iOS云存储：CloudKit 基本使用教程 增删改查(Swift)

1、从iOS8开始，苹果为开发者提供了ClouKit，能够把咱们的应用程序和用户数据存储在iCloud上，用于代替后台服务器，开发移动代码便可。

2、设置

（1）须要一个开发者帐号，而且设置一个bundle id 包含 iCloud功能

（2）设置xcode：

 

 

 

（3）设置模拟器，setting-iCloud 登陆帐号（能够是非开发者帐号）

3、控制器增删改查 Swift 代码：

import UIKit
import CloudKit

//建立一条记录的ID并指定一个惟一的名字，
let  artworkRecordID = CKRecordID.init(recordName: "Cats")
//        //建立一个记录对象
let artworkRecord = CKRecord.init(recordType: "CatsTest", recordID:artworkRecordID)
//一、建立一个容器（使用默认容器）
let myContainer = CKContainer.defaultContainer()
//二、建立数据库
let publicDatabase = myContainer.publicCloudDatabase

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        //添加数据
        artworkRecord["job"] = "iOS开发2"
        artworkRecord["name"] = "聂小波2"
        artworkRecord["address"] = "上海2"
        
        self.fetchRecordData()
        
    }
    
     func creatRecord() {
        //将记录保存在数据库
        publicDatabase.saveRecord(artworkRecord) { (artworkRecord, error) in
            if (error != nil) {
                print("creatRecord failure！")
            } else {
                print("creatRecord success！")
            }
        }

    }

    
    func fetchRecordData() {
        //在代码中获取咱们保存好的内容
        publicDatabase.fetchRecordWithID(artworkRecordID) { (artworkRecord, error) in
            if (error != nil) {
                print("selectData failure！")
            } else {
                print("selectData success！")
                let job = artworkRecord!["job"];
                let names = artworkRecord!["name"];
                let address = artworkRecord!["address"];
                
                print("查询信息：" ,"job:",job ,"names:", names ,"address:" , address)
            }
            
        }

    }
    
    func unpdateData() {
        //修改数据
        artworkRecord["name"] = "聂小波3"
        //将记录保存在数据库
        publicDatabase.saveRecord(artworkRecord) { (artworkRecord, error) in
            if (error != nil) {
                print("unpdateData failure！")
            } else {
                print("unpdateData success！")
            }
        }
    }

    func deleteRecordData() {
        //将记录保存在数据库
        publicDatabase.deleteRecordWithID(artworkRecordID) { (artworkRecord, error) in
            if (error != nil) {
                print("deleteRecord failure！")
            } else {
                print("deleteRecord success！")
            }
        }
    }

}

4、查看实时数据

进入苹果开发者iCloud数据库网页地址：https://icloud.developer.apple.com/dashboard/ 登陆开发者帐号
