I am trying to set up a table view from a Parse database. Each cell should contain several pieces of data about one object (coded in Parse as what and where). When tapped, it should transition to a new page showing all available data about that object (including username, and when).
Here's my code for the table view:
import UIKit
import Parse
import ParseUI
class TableView: PFQueryTableViewController {
override init(style: UITableViewStyle, className: String!) {
super.init(style: style, className: className)
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
// Configure the PFQueryTableView
self.parseClassName = "ItemRequest"
self.textKey = "what"
self.pullToRefreshEnabled = true
self.paginationEnabled = false
}
override func queryForTable() -> PFQuery {
var query = PFQuery(className: "ItemRequest")
query.orderByAscending("what")
return query
}
//override func tableView(tableView: UITableView, cellForRowAtIndexPath
indexPath: NSIndexPath) -> UITableViewCell
override func tableView(tableView: UITableView, cellForRowAtIndexPath
indexPath: NSIndexPath, object: PFObject?) -> PFTableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("Cell") as! PFTableViewCell!
if cell == nil {
cell = PFTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
}
// Extract values from the PFObject to display in the table cell
if let what = object?["what"] as? String {
cell?.textLabel?.text = what
}
if let `where` = object?["`where`"] as? String {
cell?.detailTextLabel?.text = `where`
}
return cell
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath:
NSIndexPath) {
self.performSegueWithIdentifier("showDetails", sender: tableView)
}
var detailScene = segue.destinationViewController as! DetailViewController
if let indexPath = self.tableView.indexPathForSelectedRow() {
let row = Int(indexPath.row)
detailScene.currentObject = (objects?[row] as! PFObject)
}
}
}
And the code for the detail view:
import UIKit
import Parse
class DetailViewController: TableView {
var currentObject : PFObject?
@IBOutlet var whatis: UILabel!
@IBOutlet var whereis: UILabel!
@IBOutlet var whenis: UILabel!
@IBOutlet var whois: UILabel!
@IBOutlet var priceis: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
if let object = currentObject {
whatis.text = (object["what"] as! String)
whereis.text = (object["`where`"] as! String)
priceis.text = (object["price"] as! String)
whenis.text=(object["when"] as! String)
}
}
// Do any additional setup after loading the view.
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
When I run, the table shows only the "what" data points, and nothing else. When I try to select a row, it does not segue to the next screen (and I did segue set up in the storyboard). No error appears. Any help would be greatly appreciated- new to Swift and programming in general!
Update: tried the code suggested below and got a Thread1 Signal Sigabrt error. Error log below:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "uB8-vY-KsT-view-Ky8-TR-c7F" nib but didn't get a UITableView.'
