ios - 向自定义按钮添加操作

Question

我有一个自定义按钮动画及其内部 View 。现在我在向按钮添加操作时遇到问题。这是代码。 LogOut 是按钮，我不知道如何在其上添加操作来注销用户。

class exampleViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    self.view.backgroundColor = UIColor.white
    self.addCircleView()
    // Do any additional setup after loading the view, typically from a nib.
}

func addCircleView() {
    var circleView1 = VMButtonCircleFun(frame: CGRect(x: CGFloat(0), y: CGFloat(0), width: CGFloat(60), height: CGFloat(60)))
    circleView1.addCircleLayer(withType: VMMakeLocation.top.rawValue)
    circleView1.strokeColor = UIColor(red: 243/255, green: 106/255, blue: 106/255, alpha: 1.0)
    circleView1.center = CGPoint(x: CGFloat(self.view.bounds.width / 2 - 100), y: CGFloat(self.view.bounds.height / 2))
    circleView1.setIconButton(UIImage(named: "Layer 14.png")!, withType: VMMakeLocation.top.rawValue, with: UIColor(red: 127/255, green: 140/255, blue: 141/255, alpha: 1.0))
    circleView1.setLineWidthValue(1.0)
    self.view.addSubview(circleView1)
    circleView1.buildButton()
    circleView1.addTarget(self, action: #selector(self.logout), forControlEvents: .TouchUpInside)
}

func logout()
{
    //TODO MAKE YOUR LOGOUT STUFFS
}

将VMButtonCircleFun.h和VMButtonCircleFun.m中的所有代码替换为这一段，并检查UIViewController的代码更新，

问题是您的自定义类在它自己的类上调用选择器，而不是使用自定义目标，因此我定义了一个方法来添加自定义目标(在本例中为 ViewController)并在那里调用选择器
