我正在尝试从我的tableview中获取数据到视图控制器。到目前为止,我能够移动单元格中显示的数据,但出于某种原因,我无法使用该变量。
以下是已经有效的内容
//Prepare for Segue
destination.titleSegue = (cell?.textLabel?.text!)!
destination.priceSegue = (cell?.detailTextLabel?.text!)!
destination.imageSegue = (cell?.imageView?.image!)!
所有数据都会传输到第二个视图。
现在,我将向您展示我的cellForRowAtIndexPath
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = UITableViewCell(style: .Subtitle , reuseIdentifier: cellId)
cell.backgroundColor = UIColor.clearColor() //Makes colour of cells clear so we can see the background
cell.textLabel?.text = userList[indexPath.row].title //Shoes Name
cell.textLabel?.textColor = UIColor.whiteColor() //Sets text colour to white
cell.detailTextLabel?.text = "$\(userList[indexPath.row].price!)" //Displays price of shoes
cell.detailTextLabel?.textColor = UIColor.whiteColor() //Sets text colour to white
//LOOK HERE STACK OVERFLOW*******
let descriptionText = userList[indexPath.row].description
let URLString = self.userList[indexPath.row].listingImageURL //Finds URL of profile image
let URL = NSURL(string:URLString!)! //Converts URL Stirng to NSURL
cell.imageView?.frame = CGRectMake(10,10,100,100) //Sets frame size for images on tableview TODO
cell.imageView?.contentMode = .ScaleAspectFit //Sets image to aspect fill for image TODO
cell.imageView?.hnk_setImageFromURL(URL) //Displays image on table view from Haneke Framework
return cell
}
如果你回到我的prepare for segue
,我需要打电话来解析" descriptionText"来自CellForRowAtIndexPath
的变量以使数据移动到第二个视图控制器?
答案 0 :(得分:2)
let indexPath = tableView.indexPathForSelectedRow
let descriptionText = self.userList[indexPath.row].description
