Question

我的项目上有一个图像滑块。当我点击它时，我想获取图像的ID。到目前为止，我已经做到了。

为了获取ID，我创建了一个操作按钮-

    @IBAction func onTapGetBannerId(_ sender: Any) {
       //  var bannersArray = [BannersHome]() //banner array contain image and it's id
        for items in bannersArray {
            print(items.banner_id) 
        }
      // print(bannersArray[0].banner_id)
    }

在图像上点击我会得到所有ID。不是我点击的那张图片的特定ID，我知道为什么要得到这个，但是我想要我点击的那张图片的特定ID-

这是我剩下的代码-

func setBannerImages(_ bannerArray: [BannersHome]) {

        totalFirstCount = bannerArray.count
        if totalFirstCount == 1 {
            // bannerImage.yy_imageURL = URL(string: bannerArray[0].banner_image)

            bannerImage.kf.setImage(with: URL(string: bannerArray[0].banner_image))
            print("banner id------------\(bannerArray[0].banner_id)")
        }
        else if !isFirstStarted && (totalFirstCount > 1) {
            isFirstStarted = true
            totalFirstCount = 0
            self.perform(#selector(self.setImage), with: bannerArray, afterDelay: 0.3)
        }
    }

 func setImage(_ thumbArray: [BannersHome]) {

        if currentFirst == thumbArray.count {
            currentFirst = 0
        }
        let transition = CATransition()
        transition.duration = 0.4
        transition.type = kCATransitionFade
        bannerImage.layer.add(transition, forKey: kCATransition)
        bannerImage.kf.setImage(with: URL(string: thumbArray[currentFirst].banner_image))
        // bannerImage.yy_imageURL = URL(string: thumbArray[currentFirst].banner_image)
        currentFirst += 1
        self.perform(#selector(self.setImage), with: thumbArray, afterDelay: 2.0)
    }

我的模特-

class BannersHome: NSObject {

    var banner_image:String!
    var banner_id:String!

    init(BannersHome: NSDictionary) {

        self.banner_image = BannersHome["banner_image"] as? String
         self.banner_id = String(BannersHome["banner_id"] as! NSInteger)
    }
}

我想获取我点击的图像的ID。我怎么能做到这一点？谢谢。

您可以使用视图的tag属性

设置

的标签

 bannerImage.tag = currentFirst

然后在onTapGetBannerId中获取发件人的标签

let imageView = sender as! UIImageView

// Do what you have to with the index
let index = imageView.tag
