动画时的UserInteraction

Question

我正在以圆形方式围绕视图旋转几个圆形按钮。在旋转时，如果用户单击任何按钮，则不会发生任何事件。 使用下面的代码。 请参见addButton函数的代码。这就是我添加按钮的方式。然后创建TrieView对象并将其添加到目标视图中，然后调用addAnimation方法。

import Foundation

class TribeView: UIView {
 var circleTapBlock:((Int) -> Void)?
 var nameLabel:UILabel!
 var type = CircleType.TribeHomeCenter
 var index = 99999999999

 private var bgImageView = UIImageView()
 private var whiteCircle = UIView()
 private var profilePic = AvatarImageView()
 private var titleLabel = UILabel()

enum CircleType {
    case TribeHomeCenter
    case TribeHomeOrbit
}

var isFreeSize:Bool {
    switch type {
    case .TribeHomeCenter,.TribeHomeOrbit:
        return false
    }
}

var bgImageTopConstant:CGFloat{
    switch type {
    case .TribeHomeCenter:
        return -22
    case .TribeHomeOrbit:
        return -22
    }
}

static func viewSize(for type:CircleType) -> CGSize {
    switch type {
    case .TribeHomeCenter:
        return CGSize(width: 80, height: 100)
    case .TribeHomeOrbit:
        return CGSize(width: 60, height: 80)
    }
}


var bgImagesize:CGSize{
    switch type {
    case .TribeHomeCenter:
        return CGSize(width: 135, height: 135)
    case .TribeHomeOrbit:
        return CGSize(width: 100, height: 100)
    }
}

var whiteCircleize:CGSize{
    switch type {
    case .TribeHomeCenter:
        return CGSize(width: 50, height: 50)
    case .TribeHomeOrbit:
        return CGSize(width: 40, height: 40)

    }
}

var profilePicSize:CGSize{
    switch type {
    case .TribeHomeCenter:
        return CGSize(width: 48, height: 48)
    case .TribeHomeOrbit:
        return CGSize(width: 38, height: 38)

    }
}

var titleLabelSize:CGSize{
    switch type {
    case .TribeHomeCenter:
        return CGSize(width: TribeView.viewSize(for: type).width, height: 20)
    case .TribeHomeOrbit:
        return CGSize(width: TribeView.viewSize(for: type).width, height: 20)
    }
}

var titleLabelTopConstant:CGFloat{
    switch type {
    case .TribeHomeCenter:
        return 80
    case .TribeHomeOrbit:
        return 60

    }
}

var titleFont:UIFont {
    switch type {
    case .TribeHomeCenter:
        return UIFont(name: UIFont.cineBeeRegular, size: 13)!
    case .TribeHomeOrbit:
        return UIFont(name: UIFont.cineBeeRegular, size: 11)!

    }
