从CloudKit记录中选择creationDate [英] Select creationDate from CloudKit record

问题描述

我正在尝试用标题和副标题填充一个单元格。记录中带有字段的标题和带有CreationDate的详细信息。

I'm trying to fill a cell with title and subtitle. Title with the field and detail with the CreationDate from the record.

我正在尝试以下操作，但没有成员'ObjectForKey'

I am trying the following but I am getting a no member 'ObjectForKey'

var objects = CKRecord

var objects = CKRecord

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let reuseIdentifier = "Cell"
    var cell:UITableViewCell? = tableView.dequeueReusableCellWithIdentifier(reuseIdentifier) as UITableViewCell?
    if (cell != nil) {
        cell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: reuseIdentifier)
    }

    let object = objects[indexPath.row]
    cell!.textLabel!.text = object.objectForKey("Notes") as? String
    cell!.detailTextLabel?.text = object.creationDate.objectForKey("Notes") as? String
    return cell!
}

推荐答案

错误来自此行：

cell!.detailTextLabel?.text = object.creationDate.objectForKey("Notes") as? String

由于某种原因，您试图从记录的创建日期获取 Notes键（即是 NSDate 。

For some reason you are trying to get the "Notes" key from the record's creation date (which is an NSDate.

只需获取 creationDate 作为 NSDate 。然后使用 NSDateFormatter 将日期格式化为可分配给 detailTextLabel.text 。

Just get the creationDate as an NSDate. Then use an NSDateFormatter to format the date into a string you can assign to the detailTextLabel.text.
