ios - UIview下的UIButton无法触摸

Question

我在 UIView 下添加了 UIButton 但我添加了它无法触及的操作目标:

这是我的代码:

testview.swift

import UIKit

class testview: UIView {
    @IBOutlet var comment:UIButton!
    }

在viewconrtroller.swift

中

class ViewController:UIViewController,UIScrollViewDelegate{
@IBOutlet var inner:testview!
@IBOutlet var sc: UIScrollView!
     override func viewDidLoad() {
        super.viewDidLoad()
        sc.delegate = self
        sc.isScrollEnabled = true
        sc.delaysContentTouches = false
        sc.contentSize = CGSize(width:320, height:1805)
        inner.isUserInteractionEnabled = true
        inner.isExclusiveTouch = true
        inner.comment.isEnabled = true
        inner.comment.addTarget(ViewController(), action: #selector(touched(_:)), for: .touchUpInside)
}
@IBAction func fullcomment(_ sender: UIButton) {
        print("touched")
}

改变

inner.comment.addTarget(ViewController(), action: #selector(touched(_:)), for: .touchUpInside)

到

inner.comment.addTarget(self, action: #selector(fullcomment(_:)), forControlEvents: .TouchUpInside)
