Ios Swift：如何使用单击按钮UITableVieCell创建UIActionSheet

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

我的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!;
}

只需在ViewController中添加onMenubtnClick方法，而不是单元格

将此添加到您的

cellForRowAt

方法中

cell.youtBtn.addTarget(self, action: #selector(self.btnMenu(_:)), for: .touchUpInside)

在ViewController中添加此代码

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

---

在单元类中制作按钮的插座

然后在使用此单元格的tableView中，在

cellforrowatinexpath

  cell.yourButton.addTarget(self, action: #selector(yourButtonTapped), for: .touchDown)

现在，在您的

yourButtonTapped

方法中，按照链接编写操作表代码：

希望它有帮助

试试这个，在UserTableViewCell中做一些更改

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)
    }
}

并修改此方法

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!;
}

闭合法 1-在UserTableViewCell中声明actionBlock

import UIKit

class UserTableViewCell: UITableViewCell {

    @IBOutlet weak var nameLabel: UILabel!
    var actionClosure : (()->Void)? = 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
    }

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

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

    @IBAction func btnDial(_ sender: UIButton) {

    }

}

2-在单元格操作中执行操作块

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

    let cell = tableView.dequeueReusableCell(withIdentifier: "UserTableViewCell", for: indexPath) as! UserTableViewCell
    cell.actionClosure = { [weak self] in
        //SHow your ActionSheet Here
    }
    return cell

}

3-设置单元格块操作，调整cellForRowAtIndexPath方法

完整代码

CellForRow实施

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

    let cell = tableView.dequeueReusableCell(withIdentifier: "UserTableViewCell", for: indexPath) as! UserTableViewCell
    cell.actionClosure = { [weak self] in
        //SHow your ActionSheet Here
    }
    return cell

}

表格视图单元格

import UIKit

class UserTableViewCell: UITableViewCell {

    @IBOutlet weak var nameLabel: UILabel!
    var actionClosure : (()->Void)? = 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
    }

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

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

    @IBAction func btnDial(_ sender: UIButton) {

    }

}

在目标cit的目标c中选中此答案@Reinier答案。您需要使用委托模式。选中此项：

import UIKit

class UserTableViewCell: UITableViewCell {

    @IBOutlet weak var nameLabel: UILabel!
    var actionClosure : (()->Void)? = 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
    }

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

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

    @IBAction func btnDial(_ sender: UIButton) {

    }

}
