[英]How can I put cell data into a cell class instead of VC class?, iOS, Swift
[英]iOS How to send cell data to another VC use parse Swift
点击单元格时,如何将数据从表视图单元格发送到另一个VC。
我的从数据库获取数据的代码:
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! cellRequestsTVC
let good = data[indexPath.row]
name = good["username"] as! String
cell.userNameLable.text = "@\(name)"
area = good["place"] as! String
cell.areaLable.text = "\(area)"
cell.descriptionLable.text = good["description"] as? String
cell.priorityLable.text = "Priority " + ((good["priority"] as? Int)?.description)!
let imageProblems = good["image"] as? PFFile
imageProblems?.getDataInBackground{ (imageData, error)in
if imageData != nil {
let image = UIImage(data: imageData!)
cell.problemImage.image = image
}
}
return cell
}
工作正常。 但是现在我的目标是从另一个VC中的单元打开数据。 例:
您必须实现UITableViewDelegate
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let good = data[indexPath.row]
// Here you can either perform a segue or push view controller to UINavigationController
//Push View controller
let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let vc : DetailViewController = storyBoard.instantiateViewController(withIdentifier: "DetailViewController") as! DetailViewController
vc.sharedData = data // here you pass data
self.navigationController?.pushViewController(vc, animated: true)
}
在DetailViewController
创建具有所需类型的数据对象
var sharedData : [String : Any]! // Take optional variable if object can be nil & here assuming data contains object of type [String : Any]
