我的prepareForSegue电话问题一直存在.每当我尝试segue到下一个视图控制器.它会在我将tripLikes传递给下一个视图控制器时出现错误并崩溃.

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if (segue.identifier == "toDetailScene") {


        //Hooking up places-holder values
        let viewController = segue.destinationViewController as! DetailViewController

        let cell = sender as! CustomPFTableViewCell


        viewController.tripName = cell.nameTextLabel.text!
        viewController.tripAuthor = cell.authorTextLabel.text!
        viewController.tripLikes = Int(cell.numLikes.text!)!
        viewController.tripDescrip = cell.descriptionHolder

    }
}

我们传递给的每个值都是目标视图控制器中的值.
