I'm showing an alert view to be able to rename a Book when selected. I am Having issues retrieving the input from the user.
here is my code:
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { let optionMenu = UIAlertController(title: nil, message: "Choose Option", preferredStyle: .ActionSheet) let newBookAction = UIAlertAction(title: "Add New Book", style: .Default, handler: { (alert: UIAlertAction!) -> Void in var alert = UIAlertController(title: "Add New Book", message: "What is the Name of the New Book?", preferredStyle: UIAlertControllerStyle.Alert) alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)) alert.addTextFieldWithConfigurationHandler { (textField) in textField.placeholder = "New Book Name" } self.currentShelf.addNewBook(Book(bookName: self.alert.textFields[0] as String)) self.presentViewController(alert, animated: true, completion: nil) self.tableView.reloadData() println("Book Added") }) let deleteAction = UIAlertAction(title: "Delete", style: .Default, handler: { (alert: UIAlertAction!) -> Void in self.currentShelf.allBooksOnShelf.removeAtIndex(indexPath.row) self.tableView.reloadData() println("Book Deleted") }) let updateAction = UIAlertAction(title: "Update", style: .Default, handler: { (alert: UIAlertAction!) -> Void in println("Book Updated") }) let readAction = UIAlertAction(title: "Read", style: .Default, handler: { (alert: UIAlertAction!) -> Void in if self.currentShelf.allBooksOnShelf[indexPath.row].hasBeenRead == false{ self.currentShelf.allBooksOnShelf[indexPath.row].hasBeenRead = true var alert = UIAlertController(title: "Read Book", message: "Thanks For Reading!", preferredStyle: UIAlertControllerStyle.Alert) alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)) self.presentViewController(alert, animated: true, completion: nil) println("Book Read") } else{ self.currentShelf.allBooksOnShelf[indexPath.row].hasBeenRead = false var alert = UIAlertController(title: "Unread Book", message: "You Just UnRead A Book...", preferredStyle: UIAlertControllerStyle.Alert) alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)) self.presentViewController(alert, animated: true, completion: nil) println("Book Unread") } }) let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: { (alert: UIAlertAction!) -> Void in println("Cancelled") }) optionMenu.addAction(newBookAction) optionMenu.addAction(readAction) optionMenu.addAction(updateAction) optionMenu.addAction(deleteAction) optionMenu.addAction(cancelAction) self.presentViewController(optionMenu, animated: true, completion: nil) } the spot I'm running into trouble is:
let newBookAction = UIAlertAction(title: "Add New Book", style: .Default, handler: { (alert: UIAlertAction!) -> Void in var alert = UIAlertController(title: "Add New Book", message: "What is the Name of the New Book?", preferredStyle: UIAlertControllerStyle.Alert) alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil)) alert.addTextFieldWithConfigurationHandler { (textField) in textField.placeholder = "New Book Name" } self.currentShelf.addNewBook(Book(bookName: self.alert.textFields[0] as String)) self.presentViewController(alert, animated: true, completion: nil) self.tableView.reloadData() println("Book Added") }) i hope this is a simple fix, and i appreciate any help. thanks!
