拥有一个将数据传递给ViewController的UITableViewCell。现在它崩溃了，我不知道为什么。在我之前工作时，每次点击其中一个单元格时，我就开始出现fata错误。
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var signin: UITextField!
@IBOutlet weak var password: UITextField!
private let datetimes = ["02/25/16 5:47 PM", "02/25/16 2:47 PM", "02/21/16 5:33 AM"]
private let user = ["StevieE11", "Sikes911", "MaggieMae"]
private let feedback = ["The food was fucking terrible!", "Best food this side of the mason dixon line!", "If that waiter looks at me again I'm going to bite the shit out of him"]
var sendSelectedData = NSString()
override func viewWillAppear(animated: Bool) {
navigationItem.title = "Inbox"
//navigationController!.navigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "Helvetica Neue", size: 24)!]
}
func textFieldShouldReturn(textField: UITextField!) -> Bool {
textField.resignFirstResponder()
return true
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return user.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
// Create a new cell with the reuse identifier of our prototype cell
// as our custom table cell class
let cell = tableView.dequeueReusableCellWithIdentifier("myProtoCell") as! MyTableView
// Set the first row text label to the firstRowLabel data in our current array item
cell.user.text = user[indexPath.row]
// Set the second row text label to the secondRowLabel data in our current array item
cell.feedback.text = feedback[indexPath.row]
//cell.feedback.lineBreakMode = NSLineBreakMode.ByWordWrapping
//cell.feedback.numberOfLines = 2
// Set the datetime label to the datetime array
cell.dateTime.text = datetimes[indexPath.row]
// Return our new cell for display
return cell
}
func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
//println("You selected cell #\(indexPath.row)!")
// Get Cell Label text here and storing it to the variable
let indexPathVal: NSIndexPath = tableView.indexPathForSelectedRow!
//println("\(indexPathVal)")
let currentCell = tableView.cellForRowAtIndexPath(indexPathVal) as! MyTableView!;
//println("\(currentCell)")
//println("\(currentCell.iOSCellLbl?.text!)")
//Storing the data to a string from the selected cell
currentCell.user.text! = user[indexPath.row]
sendSelectedData = currentCell.user.text!
print(sendSelectedData)
//Now here I am performing the segue action after cell selection to the other view controller by using the segue Identifier Name
self.performSegueWithIdentifier("ShowFeedbackSegue", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
//Here i am checking the Segue and Saving the data to an array on the next view Controller also sending it to the next view COntroller
if segue.identifier == "ShowFeedbackSegue"{
//Creating an object of the second View controller
let controller = segue.destinationViewController as! FeedbackViewController
//Sending the data here
controller.SecondArray = sendSelectedData as String!
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
有什么想法吗？

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if let identifier = segue.identifier {
switch identifier{
case "ShowFeedbackSegue":
if let controller = segue.destinationViewcontroller as? FeedbackViewController {
controller.SecondArray = sendSelectedData as String! // SecondArray must be of //type string
}
default: break
}
}
}
