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。

一、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

二、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];}

三、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;    }}

四、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
