ios - 类型 'UIViewController' 的值没有成员 'varView'

Question

请快帮忙

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    var DestVC = segue.destinationViewController as UIViewController

    var indexPath : NSIndexPath = self.tableView.indexPathForSelectedRow!

    DestVC.varView = indexPath.row // This is the error line

}

错误是

Value of type 'UIViewController' has no member 'varView'

Answer 1

用您的目标 View Controller 更改 UIViewController。例如，您的目标 View Controller 名称是 YourViewController并且还使用 if let 来安全解包

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if let DestVC = segue.destinationViewController as? YouViewController  {

var indexPath : NSIndexPath = self.tableView.indexPathForSelectedRow!

DestVC.varView = indexPath.row 

}
