Arrays 如何在表格视图单元格中点击按钮以使用UIButton打开URL？

Stackoverflow用户

我知道单元格可以打开URL，否则按钮可能无法在单元格内打开。 让我们想象一下，我正在应用程序上创建一个销售内容。我想点击那个按钮而不是细胞

资源代码：

您已经创建了两个名为DCCMerchViewController和MerchTableViewCell的swift文件夹

从故事板连接MerchTableViewCell（基于tableview单元格）

MerchTableViewCell类：UITableViewCell{

// Image
@IBOutlet weak var Merch_Image: UIImageView!

// Title
@IBOutlet weak var Merch_Title: UILabel!

// Price
@IBOutlet weak var Merch_Price: UILabel!

// Purchase
@IBAction func PurchaseMerch(_ sender: Any, linker: String) {

     UIApplication.shared.open(URL(string: linker)! as URL, options: [:], completionHandler: nil)

}


override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func setSelected(_ selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Configure the view for the selected state
  }

}

现在，您已经从情节提要（基于表视图控制器）连接到DCCMerchViewController

类DCCMerchViewController:UIViewController{

@IBOutlet weak var MerchTableView: UITableView!

}

并创建一个数组，以允许使用IndexPath.row将数组调用到单元格中

 class DCCMerchViewController: UIViewController {

    @IBOutlet weak var MerchTableView: UITableView!


    let imageMerch = ["image1", "image2"]

    let titleMerch = ["Title1", "Title2"]

    let buyLink = ["www.link.com", www.link1.com]

    let priceMerch = ["44.99", "38.99", "23.99"]


    override func viewDidLoad() {
        super.viewDidLoad()


     }

    }


And add the extension after class Storetableview (notice make sure Table View Controller connect to this UITableViewDataSource and UITableViewDelegate.) 

``` extension DCCMerchViewController: UITableViewDataSource, UITableViewDelegate {

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        // Image
        return titleMerch.count


    }



    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 128
    }




    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


        let merchCell = MerchTableView.dequeueReusableCell(withIdentifier: "MerchCells", for: indexPath) as? MerchTableViewCell

        // Image
        merchCell?.Merch_Image.image = UIImage(named: imageMerch[indexPath.row])

        // Title
        merchCell?.Merch_Title.text = titleMerch[indexPath.row]

        // Price
        merchCell?.Merch_Price.text = "Price: $\( priceMerch[indexPath.row])"

        // Purchase
        merchCell?.PurchaseMerch( AnyIndex.self, linker: "\(buyLink[indexPath.row])")
       // Kinda issues is merchCells cause this cells to open web othewise not tap those buttons... huh?

        return merchCell!

    }



 }

现在有人知道如何在点击单元格时停止打开URL，我正在尝试使用按钮打开URL。谢谢！

为单元格内的按钮创建出口，然后在

cellForRowAt

cell.btn.addTarget(self,#selector(clicked),for:touchUpInside)
cell.btn.tag = indexPath.row

---

将此添加到vc中

@objc func clicked (_ btn:UIButton) {
   UIApplication.shared.open(URL(string:buyLink[btn.tag])!, options: [:], completionHandler: nil)
}
