swift开发之 -- 微信原生分享

swift集成微信原生分享，并没有用友盟的第三方sdk，直接对接的原生，相比较OC版的话，swift来说代码量很少，代码如下：

1，导入WechatOpenSDK，推荐使用cocoapods集成的话，非常便捷，具体操作流程就不多说了，可查看我的关于cocoapods的博客，如下图：

注：CD到当前项目路径，然后使用pod search WechatOpenSDK，可以查找最新版本；

      执行vim Podfile命令，按 i 键，进入编辑模式，在文件中加入 pod 'WechatOpenSDK'

      最后执行 pod install，或者 pod update，如需更新本地仓库执行 pod repo update命令

      按esc键，：wq，退出即可

 2，集成完后，需要创建桥接文件，然后配置下桥接文件的路径，可配置一个绝对路径：

 从工程的路径开始，前面使用$(SRCROOT)代替，这样的话，就不用每次变更项目路径就得配置桥接文件路径了。

3，添加白名单：

 如上图红框里面一样，添加“LSApplicationQueriesSchemes”，添加 wechat，weixin，weixinULAPI 

4，在桥接文件里面导入头文件

5，添加URL Types：

6，在AppDelegate文件里面，添加如下代码：

universal link，这个通用链接的话，可以参考微信官方文档，这里就不在详细叙述了：

7，回调方法，代码如下：

//iOS 9.0以前使用
    func application(_ application: UIApplication, handleOpen url : URL) -> Bool{
        let handleUrlStr = url.absoluteString
        if let handleUrl = URL(string: handleUrlStr) {
            return WXApi.handleOpen(handleUrl, delegate: self)
        }
        return false
    }
    
    //ios 9.0及以后推荐使用
    func application(_ app: UIApplication, open url: URL, options : [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool{
        let handleUrlStr = url.absoluteString
        if let handleUrl = URL(string: handleUrlStr) {
            return WXApi.handleOpen(handleUrl, delegate: self)
        }
        return false
    }
    
    //必须实现
    func application(_ application: UIApplication, open url: URL, sourceApplication:String?, annotation:Any) -> Bool{
        let handleUrlStr = url.absoluteString
        if let handleUrl = URL(string: handleUrlStr) {
            return WXApi.handleOpen(handleUrl, delegate: self)
        }
        return false
    }
    
    func application(_ application: UIApplication, continue userActivity: NSUserActivity,restorationHandler:@escaping([UIUserActivityRestoring]?) -> Void) -> Bool{
        return WXApi.handleOpenUniversalLink(userActivity, delegate: self)
    
    }

8，具体调用，代码如下：

声明一个枚举：

enum LDShareType {
    case Session, Timeline, Favorite/*会话, 朋友圈, 收藏*/
}

分享文本：

 func shareText(_ text: String, to scene: LDShareType) {
        
        let req = SendMessageToWXReq()
        req.text = text
        req.bText = true
        
        switch scene {
        case .Session:
            req.scene = Int32(WXSceneSession.rawValue)
        case .Timeline:
            req.scene = Int32(WXSceneTimeline.rawValue)
        case .Favorite:
            req.scene = Int32(WXSceneFavorite.rawValue)
        }
        
        WXApi.send(req)
    }

分享图片：

func shareImage(_ data: Data, thumbImage: UIImage, title: String, description: String, to scene: LDShareType) {
        
        let message = WXMediaMessage()
        message.setThumbImage(thumbImage)
        message.title = title
        message.description = description
        
        let obj = WXImageObject()
        obj.imageData = data
        message.mediaObject = obj
        
        let req = SendMessageToWXReq()
        req.bText = false
        req.message = message
        
        switch scene {
        case .Session:
            req.scene = Int32(WXSceneSession.rawValue)
        case .Timeline:
            req.scene = Int32(WXSceneTimeline.rawValue)
        case .Favorite:
            req.scene = Int32(WXSceneFavorite.rawValue)
        }
        
        WXApi.send(req)
    }

分享音乐：

func shareMusic(to scene: LDShareType) {
        let message = WXMediaMessage()
        message.title = "音乐标题"
        message.description = "音乐描述"
        message.setThumbImage(UIImage())
        
        let obj = WXMusicObject()
        obj.musicUrl = "音乐链接"
        obj.musicLowBandUrl = obj.musicUrl
        
        obj.musicDataUrl = "音乐数据链接地址"
        obj.musicLowBandDataUrl = obj.musicDataUrl
        message.mediaObject = obj
        
        let req = SendMessageToWXReq()
        req.bText = false
        req.message = message
        switch scene {
        case .Session:
            req.scene = Int32(WXSceneSession.rawValue)
        case .Timeline:
            req.scene = Int32(WXSceneTimeline.rawValue)
        case .Favorite:
            req.scene = Int32(WXSceneFavorite.rawValue)
        }
        
        WXApi.send(req)
    }

分享视频：

func shareVideo(to scene: LDShareType) {
        
        let message = WXMediaMessage()
        message.title = "视频标题"
        message.description = "视频描述"
        message.setThumbImage(UIImage())
        
        let obj = WXVideoObject()
        obj.videoUrl = "视频链接地址"
        obj.videoLowBandUrl = "低分辨率视频地址"
        
        let req = SendMessageToWXReq()
        req.bText = false
        req.message = message
        
        switch scene {
        case .Session:
            req.scene = Int32(WXSceneSession.rawValue)
        case .Timeline:
            req.scene = Int32(WXSceneTimeline.rawValue)
        case .Favorite:
            req.scene = Int32(WXSceneFavorite.rawValue)
        }
        
        WXApi.send(req)
    }

分享URL：

func shareURL(to scene: LDShareType) {
        
        let message = WXMediaMessage()
        message.title = "title"
        message.description = "description"
        message.setThumbImage(UIImage())
        
        let obj = WXWebpageObject()
        obj.webpageUrl = "http://www.baidu.com"
        message.mediaObject = obj
        
        let req = SendMessageToWXReq()
        req.bText = false
        req.message = message
        
        switch scene {
        case .Session:
            req.scene = Int32(WXSceneSession.rawValue)
        case .Timeline:
            req.scene = Int32(WXSceneTimeline.rawValue)
        case .Favorite:
            req.scene = Int32(WXSceneFavorite.rawValue)
        }
        
        WXApi.send(req)
    }

结果回调方法：

func onResp(_ resp: BaseResp!) {
        if resp is SendAuthResp {
            // 微信登录
           
        } else if resp is SendMessageToWXResp {
            let send = resp as? SendMessageToWXResp
            if let sm = send {
                if sm.errCode == 0 {
                    print("分享成功")
                } else {
                    print("分享失败")
                }
            }
        }
        
    }

以上代码亲测过，仅做记录，刚写swift代码，感谢下面简书两位博主的博客，微信的sdk写的也还行。
