iOS 自定义常见第三方分享

平时经常会遇到做第三分享的需求，相信大家好多都使用的集成的分享平台shareSDK、友盟分享等。他们其实是对各种第三方平台进行了二次封装，有时需求只要求做其中一种平台的分享的时候其实像shareSDK这种集成环境就有些显得比较冗余了，因为他集成了很多的平台，用户可自定义程度不高，使得自己的程序会变得很臃肿，今天就把自己的干货拿出来，来讲一讲自定义的第三方分享。
下面主要讲一下目前应用比较广的，QQ、微信、微博的分享。

集成SDK

首先要集成你要做分享平台的SDK，和相应环境的配置，这些配置在我之前的博客中都有所提及，我就不在这里再次叙述了
微博SDK的集成：微博SDK集成
QQ SDK集成：QQ SDK集成
微信SDK集成：微信SDK集成
注意在集成SDK后需要在Appdelegate中进行注册

微博的分享

+ (void)weiboShareLinkWithUrl:(NSString *)url title:(NSString *)title description:(NSString *)description andPicUrl:(NSString *)picUrl  
{  
    NSLog(@"调用了微博");  
      
    AppDelegate *myDelegate =(AppDelegate*)[[UIApplication sharedApplication] delegate];  
      
    WBAuthorizeRequest *authRequest = [WBAuthorizeRequest request];  
    authRequest.redirectURI = @"这里填写你申请微博应用时的回调网址";  
    authRequest.scope = @"all";  
      
    WBMessageObject *message = [WBMessageObject message];  
      
    //设置分享的标题  
    message.text = title;  
      
    WBWebpageObject *webpage = [WBWebpageObject object];  
    webpage.objectID = @"identifier1";  
    webpage.title = title;  
    webpage.description = description;  
      
    //设置分享出去显示的图片  
    if (picUrl.length == 0 || picUrl == nil)  
    {  
        webpage.thumbnailData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"icon_share" ofType:@"png"]];  
    }  
    else  
    {  
        webpage.thumbnailData = [NSData dataWithContentsOfURL:[NSURL URLWithString:picUrl]];  
    }  
    webpage.webpageUrl = url;  
    message.mediaObject = webpage;  
      
    WBSendMessageToWeiboRequest *request = [WBSendMessageToWeiboRequest requestWithMessage:message authInfo:authRequest access_token:myDelegate.wbtoken];  
    request.userInfo = @{@"ShareMessageFrom": @"SendMessageToWeiboViewController",  
                         @"Other_Info_1": [NSNumber numberWithInt:123],  
                         @"Other_Info_2": @[@"obj1", @"obj2"],  
                         @"Other_Info_3": @{@"key1": @"obj1", @"key2": @"obj2"}};  
      
    //调用此方法进行分享  
    [WeiboSDK sendRequest:request];  
}

QQ的分享

QQ的分享分为分享给QQ好友和分享到QQ空间
这里首先定义一个枚举类型来区分是哪一种分享
在分享工具类的头文件里：

typedef enum : NSUInteger {  
    QQShare_Friends,  
    QQShare_Qzone,  
} QQShare_Type;

然后实现分享方法：

+ (void)qqShareLinkWithScene:(QQShare_Type)scene url:(NSString *)url title:(NSString *)title andDescription:(NSString *)description  
{  
    NSURL *shareUrl = [NSURL URLWithString:url];  
      
    NSLog(@"调用了QQ");  
      
    NSString *picUrl = @"这里填写你要分享出图的图片链接";  
    NSURL *imageUrl = [NSURL URLWithString:picUrl];  
   
    //通过QQAPIObject来创建将要分享的对象     
    QQApiObject *newsObj = [QQApiNewsObject objectWithURL:shareUrl title:title description:description previewImageURL:imageUrl targetContentType:QQApiURLTargetTypeNews];  
    //设置分享Req对象  
    SendMessageToQQReq *req = [SendMessageToQQReq reqWithContent:newsObj];  
      
    switch (scene)  
    {  
            //分享给QQ好友  
        case QQShare_Friends:  
        {  
            [QQApiInterface sendReq:req];  
            break;  
        }  
            //分享给QQ空间  
        case QQShare_Qzone:  
        {  
            [QQApiInterface SendReqToQZone:req];  
            break;  
        }  
        default:  
            break;  
    }  
}

微信的分享

微信的分享也同QQ一样，是分为分享微信好友和分享微信朋友圈，这里只要引入微信的头文件就可以了，微信官方SDK已经声明了所需要用的枚举了，无需我们再进行设置了。
用以下代码实现分享：

+ (void)wechatShareLinkWithScene:(int)scene url:(NSString *)url title:(NSString *)title andDescription:(NSString *)description  
{  
    //封装mediaMessage对象  
    WXMediaMessage *message = [WXMediaMessage message];  
      
    //设置微信分享的title  
    [message setTitle:title];  
    //设置分享描述内容  
    [message setDescription:description];  
    //设置分享所需图片  
    [message setThumbImage:[UIImage imageNamed:@"icon_share"]];  
      
    NSLog(@"调用了微信");  
      
    //封装WXWebpageObject对象  
    WXWebpageObject *ext = [WXWebpageObject object];  
    ext.webpageUrl = url;  
      
    message.mediaObject = ext;  
      
    //发送请求  
    SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];  
    req.bText = NO;  
    req.message = message;  
    req.scene = scene;  
      
    [WXApi sendReq:req];  
}

这样就实现了简单的分享，一般的需求几乎都可以满足，是不是很简单。

总结下

首先集成你准备分享平台的SDK，然后进行Appdelegate的注册，然后实现分享，这里需要注意下，微信和微博分享的图片是传本地图片，QQ是要传图片的链接，(这里要吐槽下，不理解传链接有什么用)。

既然分享就要分享的彻底点，下面po出博主自己封装的分享工具类，如有不足之处还请大家多提意见😏

调用示例：

- (void)shareViewButtonClick:(CustomShareType)shareType  
{  
    NSLog(@"%s",__func__);  
    NSLog(@"%lu",(unsigned long)shareType);  
      
    switch (shareType)  
    {  
        case ShareType_Weixin_Friend:  
        {  
            [JFShareTool wechatShareLinkWithScene:WXSceneSession url:url title:_shareTitle andDescription:_shareContent];  
            break;  
        }  
        case ShareType_Weixin_Circle:  
        {  
            [JFShareTool wechatShareLinkWithScene:WXSceneTimeline url:url title:_shareTitle andDescription:_shareContent];  
            break;  
        }  
        case ShareType_Weibo:  
        {  
            [JFShareTool weiboShareLinkWithUrl:url title:_shareTitle description:_shareContent andPicUrl:nil];  
            break;
