ios - 识别哪个View调用Tap函数

Question

我知道如何向 UIImageView 添加可点击性，但是，有 2 个 ImageView ，我想区分它们以调用正确的函数。但是，我似乎无法获得正确的发件人。

 func addTappability (view imageView:UIImageView){
    //add tapping function for image

    let tapGestureRecognizer = UITapGestureRecognizer(target:self, action:#selector(IdCardViewController.imageTapped(_:)))
    imageView.isUserInteractionEnabled = true
    imageView.addGestureRecognizer(tapGestureRecognizer)
}

func imageTapped(_ sender: UIImageView) {

    //Problem here, can't get correct sender
    if ( sender == photoImageViewLeft) {
        //do one thing
    }else {
        //do the other
    }
}

用这个替换你的函数:

func imageTapped(_ sender: UITapGestureRecognizer) {

    if let imageView = sender.view as? UIImageView {
        if ( imageView == photoImageViewLeft ) {
            print("Image1 Tapped")
        }else {
            print("Image2 Tapped")
        }

    }
}
