我已經更新了我的應用程序到Xcode 7並轉換爲swift2我已經清除了所有錯誤，但是現在在運行應用程序時它剛剛看到啓動屏幕後崩潰。從下面這行代碼是綠色（：斷點1.4線程1）：強調Swift 2崩潰選項
var cellNumber:Int! = 1
我真的不知道是什麼原因造成的問題。它我的第一個應用程序請請原諒我的編碼奇怪的方式：
ViewOne.swift
import Foundation
import UIKit
class ViewOne : UITableViewController {
override internal func viewDidLoad() {
super.viewDidLoad()
}
var cellNumber:Int! = 1
//var cellNumber = 1
@IBAction func Cell2Pressed(sender: UIButton) {
cellNumber = 2
}
@IBAction func Cell3Pressed(sender: UIButton) {
cellNumber = 3
}
@IBAction func Cell4Pressed(sender: UIButton) {
cellNumber = 4
}
@IBAction func Cell5Pressed(sender: UIButton) {
cellNumber = 5
}
@IBAction func Cell6Pressed(sender: UIButton) {
cellNumber = 6
}
@IBAction func Cell7Pressed(sender: UIButton) {
cellNumber = 7
}
@IBAction func Cell8Pressed(sender: UIButton) {
cellNumber = 8
}
@IBAction func Cell9Pressed(sender: UIButton) {
cellNumber = 9
}
override internal func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
`// @IBOutlet weak var Cell1Pressed: UITableViewCell!`
override internal func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
let DestViewControler : ViewController = segue.destinationViewController as! ViewController
// var Dest2ViewControler : RadioPlayer = segue.destinationViewController as! RadioPlayer
DestViewControler.trackNumber = cellNumber!
// Dest2ViewControler.trackNumber = cellNumber
}
}
