Here's one that supports Storyboards, customizing the default cells, changes the row height and adds a sort to the generated query written in Swift. Doesn't include everything as listed above but should get some of you guys started.
import UIKit
import Parse
import ParseUI
class ShipmentListViewController: PFQueryTableViewController {
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
// The className to query on
self.parseClassName = "ClassName"
// The key of the PFObject to display in the label of the default cell style
self.textKey = "text"
// Uncomment the following line to specify the key of a PFFile on the PFObject to display in the imageView of the default cell style
self.imageKey = "image"
// Whether the built-in pull-to-refresh is enabled
self.pullToRefreshEnabled = true
// Whether the built-in pagination is enabled
self.paginationEnabled = true
// The number of objects to show per page
self.objectsPerPage = 25
}
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.rowHeight = 54.0
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func queryForTable() -> PFQuery {
let query = super.queryForTable()
query.orderByAscending("createdAt")
return query
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject?) -> PFTableViewCell? {
let cell = super.tableView(tableView, cellForRowAtIndexPath: indexPath, object: object)
// Configure the cell
cell?.imageView?.contentMode = .ScaleAspectFill
cell?.imageView?.clipsToBounds = true
cell?.accessoryType = .DisclosureIndicator
return cell
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
