显示但从不显示..请帮我找出问题..
我的代码

var corners : UIRectCorner
var radius: CGFloat
func path(in rect: CGRect) -> Path {
let path = UIBezierPath(roundedRect: rect, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius))
return Path(path.cgPath)
}
}
