我有一个表格视图,它从Firebase加载数据库信息,并且图像从我的硬编码目录/文件从Firebase存储中拉出。从Firebase填充数组传递UITableViewCell数据

我想要cell.videoID.text的值,以便我可以通过Segue将它传递给另一个viewcontroller。当单击单元格时,我似乎无法获取cell.videoID.text的值,并试图从此站点和其他站点以各种方式尝试。

public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 

    return vehicleList.count 
} 

public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 

    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! ViewControllerTableViewCell 
    let vehicle: VehicleModel 

    vehicle = vehicleList[indexPath.row] 


    cell.videoID.text = vehicle.id 
    cell.neworusedLabel.text = vehicle.neworused 
    cell.yearLabel.text = vehicle.year 
    cell.priceLabel.text = vehicle.price 
    cell.makeLabel.text = vehicle.make 
    cell.modelLabel.text = vehicle.model 
    cell.packageLabel.text = vehicle.package 
    cell.colorLabel.text = vehicle.color 

    // Get the image from storage container 

    let storage = Storage.storage().reference() 
    let imagePath = "tmpDir/tmpImage.png" 
    let tempImageRef = storage.child(imagePath) 
    tempImageRef.getData(maxSize: 1 * 600 * 600) { data, error in 
     if error == nil { 
      cell.lblView.image = UIImage(data: data!) 
     } else { 
      print(error?.localizedDescription) 
     } 
    } 

    return cell 
} 

var valueToPass:String! 

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { 

    // Get Cell Label 
    let indexPath = tableView.indexPathForSelectedRow! 
    let currentCell = tableView.cellForRow(at: indexPath)! as UITableViewCell 
    print("currentCell") 

    print("You selected cell #\(indexPath.row)!") 

// valueToPass = "Trying to get the videoID" 

    performSegue(withIdentifier: "detailSegue", sender: self) 
}

而你的'prepareForSegue'? –

在performSegue之前备份一行,这就是我卡住的地方。我无法在performSegue之前获得变量......所以prepareForSegue中的代码与此无关(但它适用于本项目中的其他10个vc)。 – user3534305

试试这个'valueToPass = vehicleList [indexPath.row] .id' –

我的回答是:valueToPass = vehicleList [indexPath.row] .ID

由于耿介以上的评论!
