CloudKit:按创建日期对查询结果进行排序 [英] CloudKit: Order query results by creation date

问题描述

从CloudKit加载项目时，我想按创建日期排序结果.我相信现在它是按记录的第一个属性排序的.

When loading items from CloudKit I would like to order the results by creation date. I believe now it's sorting by the first property of the record.

func loadItems() {
    let predicate = NSPredicate(value: true)
    let query = CKQuery(recordType: "Items", predicate: predicate)
    db.performQuery(query, inZoneWithID: nil) { (results, error) -> Void in
        if error != nil {
            println(error.localizedDescription)
        }

        dispatch_async(dispatch_get_main_queue()) { () -> Void in
            items = results as [CKRecord]
            self.tableView.reloadData()
            println("items: \(items)")
        }
    }
}

推荐答案

这就是我想要的:

query.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
