shareSDK:外部分享调用的接口
shareServiceManager：内部底层逻辑的实现者

注册

注册三方分享的AppKey。

Appdelegate方法中配置分享key

在app delegate

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
    //注册微博： 
    [WeiboSDK registerApp:APPKEY];
    //注册微信：
    [WXApi registerApp:APPKEY];
    //注册QQ: 
    TencentOAuth *oAuth = [[TencentOAuth alloc] initWithAppId:[keydic objectForKey:SHARE_KEY] andDelegate:self];
    oAuth.accessToken = [userDefaults objectForKey:@"TencentAccessToken"];
    oAuth.expirationDate = [userDefaults objectForKey:@"TencentExpireDate"];
    oAuth.openId = [userDefaults objectForKey:@"TencentOpenID"];
}

中先注册各个分享渠道的key

分享需要用到的参数

请注意各个分享渠道的SDK的参数说明，例如：微博title不能超过140个汉字（280个字节），微信缩略图大小最大为32k......，否则会导致无法跳转对应App或者分享失败

所需要的数据有:

1）微信微博等的分享标题和分享文案
2）分享用到的标题旁边的缩略图（微信需要压缩到32k以下，QQ控件300k以下）
3）分享用到的原图图片和使用UIImageJPEGRepresentation(UIImage,CGFloat)压缩之后的NSData
4）分享渠道拼参，NSDictionary @{@“shareChannelTitle”：@“新浪微博”，@“SHARETYE”:@“ShareTypeSinaWeibo”};

拼接参数，调用对外接口shareSDK，弹出分享浮层


- (void)showShareViewWithShareDict:(NSDictionary *)shareDic{
    //分享标题，内容，链接，图片
    NSString *shareTitle   = [shareDic objectForKey:@"shareTitle"];
    NSString *shareContent = [shareDic objectForKey:@"shareContent"];
    NSString *shareURL     = [shareDic objectForKey:@"shareURL"];
    UIImage  *shareIMG     = [shareDic objectForKey:@"shareIMG"];
    if (!shareIMG||shareIMG == nil) {
        shareIMG = [UIImage imageNamed:@"分享默认图"];
    }
    if (shareURL.length == 0) {
        shareURL = self.URLString;
    }
    
    //分享的具体内容model
    SouFunShareDataModel *dataModel = [[SouFunShareDataModel alloc]init];
    dataModel.onlyText = NO;
    dataModel.shareResource = @"热门活动";
    
    //分享的链接地址
    dataModel.webURL = shareURL;
    //微信（QQ)
    dataModel.weChatTitle = shareTitle;
    dataModel.weChatDescription = shareContent;
    //微信朋友圈
    dataModel.weChatFriendTitle = shareContent;
    //QQ空间
    dataModel.QZoneTitle = shareTitle;
    dataModel.QzoneDescription = shareContent;
    //腾讯(新浪)微博
    dataModel.blogDescription = [NSString stringWithFormat:@"%@%@", shareContent, shareURL];//长度小于280字节
    //分享的图片
    dataModel.image = shareIMG;
    dataModel.orignalImageData = UIImageJPEGRepresentation(dataModel.image, 1.0f); //原图
    //压缩图片
    dataModel.thumbImage = [self compressImage:shareIMG];    //需要压缩到32K后的
    dataModel.imageData  = UIImageJPEGRepresentation(dataModel.thumbImage, 1.0f); //需要压缩后的，具体大小不知道
    // 短信分享内容
    dataModel.SMSDescription = [NSString stringWithFormat:@"%@  %@", shareContent, shareURL];
    
    //分享渠道UI数据拼参
    NSDictionary *sinaBlog = [[NSDictionary alloc] initWithObjectsAndKeys:@"新浪微博",SHARE_ICON_TILTE,ShareTypeSinaWeibo,SHARE_TYPE,nil];
    NSDictionary *weiChat  = [[NSDictionary alloc] initWithObjectsAndKeys:@"微信",SHARE_ICON_TILTE,ShareTypeWeixiSession,SHARE_TYPE,nil];
    NSDictionary *message  = [[NSDictionary alloc] initWithObjectsAndKeys:@"短信",SHARE_ICON_TILTE,ShareTypeSMS,SHARE_TYPE ,nil];
    NSDictionary *urlCopy  = [[NSDictionary alloc] initWithObjectsAndKeys:@"复制链接",SHARE_ICON_TILTE,ShareTypeCopy,SHARE_TYPE, nil];
    NSDictionary *QQZone   = [[NSDictionary alloc] initWithObjectsAndKeys:@"QQ空间",SHARE_ICON_TILTE,ShareTypeQQSpace,SHARE_TYPE, nil];
    NSDictionary *weiChatFriendGroup =[[NSDictionary alloc] initWithObjectsAndKeys:@"朋友圈",SHARE_ICON_TILTE,ShareTypeWeixiTimeline,SHARE_TYPE, nil];
    //添加分享渠道到数组中
    NSMutableArray *shareChannelArr =[[NSMutableArray alloc] initWithObjects:sinaBlog,weiChat,weiChatFriendGroup,message,urlCopy,QQZone, nil];
    
    SouFunShareSDK  *share=[SouFunShareSDK shareInstance];
    share.ShareChannels = shareChannelArr;
    share.cellSize = CGSizeMake(54, 54);
    //弹出分享浮层
    [share showShareViewWithShareDataModel:dataModel inViewInViewController:self];
}

点击某一个分享渠道，以微信为例详解底层逻辑：

点击微信后，相应代理方法，先判断是否安装了微信，未安装则提示未安装微信；如果安装了微信,将分享的参数传递给微信SDK

-(void)gotoViewControllerWithMark:(NSString *)shareType
}  
   if([shareType isEqualToString:ShareTypeWeixiSession] )
    {
        if(![WXApi isWXAppInstalled])
        {
            [ShareUIToastView showToastViewWithContent:@"您未安装微信，请先下载安装" andRect:KTOASTRECT andTime:3.0 andObject:_parentController];
            return;
        }
        [self weChatShare:_shareDataModel];

    }
    else if([shareType isEqualToString:ShareTypeWeixiTimeline])
    {
        if(![WXApi isWXAppInstalled])
        {
            [ShareUIToastView showToastViewWithContent:@"您未安装微信，请先下载安装" andRect:KTOASTRECT andTime:3.0 andObject:_parentController];
            return;
        }
        [self weChatFriendShare:_shareDataModel];
    }else  if ([UtilitiesReachability isAblityForNetwork]==NO){
        
        [ShareUIToastView showToastViewWithContent:@"网络连接失败，请稍后再试" andRect:KTOASTRECT andTime:2.0 andObject:_parentController];
    }     
 }

//微信好友分享
-(void)weChatShare:(SouFunShareDataModel *)shareDataModel
{
    _shareDataModel.currentShareType = @"WXSceneSession";
    if(shareDataModel.onlyText)
    {
        SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];
        req.bText = YES;
        req.text = shareDataModel.weChatDescription;
        req.scene = WXSceneSession;
        [WXApi sendReq:req];
    }
    else
    {
        WXMediaMessage *message = [WXMediaMessage message];
        message.title = shareDataModel.weChatTitle;
        message.description = shareDataModel.weChatDescription;
        [message setThumbImage:shareDataModel.thumbImage];
        
        WXWebpageObject *ext = [WXWebpageObject object];
        ext.webpageUrl = shareDataModel.webURL;
        
        message.mediaObject = ext;
        
        SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];
        req.bText = NO;
        req.message = message;
        req.scene = WXSceneSession;
        
        [WXApi sendReq:req];
    }
}
//微信朋友圈分享
-(void)weChatFriendShare:(SouFunShareDataModel *)shareDataModel
{
    _shareDataModel.currentShareType = @"WXSceneTimeLine";
    if(shareDataModel.onlyText)
    {
        SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];
        req.bText = YES;
        req.text = shareDataModel.weChaFriendtDescription;
        req.scene = WXSceneTimeline;
        [WXApi sendReq:req];
    }
    else
    {
        WXMediaMessage *message = [WXMediaMessage message];
        message.title = shareDataModel.weChatFriendTitle;
        message.description = shareDataModel.weChaFriendtDescription;
        [message setThumbImage:shareDataModel.thumbImage];
        
        WXWebpageObject *ext = [WXWebpageObject object];
        ext.webpageUrl = shareDataModel.webURL;
        
        message.mediaObject = ext;
        
        SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];
        req.bText = NO;
        req.message = message;
        req.scene = WXSceneTimeline;
        
        [WXApi sendReq:req];
    }
}

微信API发起跳转请求后：[WXApi sendReq:req]，得在appdelegate方法中通过WXApi 处理跳转

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    //delegate用于处理分享结果的回调
    return [WXApi handleOpenURL:url delegate:self];
}

在代理方法实现分享结果逻辑处理

-(void) onResp:(id)resp
{
    //微信好友，朋友圈分享
    if([resp isKindOfClass:[SendMessageToWXResp class]])
    {
        NSString *resultMsg = nil;
        int respondStatus = [resp errCode];
        
        if(respondStatus == 0)
        {
            resultMsg = @"分享成功";
        }
        else
        {
            resultMsg = @"分享失败，可以再试试~";
        }
        //提示分享结果
        [ShareUIToastView showToastViewWithContent:resultMsg andRect:KTOASTRECT andTime:3.0 andObject:_parentController];
    }
    //QQ好友，QQ空间分享
    else if([resp isKindOfClass:[SendMessageToQQResp class]])
    {
        NSString *resultMsg = nil;
        int respondStatus = [[resp result]  intValue];
        
        if(respondStatus == 0)
        {
            resultMsg = @"分享成功";
        }
        else
        {
            resultMsg = @"分享失败，可以再试试~";
        }
        
        [ShareUIToastView showToastViewWithContent:resultMsg andRect:KTOASTRECT andTime:3.0 andObject:_parentController];
    }
}

至此，整个分享流程就结束了，还需要注意的是iOS9需要将你要在外部调用的URL scheme列为白名单，才可以完成跳转跳转第三方应用，否则会报错

canOpenURL: failed **for** URL : "mqzone://qqapp" - error: "This app is not allowed to query for scheme mqzone"

需要在info.plist的设置LSApplicationQueriesSchemes属性为数组，添加所用到的所有scheme
