使用自定义PFTableViewCell和PFQueryTableViewController显示多个更新标签时遇到问题。声明的第一个textKey或对象在运行后显示,但其他标签显示为空白。你现在也会注意到,日期也没有拉动,但我一次只能解决一个问题。我想我需要声明另一个textKey类,但已尝试添加到PFQueryTableViewController.h并启动但这不起作用。这是我的TableViewController:
import UIKit; import Parse
class UserRecordsTableViewController: PFQueryTableViewController {
// Initialise the PFQueryTable tableview
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 = "Event"
self.textKey = "category"
self.textKey = "duration"
self.pullToRefreshEnabled = true
self.paginationEnabled = false
}
// Define the query that will provide the data for the table view
override func queryForTable() -> PFQuery! {
var query = PFQuery(className: "event")
query.orderByAscending("category")
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 UserRecordsTableViewCell!
if cell == nil {
cell = UserRecordsTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
}
// Extract values from the PFObject to display in the table cell
cell.durationEventLabel.text = object["duration"] as? String
cell.dateEventLabel.text = object["category"] as? String
// Date for cell subtitle
/*var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"
let dateForText = object["createdAt"] as NSDate
cell.dateEventLabel.text = dateFormatter.stringFromDate(dateForText)*/
return cell
}
// 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].
/*var detailScene = segue.destinationViewController as YourDetailViewController
// Pass the selected object to the destination view controller.
if let indexPath = self.tableView.indexPathForSelectedRow() {
let row = Int(indexPath.row)
detailScene.currentObject = objects[row] as? PFObject
}*/
}
}
这是自定义单元格:
import UIKit
class UserRecordsTableViewCell: PFTableViewCell {
@IBOutlet weak var dateEventLabel: UILabel!
@IBOutlet weak var catEventLabel: UILabel!
@IBOutlet weak var durationEventLabel: UILabel!
}
以下是我的PFQueryTableViewController.h
的选择@property (nonatomic, strong) NSString *textKey;
答案 0 :(得分:0)
我已经决定了我想要的外观的最佳方法是使用parse框架提供的PFTableViewCell并且只显示两个项目。主要类别和日期为副标题。这与创建自定义单元格相反,后者适用于文本和图像标签,但不适用于两个文本键。 按照本教程进行操作非常棒:
