点击手势返回错误[重复]

Question

我正在尝试让点击手势打印一行，但它不断返回并显示以下错误：

libc++abi.dylib：以 NSException 类型的未捕获异常终止 (lldb)

我已将图像链接到水龙头插座，没有其他不良连接。

 override func awakeFromNib() {
    super.awakeFromNib()

    let tap = UITapGestureRecognizer(target: self, action: Selector("likeTapped:"))
        tap.numberOfTapsRequired = 1
    likeImage.addGestureRecognizer(tap)
    likeImage.isUserInteractionEnabled = true

}

 func likeTapped(sender: UITapGestureRecognizer) {
    print("yess called")
}

有没有人遇到过这种情况，有解决办法吗

感谢这篇文章，能够修复它。

How to make UITapGestureRecognizer trigger function

我将代码更改为：

  likeImage.isUserInteractionEnabled = true
    let tap = UITapGestureRecognizer(target: self, action: #selector(self.likeTapped(_:)))
        tap.numberOfTapsRequired = 1
    likeImage.addGestureRecognizer(tap)

}

 func likeTapped(_ sender: UITapGestureRecognizer) {
        print("yess called")
    }
