配置说明

表情控件配置

//EmojiPopMenu.shared.config.xxx

    //缩放动画时间、选中后轨迹动画时间
    public var animationTime: TimeInterval = 0.33
    //true -> 轨迹会根据目标视图进行大小缩放，false ->默认缩放
    public var isTraceTargetView: Bool = true
    //表情间距
    public var itemSpace: CGFloat = 10
    //表情大小
    public var itemSize: CGSize = CGSize(width: 34, height: 34)
    //表情位于选中状态放大倍数
    public var itemZoomInScale: CGFloat = 1.55
    //其他表情位于选中状态时，表情的缩小倍数
    public var itemZoomOutScale: CGFloat = 0.88
    //表情托盘padding
    public var contentEdge: UIEdgeInsets = .init(top: 10, left: 12, bottom: 10, right: 12)
    //长按移动时垂直区域额外触发距离
    public var touchInZoomVerticalExt: CGFloat = 20

    public var titleLabelConfig: EmojiPopMenuTitleLabelConfig = EmojiPopMenuTitleLabelConfig()
    //锚点视图是否根据上下边显示自动旋转
