如何用swift激活操作表button？

我正在寻找一种方法来链接用户操作工作表的button

我做了删除button的function，但我需要的报告button，使用户能够发送电子邮件，如何做到这一点迅速？ 谢谢

override func tableView(tableView: UITableView,editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? { var ReportAction = UITableViewRowAction(style: .Default, title: "Report User", handler: {(action: UITableViewRowAction! , indexPath:NSIndexPath!) -> Void in let ReportMenu = UIAlertController(title: nil, message: "Report using", preferredStyle: UIAlertControllerStyle.ActionSheet) let Reportbutton = UIAlertAction(title: "E-Mail", style: .Default , handler: nil) ReportMenu.addAction(Reportbutton) self.presentViewController(ReportMenu, animated: true, completion: nil) }) var DeleteButton = UITableViewRowAction(style: UITableViewRowActionStyle.Default , title: "Delete", handler: { (action:UITableViewRowAction!, indexPath:NSIndexPath!) -> Void in self.Array1.removeAtIndex(indexPath.row) self.Array2.removeAtIndex(indexPath.row) self.Array3.removeAtIndex(indexPath.row) self.Array4.removeAtIndex(indexPath.row) self.Array5.removeAtIndex(indexPath.row) self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade) } ) return [DeleteButton , ReportAction] }

你可以这样做：

 let Reportbutton = UIAlertAction(title: "E-Mail", style: UIAlertActionStyle.Default) { (alert) -> Void in //Your code } 

以下是您发送电子邮件的示例代码：

 import UIKit import MessageUI class TableViewController: UITableViewController, MFMailComposeViewControllerDelegate { var tabledata = ["1","2","3","4"] override func viewDidLoad() { super.viewDidLoad() } // MARK: - Table view data source override func numberOfSectionsInTableView(tableView: UITableView) -> Int { return 1 } override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return tabledata.count } override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell // Configure the cell... cell.textLabel?.text = tabledata[indexPath.row] return cell } override func tableView(tableView: UITableView,editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? { var ReportAction = UITableViewRowAction(style: .Default, title: "Report User", handler: {(action: UITableViewRowAction! , indexPath:NSIndexPath!) -> Void in let ReportMenu = UIAlertController(title: nil, message: "Report using", preferredStyle: UIAlertControllerStyle.ActionSheet) let Reportbutton = UIAlertAction(title: "E-Mail", style: UIAlertActionStyle.Default) { (alert) -> Void in self.displayMailComposerSheet() } ReportMenu.addAction(Reportbutton) self.presentViewController(ReportMenu, animated: true, completion: nil) }) var DeleteButton = UITableViewRowAction(style: UITableViewRowActionStyle.Default , title: "Delete", handler: { (action:UITableViewRowAction!, indexPath:NSIndexPath!) -> Void in self.tabledata.removeAtIndex(indexPath.row) self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade) } ) return [DeleteButton , ReportAction] } override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool { return true } override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) { switch editingStyle { case .Delete: // remove the deleted item from the model self.tabledata.removeAtIndex(indexPath.row) // remove the deleted item from the `UITableView` self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade) default: return } } func displayMailComposerSheet(){ //vars var controller = MFMailComposeViewController() controller.mailComposeDelegate = self //set controller.navigationBar.tintColor = UIColor.whiteColor() //set UINavigationBar.appearance().translucent = false UINavigationBar.appearance().barTintColor = UIColor.whiteColor() UINavigationBar.appearance().tintColor = UIColor.blackColor() var attributes = NSDictionary(objectsAndKeys: UIFont(name: "HelveticaNeue-Light", size: 20)!,NSFontAttributeName, UIColor.whiteColor(), NSForegroundColorAttributeName) UINavigationBar.appearance().titleTextAttributes = attributes //set var toRecipients = NSArray(object: "[e-mail]") controller.setToRecipients(toRecipients) controller.setSubject("App Support") //show presentViewController(controller, animated: true, completion: { UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.Default, animated: true) }) } }
