iOS雲存儲：CloudKit 基本使用教程 增刪改查(Swift)

1、從iOS8開始，蘋果爲開發者提供了ClouKit，能夠把咱們的應用程序和用戶數據存儲在iCloud上，用於代替後臺服務器，開發移動代碼便可。

2、設置

（1）須要一個開發者帳號，而且設置一個bundle id 包含 iCloud功能

（2）設置xcode：

 

 

 

（3）設置模擬器，setting-iCloud 登陸帳號（能夠是非開發者帳號）

3、控制器增刪改查 Swift 代碼：

import UIKit
import CloudKit

//建立一條記錄的ID並指定一個惟一的名字，
let  artworkRecordID = CKRecordID.init(recordName: "Cats")
//        //建立一個記錄對象
let artworkRecord = CKRecord.init(recordType: "CatsTest", recordID:artworkRecordID)
//一、建立一個容器（使用默認容器）
let myContainer = CKContainer.defaultContainer()
//二、建立數據庫
let publicDatabase = myContainer.publicCloudDatabase

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        //添加數據
        artworkRecord["job"] = "iOS開發2"
        artworkRecord["name"] = "聶小波2"
        artworkRecord["address"] = "上海2"
        
        self.fetchRecordData()
        
    }
    
     func creatRecord() {
        //將記錄保存在數據庫
        publicDatabase.saveRecord(artworkRecord) { (artworkRecord, error) in
            if (error != nil) {
                print("creatRecord failure！")
            } else {
                print("creatRecord success！")
            }
        }

    }

    
    func fetchRecordData() {
        //在代碼中獲取咱們保存好的內容
        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("查詢信息：" ,"job:",job ,"names:", names ,"address:" , address)
            }
            
        }

    }
    
    func unpdateData() {
        //修改數據
        artworkRecord["name"] = "聶小波3"
        //將記錄保存在數據庫
        publicDatabase.saveRecord(artworkRecord) { (artworkRecord, error) in
            if (error != nil) {
                print("unpdateData failure！")
            } else {
                print("unpdateData success！")
            }
        }
    }

    func deleteRecordData() {
        //將記錄保存在數據庫
        publicDatabase.deleteRecordWithID(artworkRecordID) { (artworkRecord, error) in
            if (error != nil) {
                print("deleteRecord failure！")
            } else {
                print("deleteRecord success！")
            }
        }
    }

}

4、查看實時數據

進入蘋果開發者iCloud數據庫網頁地址：https://icloud.developer.apple.com/dashboard/ 登陸開發者帳號
