我正在尝试将多个值保存到CloudKit(名称,用户名,点)。但是,当我保存它们时,它们分别保存在3个不同的行中,如下所示:
我想将Name,Username和Points字段组合成一行,以便我可以将它们一起加载。
以下是保存代码:
func saveToCloud(){
let newName = CKRecord(recordType: "LeaderboardInfo")
newName.setValue(firstName, forKey: "Name")
database.save(newName) { (record, error) in
guard record != nil else { return }
print("saved record")
}
let newUsername = CKRecord(recordType: "LeaderboardInfo")
newUsername.setValue(username, forKey: "Username")
database.save(newUsername) { (record, error) in
guard record != nil else { return }
print("saved record")
}
let pointsCount = CKRecord(recordType: "LeaderboardInfo")
pointsEarned = Int(arc4random_uniform(UInt32(50)))
pointsCount.setValue(pointsEarned, forKey: "Points")
database.save(pointsCount) { (record, error) in
guard record != nil else { return }
print("saved record")
}
}
有人可以演示如何将这些记录保存在一起而不是单独保存吗?
除此之外,我现在应该将它们分开加载... 加载代码:
func queryDatabase() {
// Name
let query = CKQuery(recordType: "LeaderboardInfo", predicate: NSPredicate(value: true))
database.perform(query, inZoneWith: nil) { (records, _) in
guard let records = records else { return }
let sortedRecords = records.sorted(by: { $0.creationDate! > $1.creationDate! })
self.names = sortedRecords
DispatchQueue.main.async {
// self.tableView.refreshControl?.endRefreshing()
self.tableView.reloadData()
}
}
// Username
let query2 = CKQuery(recordType: "LeaderboardInfo", predicate: NSPredicate(value: true))
database.perform(query2, inZoneWith: nil) { (records, _) in
guard let records = records else { return }
let sortedRecords = records.sorted(by: { $0.creationDate! > $1.creationDate! })
self.usernames = sortedRecords
DispatchQueue.main.async {
// self.tableView.refreshControl?.endRefreshing()
self.tableView.reloadData()
}
}
// Points
let query3 = CKQuery(recordType: "LeaderboardInfo", predicate: NSPredicate(value: true))
database.perform(query3, inZoneWith: nil) { (records, _) in
guard let records = records else { return }
let sortedRecords = records.sorted(by: { $0.creationDate! > $1.creationDate! })
self.points = sortedRecords
DispatchQueue.main.async {
// self.tableView.refreshControl?.endRefreshing()
self.tableView.reloadData()
}
}
}
我希望在保存和加载过程中将数据分组在一起。
P.S。如果它有助于任何人更好地理解,我试图制作一个包含所有用户的公共排行榜'名称或用户名及其要点。

您正在创建3个单独的记录,并在每个记录上设置一个字段,一个不同的字段。相反,只需创建1条记录并在其上设置所有3个字段。尝试这样的事情(我在SWIFT上没有真正的速度,所以你可能需要稍微使用语法)
func saveToCloud()
{
let newRecord = CKRecord(recordType: "LeaderboardInfo")
newRecord.setValue(firstName, forKey: "Name")
newRecord.setValue(username, forKey: "Username")
pointsEarned = Int(arc4random_uniform(UInt32(50)))
newRecord.setValue(pointsEarned, forKey: "Points")
database.save(newRecord) { (record, error) in
guard record != nil else { return }
print("saved record")
}
}
