Swift 项目引入 LeanCloud

发表于 2018-09-08   |   分类于 Swift 课程


  • 创建一个 Single View Application
  • 在项目根目录创建一个 Podfile
  • 在其中加入如下代码,这里的 ins-test 是项目名,然后执行 pod install
target "ins-test" do
  pod "LeanCloud", "~> 11.0.1"
  • 打开项目名.xcworkspace文件
  • 在项目的 AppDelegate.swift 中加入 LeanCloud 引入的代码引入代码


Appdelegate.swift 文件中加入如下代码


然后运行应用即可在 LeanCloud 控制台看到创建的数据




use_frameworks! # LeanCloud Swift SDK can only be integrated as framework.

target "ins-test" do
  pod "LeanCloud", "~> 11.0.1"

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        LeanCloud.initialize(applicationID: "3B5SllOK7TgK5xGQTpxXARPH-gzGzoHsz", applicationKey: "9DB0NF42z5uNUlzb6WbeovDE")
        let post = LCObject(className: "TestObject")
        post.set("words", value: "Hello World!")
        post.save { result in

            case LCBooleanResult.success: print("Success")
            case LCBooleanResult.failure: print("Failure")
        return true

    func applicationWillResignActive(_ application: UIApplication) {
        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
        // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.

    func applicationDidEnterBackground(_ application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.

    func applicationWillEnterForeground(_ application: UIApplication) {
        // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.

    func applicationDidBecomeActive(_ application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

    func applicationWillTerminate(_ application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
