Swift: How to create UIActionSheet with click on button UITableVieCell - ios

Question

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.
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) {
}
}
and in my view controller:
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!;
}

Answer 1

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)
}
}
And modify this method
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!;
}

make outlets of button in cell class
then in tableView where you are using this cell write the code below in cellForRowAtIndexPath
cell.yourButton.addTarget(self, action: #selector(yourButtonTapped), for: .touchDown)
and now in your yourButtonTapped method write actionSheet code following the link :

Closure Approach
1 - Declare your actionBlock in your UserTableViewCell
var actionClosure : (()->Void)? = nil
2 - Execute your action block in your Cell Action
#IBAction func btnMenu(_ sender: UIButton) {
//here I want to execute the UIActionSheet
self.actionClosure?()
}
3 - Setup your cell block action adjusting your cellForRowAtIndexPath method
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
}
Full Code
CellForRow implementation
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
}
TableView Cell
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) {
}
}

Answer 4

just add onMenubtnClick method in your ViewControler instead of cell.
add this in your cellForRowAt method
cell.youtBtn.addTarget(self, action: #selector(self.btnMenu(_:)), for: .touchUpInside)
add this code in your ViewController
#IBAction func btnMenu(_ sender: UIButton) {
//here I want to execute the UIActionSheet
}
