识别哪个View调用Tap功能

Question

我知道如何向UIImageView添加tappability，但是，有2个图像视图，我想区分它们以调用正确的函数。但是，我似乎无法得到正确的sender。

 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
    }
}

Answer 1

用以下功能替换您的功能：

PATINDEX

Answer 2

您需要在故事板或代码中添加imageView的标签。

然后在你的imageTapped（）方法中比较它们 -

func imageTapped(_ sender: UIImageView) {

//Problem here, can't get correct sender
if ( sender.tag == 1) {
    //do one thing
}else if(sender.tag ==2){
    //do the other
}

}
