齐桓公之ios app微信登录授权及分享对接

微信sdk的引入及相关导入你可以参考这里：齐桓公(小白)首次盲接iosapp及微信sdk及发包

这里我们仅讨论并完成wxsdk的登录授权和分享编码

首先创建类文件WechatManager.mm,和头文件WechatManager.h

怎么创建？点击file ---- new file ---- 选择objective-cfile ----- 一步步下去

微信的授权等相关操作可分为以下几步

1、向微信注册，片段代码如下

说明：

注释的startLogByLevel.... 及后面checkUniversalLinkReady......是微信提供的代码调试工具方法，启动可以从日志里查看问题出在什么地方
wxid是微信公众平台的appid，universalLink:@这里的url是registerUniversalUrl，https://域名/path 当然如果没有path则直接域名url即可

2、检查微信安装状态

+(int)doIsWXAppInstalled
{
  BOOL isInstalled = [WXApi isWXAppInstalled];
  BOOL isSepport = [WXApi isWXAppSupportApi];
  if (isInstalled == YES && isSepport == YES)
  {
    return 1;
  }
  else
  {
    return 0;
  }
}

3、登录授权

说明：这里由于是js回调过来的登录，所以用了JSBridge，

wxLoginCallBack方法是jsbridge回调给js的方法，jsbridge会在ios对接内购支付的时候详解

这里要重写wxapi.h 里的这个回调方法，登录结果返回会回调到这里

- (void)onResp:(BaseResp*)resp;

+ (void)weChatLogin
{
  if(![WeChatManger doIsWXAppInstalled])
  {
    [JSBridge wxLoginCallBack:-3 code:@"" tip:@"登陆失败！您未安装微信!"];
  }
  else
  {
    SendAuthReq* req = [[SendAuthReq alloc] init];
    req.scope = @"snsapi_message,snsapi_userinfo,snsapi_friend,snsapi_contact"; // @"post_timeline,sns"
    req.state = @"none";
    [WXApi sendReq:req completion:nil];
  }
}

接下来是返回，这里的返回兼容处理了分享

- (void) onResp:(BaseResp*)resp
{
    if([resp isKindOfClass:[SendAuthResp class]])
    {
        SendAuthResp *temp = (SendAuthResp*)resp;
        if (temp.errCode== 0 && temp.code && temp.code.length != 0)
        {
            [JSBridge wxLoginCallBack:1 code:temp.code tip:@"登录成功"];
        }
        else{
            [JSBridge wxLoginCallBack:0 code:@"" tip:@"登录失败!"];
        }
    }
    else if([resp isKindOfClass:[SendMessageToWXResp class]])
    {
        switch (resp.errCode) {
            case WXSuccess:
                [JSBridge wxShareCallBack:1 tip:@"分享成功!"];
                break;
            case WXErrCodeAuthDeny:
                [JSBridge wxShareCallBack:-1 tip:@"分享已取消!"];
                break;
            default:
                [JSBridge wxShareCallBack:0 tip:@"分享失败!"];
                break;
        }
    }
}

3、分享

注意分享的几个参数 shareTitle 、shareType、shareDesc、shareImage等

+ (void)weChatShare:(NSString*) jsonParam
{
    NSData* data = [jsonParam dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary* json = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
    if (json == nil) return;
    NSString *shareType = json[@"shareType"];
    if(![WeChatManger doIsWXAppInstalled])
    {
        [JSBridge wxShareCallBack:-3 tip:@"未安装微信!"];
    }

        
   NSString *shareTitle = json[@"shareTitle"];NSString *shareIcon = json[@"shareIcon"];
   NSString *shareDesc = json[@"shareDesc"];NSString *shareLink = json[@"shareLink"];
   NSString *shareImageData = json[@"shareImage"];
   if( shareTitle == nil || shareTitle.length < 1 ||
       shareIcon == nil || shareIcon.length < 1 ||
       shareDesc == nil || shareDesc.length < 1 ||
       shareLink == nil || shareLink.length < 1 )
   {
       [JSBridge wxShareCallBack:-5 tip:@"分享信息缺失!"];
   }
   else
   {
       int nRet = 0;
       if( [shareType isEqualToString:@"text"] )nRet = 1;
       else if ( [shareType isEqualToString:@"webView"] )nRet = 2;
       else if ( [shareType isEqualToString:@"img"] )nRet = 3;
       switch (nRet)
       {
          case 1:
          {
              //初始化一个WXWebpageObject对象，填写url
              WXWebpageObject *webpageObject = [WXWebpageObject object];
              webpageObject.webpageUrl = shareLink;
              //用WXWebpageObject对象初始化一个WXMediaMessage对象，填写标题，描述
              WXMediaMessage *message = [WXMediaMessage message];
              message.title = shareTitle;
              message.description = shareDesc;
              NSDictionary *infoPlist = [[NSBundle mainBundle] infoDictionary];
              NSString *icon = [[infoPlist valueForKeyPath:@"CFBundleIcons.CFBundlePrimaryIcon.CFBundleIconFiles"] lastObject];
              UIImage * shareImage = [UIImage imageNamed:icon];
              [message setThumbImage:shareImage];
              message.mediaObject = webpageObject;
              SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];
              req.bText = NO;
              req.message = message;
              req.scene = WXSceneSession;
              [WXApi sendReq:req completion:nil];
              break;
          }
          case 2:
          {
              break;
          }
           case 3:
          {
              //UIImage *image = [[ViewController GetIOSViewController] getScreenShot];
              NSArray *array = [shareImageData componentsSeparatedByString:@","];
              NSData *ImageData = [[NSData alloc] initWithBase64EncodedString:array[1] options:NSDataBase64DecodingIgnoreUnknownCharacters];
              UIImage *image = [UIImage imageWithData:ImageData];
              // 下面就是组装要分享到微信的内容
              WXMediaMessage *message=[WXMediaMessage message];
              [message setThumbImage:image];
              WXImageObject *imageObject=[WXImageObject object];
              imageObject.imageData=UIImagePNGRepresentation(image);
              message.mediaObject=imageObject;

              SendMessageToWXReq *req=[[SendMessageToWXReq alloc]init];
              req.bText=NO;
              req.message=message;
              req.scene=WXSceneSession;
              [WXApi sendReq:req completion:nil];
              break;
          }
          default:{
              [JSBridge wxShareCallBack:-6 tip:@"不支持的分享类型！"];
              break;
          }
       }
       
   }
}

至此，微信的ios客户端对接完成，接下来就是掉登录分享的H5这边，H5这边通过jsbridge直接掉wxlogin方法，在回调方法里处理相关的逻辑，这里和web对接微信没啥区别，不过一个是引入js文件，一个是掉ios oc方法而已，代码片段如下

static doLogin() {
        Native.callWithBack(function (msg) {
            log("doLogin WXdoAuth code is :", msg["code"]);
            LoginHelperWXNative.onGetCode(msg["code"]);
            this.tag = 0;
        }, "wxLogin",'');
        this.tag = 1;
    }

微信sdk的ios对接一版情况下从github上可以搬过来用，都是对接相关的部分，如果H5对接过或者公众号小程序对接过，对流程很熟悉的话，基本就没什么问题了。

天将降大任于斯人也，必先苦其心志，劳其筋骨，饿其体肤....对齐桓公来说确实如此，微信sdk对接遇到的问题总结如下：

1、sdk库的导入相当棘手，建议参照官网一步一步来

2、登录授权的universal url配置一定要在访问【域名+apple-app-site-association】一定要能下载这个文件，否则配置失败，微信授权会报----universal Link校验不通过的错误

3、分享的时候分享连接一定要提供正确，这里会报一些分享的错误，没有关系有报错就好解决

最后说一句：砖石之所以能成砖石是因为他经过了千百万年的磨练一切事物皆如此倘不经历练何以知其真？何以享其乐？以此而已！
