[英]working with cell on tableview using swift 2
I am developing a app using Swift 2. In my app I am parsing JSON data to a table view. 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。 When I tap a cell it successfully moves to another view controller but I am unable to fetch the json data.
当我点击一个单元格时,它成功移动到另一个视图控制器,但是我无法获取json数据。
This is the code in my view controller: 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)
}
When tapping on the cell it helps to move to other view controller SecondController
当点击单元格时,它有助于移动到其他视图控制器
SecondController
In my SecondController
I have two UILabel
s. 在我的
SecondController
我有两个UILabel
。 In those labels I want to show data ie strbookdetail
and strdrop
在这些标签中,我想显示数据,即
strbookdetail
和strdrop
How can I pass a reference between the two view controllers? 如何在两个视图控制器之间传递引用?
It is easy to do using property
pass data: 使用
property
传递数据很容易做到:
In 2th vc
: 在2
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"]
}
In 1th vc
: 在1
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)
}
