Swift Notes - 阿里云推送SDK配置

发表于 | 分类于 |

新项目里的消息推送功能，公司技术部开会讨论后决定让 极光，百度，aws都歇菜，取而代之的是尝试 使用阿里云推送SDK。所以今天就简单记录下调试过程。
新任务获得：使用阿里云推送SDK实现消息推送功能～

嗯常规套路先看官方文档 正面上我 。 嗯，很详细，很耐斯，很桥豆麻袋？库文件是OC写的？？？

坑爹啊，哥的项目都是swift写的啊。呃。。。。。。。。。好吧，也许加一个桥接就可以了。任务变更：桥接阿里云推送SDK（OC版）到Swift工程里，而后实现消息推送功能～

Ready to work

所谓工欲善其事，必先利其器。而且消息推送功能本身就是配置打过逻辑代码的功能，所以我们先要把准备工作做好。

Step.1 - 准备certificate文件

由于消息推送功能的实现，涉及到Apple的官方资源（感兴趣的同志们可以自行去谷歌APNS），所以需要准备特别的证书文件：development certificate x1， distribution certificate x1。然后这两个文件具体怎么获得呢，请 正面上我 。

Step.2 - 获得AppKey, AppSecret

这个appkey 和appsecret 是做啥的呢，嗯简单说就是这两个字串是阿里云用来标记你的app的，万一推错了就不好嘛，稍后我们会用点。那么问题又来了这两个字串那里搞呢？

支线任务获得：寻找NPC -公司的推送服务后台开发人员，交付 development certificate x1， distribution certificate x1后，获得 AppKey x1, AppSecret x1.

Step.3 - 配置App

配置App这个就简单了，打开你的项目代码。先把开发团队调到你们的公司

然后打开 Post Notifications 功能

Step.4 - 引入阿里云SDK

下载好压缩包打开，获得四个库文件，然后全部拖到你的项目工程里去。再然后么把 build settings 里的 Enable Bitcode 给关了。最后再转到 Build Phases 里面的 Link Binary With libraries， 加入四个依赖的系统库: libz.tbd，libresolv.tbd，CoreTelephony.framework，SystemConfiguration.framework 。

好啦，到此基本上所有的准备工作都做好了。接下来我们就可以开始写代码了。P.S. 其实上面的都可以在阿里云文档里看到，哥只是拿来凑字的～～

Core Work

Step.1 - 桥接

先建立一个 Header File，命名为 YourProjectName-Bridging-Header.h 。

然后呢去到 Build Setting里，找到 Objective-C Bridging Header 填入刚才的文件名

最后在刚才的桥接文件里，引入阿里云推送的库#import <CloudPushSDK/CloudPushSDK.h>, 这样就可以用SDK里的方法了。

Step.2 - 配置推送

先在APP启动时调用配置方法。

let aliyunpush_AppSecret = "8085ed1d1fc7739e9e058d2ad7fbb881"
let aliyunpush_messageNoti = "CCPDidReceiveMessageNotification"

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
        // Override point for customization after application launch.
        
        //init aliyun Push SDK
        initCloudPush(application: application)
        
        //feedback to aliyun server
        CloudPushSDK.handleLaunching(launchOptions)
        
        return true

    }

       let body : NSString = NSString(data: message.title, encoding: String.Encoding.utf8.rawValue)!
       print("Received Message title: \(title), content:\(body)")
   }
   
   //Observer & Handle remote Notifications - Foreground Mode
   func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
       print("REceive one notification.")
       
       //retreive APNS content
       
       let aps_dic : NSDictionary = userInfo["aps"] as! NSDictionary
       
       //content
       let content = aps_dic.value(forKey: "alert")
       
       //barge num
       let badge = (aps_dic.value(forKey: "badge") as AnyObject).integerValue
       
       //sound
       let sound = aps_dic.value(forKey: "sound")
       
       //extras
       let extras = aps_dic.value(forKey: "Extras")
       
       print("content: \(content)\n, badge:\(badge)\n, sound :\(sound)\n, Extras: \(extras)")
       
       application.applicationIconBadgeNumber = 0
       
       CloudPushSDK.handleReceiveRemoteNotification(userInfo)
   }

最后运行程序，看到如下结果就可以去交任务啦。

完结，鼓掌，撒花～～
