Swift:如何通过单击按钮 UITableVieCell 创建 UIActionSheet [英] Swift: How to create UIActionSheet with click on button UITableVieCell

问题描述

我有一个带按钮的 tableview，当我点击 3 点按钮时，我想在这里创建一个 UIActionSheet.这是一个自定义的tableview单元格.

I have a tableview with buttons, and I would like to create a UIActionSheet here when I click on the 3 dots button. It is a custome tableview cell.

我的 UITableViewCell:

My UITableViewCell:

import UIKit

class UserTableViewCell: UITableViewCell {


@IBOutlet weak var nameLabel: UILabel!

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
}

func view(with user: User){
    nameLabel.text = user.getName();
}

@IBAction func btnMenu(_ sender: UIButton) {
    //here I want to execute the UIActionSheet
}

@IBAction func btnDial(_ sender: UIButton) {

}

}

在我的视图控制器中:

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return users.count;
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "userCell", for: indexPath) as? UserTableViewCell;

    cell?.view(with: users[indexPath.row]);

    return cell!;
}

推荐答案

试试这个并在 UserTableViewCell 中做一些改变

Try this and do some changes in UserTableViewCell

class UserTableViewCell: UITableViewCell {
    weak var myVC : UIViewController?
    @IBAction func btnMenu(_ sender: UIButton) {
        //here I want to execute the UIActionSheet
        let actionsheet = UIAlertController(title: nil, message: nil, preferredStyle: UIAlertControllerStyle.actionSheet)

        actionsheet.addAction(UIAlertAction(title: "Take a Photo", style: UIAlertActionStyle.default, handler: { (action) -> Void in
        }))

        actionsheet.addAction(UIAlertAction(title: "Choose Exisiting Photo", style: UIAlertActionStyle.default, handler: { (action) -> Void in
        }))
        actionsheet.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel, handler: { (action) -> Void in

        }))
        myVC?.present(actionsheet, animated: true, completion: nil)
    }
}

并修改这个方法

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "userCell", for: indexPath) as? UserTableViewCell;

    cell?.view(with: users[indexPath.row]);
    cell?.myVC = self
    return cell!;
}
