我有一个自定义按钮动画，它在视图中。现在我在向按钮添加动作时遇到问题。这是代码。 LogOut是按钮，我不知道如何在其上添加操作以将用户注销。
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
}
答案 0 :(得分：0)
替换VMButtonCircleFun.h和VMButtonCircleFun.m中的所有代码并检查更新的UIViewController代码，
问题是你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，所以我定义了一个方法来添加自定义目标，在这种情况下你的ViewController并在那里调用选择器
