我一直在尝试在单元格中打印在我的PFQuery
中调用的viewWillAppear
,但是我从以下行中得到了错误:
cell?.textLabel?.text = message as NSString as String
这是tableView
cellForRowAtIndexPath
的代码:override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cellId: NSString = "cell"
var cell: UITableViewCell? = tableView.dequeueReusableCellWithIdentifier(cellId as String) as? UITableViewCell
if (cell == nil) {
cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: cellId as String)
}
let message = myMessagesArray![indexPath.row] as! PFObject
cell?.textLabel?.text = message as NSString as String
return cell!
}
这是
PFQuery
: var query = PFUser.query()
query!.orderByAscending("Messages")
query!.findObjectsInBackgroundWithBlock {
(objects: [AnyObject]?, error: NSError?) -> Void in
if error == nil {
println("Successfully retrieved \(objects!.count) messages.")
self.myMessagesArray = objects
self.tableView?.reloadData()
} else {
println(error!.localizedDescription)
}
}
最佳答案
使用此代码:
let message = myMessagesArray[indexPath!.row] as! PFObject
cell.textLabel?.text = message.objectForKey("Messages") as? String
关于ios - Swift-'PFObject无法转换为NSString',我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/31529586/
