我正在使用Swift 2开发一个应用程序。在我的应用程序中,我正在将JSON数据解析为表视图。当我点击一个单元格时,它成功移动到另一个视图控制器,但我无法获取json数据。
这是我的视图控制器中的代码:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath){
var cell = self.TableView.dequeueReusableCellWithIdentifier("Cell",forIndexPath: indexPath) as! CustomTableCell
let strbookdetail : NSString=arrDict[indexPath.row] .valueForKey("booking_detail") as! NSString
let strdrop : NSString=arrDict[indexPath.row] .valueForKey("drop_address") as! NSString
cell.Bookdetail.text=strbookdetail as String
cell.Dropaddress.text=strdrop as String
return cell as CustomTableCell
}
//It helps to parse JSON data to table view.
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
TableView.deselectRowAtIndexPath(indexPath, animated: true)
let tripcontroller = self.storyboard?.instantiateViewControllerWithIdentifier("UpcomingController") as! Secondcontroller
navigationController?.pushViewController(tripcontroller, animated: true)
}
点击单元格时,有助于移动到其他视图控制器SecondController
在我SecondController
我有两个UILabel
。在这些标签中,我想显示数据,strbookdetail
和strdrop
如何在两个视图控制器之间传递引用?
答案 0 :(得分:0)
使用property
传递数据很容易做到:
在第2个vc
:
var dataFromBeforeVC:[String:String] = [String:String]()
override func viewDidLoad() {
super.viewDidLoad()
initData ()
}
func initData() {
// set data strbookdetail and strdrop to labelOne & labelTwo
labelOne.text = dataFromBeforeVC["strdrop"]
labelTwo.text = dataFromBeforeVC["strbookdetail"]
}
在第1个vc
:
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
TableView.deselectRowAtIndexPath(indexPath, animated: true)
let tripcontroller = self.storyboard?.instantiateViewControllerWithIdentifier("UpcomingController") as! Secondcontroller
let cell:UITableViewCell = tableView.cellForRow(at: indexPath as IndexPath)!
let strbookdetail : NSString=arrDict[indexPath.row] .valueForKey("booking_detail") as! NSString
let strdrop : NSString=arrDict[indexPath.row] .valueForKey("drop_address") as! NSString
tripcontroller.dataFromBeforeVC = [
"strdrop":strbookdetail,
"strdrop":strbookdetail
]
self.navigationController?.pushViewController(tripcontroller, animated: true)
}
