iOS第三方SDK集成——快速集成微信、QQ、微博分享

一直觉得使用友盟SDK和ShareSDK来实现应用的分享功能是一种懒的表现。而系统自带分享SLComposeViewController又有很大的局限性。所以，自己构造分享界面和实现分享功能是一件必走之路。好在可以封装一下，便于快速集成。

Step1 各个平台创建应用

预先通知一下需要准备的资源，这样接下来进行会很快。

应用名称，比如：v2Ex
应用介绍
应用bundleID
应用appid
28x28，108x108，16x16，512x512，16x16， 80x80 120x120象素的图标
480x800象素的2张介绍图（QQ）
450x300象素的3张介绍图（新浪微博）

1. 登录微信开放平台，创建应用，得到APPKEY。

创建应用需要名称，简介，图片28x28，108x108 大小的png图片

2.登录QQ开放平台，创建应用。得到APPid

Snip20160627_1.png

Snip20160627_2.png

16x16 512x512

3.登录微博开放平台，创建应用。得到APPKEY

需要16x16 80x80 120x120象素图标，450x300象素的3张介绍图。

Step2 封装分享的实现逻辑

1.导入第三方SDK

导入之后，需要添加以下几个库才能正常运行

如果使用新浪微博分享的话需要再加入ImageIO.framework
还需要设置Other Linker Flags -ObjC。

2.封装分享内容

    ///分享的标题，非空
@property(nonatomic,copy)NSString *shareTitle;
    ///分享的内容，可为空
@property(nonatomic,copy)NSString *shareContent;
    ///分享的占位图片的url
@property(nonatomic,copy)NSString *shareThumbImageUrl;
    ///分享的占位图片data数据
@property(nonatomic,copy)NSData *shareThumbImageData;
    ///分享的点击跳转的链接
@property(nonatomic,copy)NSString *shareUrl;

3.封装分享实例(此处的分享只设定为分享一个链接，包括标题，内容，占位图和点击的URL)

- (BOOL)shareLinkToWeChatWithScene:(enum WXScene)scene shareModel:(HBShareModel *)shareModel
{
    if ([WXApi isWXAppInstalled]) {
        WXMediaMessage *mediaMessage = [WXMediaMessage message];
        mediaMessage.title = shareModel.shareTitle.length > 0 ? shareModel.shareTitle : @"标题";
        mediaMessage.description = shareModel.shareContent.length > 0 ? shareModel.shareContent : @"";
        WXWebpageObject *webPage = [WXWebpageObject object];
        webPage.webpageUrl = shareModel.shareUrl.length > 0 ? shareModel.shareUrl : @"";
        mediaMessage.mediaObject = webPage;
        
        if (shareModel.shareThumbImageData) {
            [mediaMessage setThumbData:shareModel.shareThumbImageData];
        }else if ( shareModel.shareThumbImageUrl) {
                //此处有一个隐患，url获取data是一个同步请求
           UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:shareModel.shareThumbImageUrl]]];
            [mediaMessage setThumbImage:image];

        }
            //随意设置，便于统计作用
        mediaMessage.mediaTagName   = @"WECHAT_TAG_SHARE";
        SendMessageToWXReq *request = [SendMessageToWXReq new];
        request.bText = NO;
        request.message = mediaMessage;
        request.scene = scene;
        
        return [WXApi sendReq:request];
        
    }else{
        [self handlerNotInstallAppWithTytpe:WeChatFriend];
        return NO;
    }
}
- (BOOL)shareLinkToQQWithScene:(NSInteger)scene shareModel:(HBShareModel *)shareModel
{
    if ([TencentOAuth iphoneQQInstalled]) {
        QQApiNewsObject *newsObject = nil;
        NSString *title       = shareModel.shareTitle.length > 0 ? shareModel.shareTitle : @"标题";
        NSString *description = shareModel.shareContent.length > 0 ? shareModel.shareContent : @"";
        NSString * str_url = shareModel.shareUrl.length > 0 ? shareModel.shareUrl : @"";
        NSURL  *url = [NSURL URLWithString:str_url];
        NSData *imageData = shareModel.shareThumbImageData;
        if (imageData) {
             newsObject = [QQApiNewsObject objectWithURL:url title:title description:description  previewImageData:imageData];
        }else{
            NSString *imageUrl = shareModel.shareUrl.length > 0?shareModel.shareUrl:@"";
            newsObject = [QQApiNewsObject objectWithURL:url title:title description:description previewImageURL:[NSURL URLWithString:imageUrl]];
        }
        
        SendMessageToQQReq* request  = [SendMessageToQQReq reqWithContent:newsObject];
        QQApiSendResultCode resultCode = 0;
            //1 为QQZOne 0 为QQ
        if (scene) {
             resultCode = [QQApiInterface SendReqToQZone:request];
        }else{
             resultCode = [QQApiInterface sendReq:request];
        }
        if (0 == resultCode) {
            return YES;
        }
        return NO;
    }else{
        [self handlerNotInstallAppWithTytpe:QQFriend];
        return NO;
    }

}
- (BOOL)shareLinkToWeiboWithShareModel:(HBShareModel *)shareModel {
    if ([WeiboSDK isWeiboAppInstalled]) {
        
        WBWebpageObject *webpage = [WBWebpageObject object];
        webpage.objectID = shareModel.shareUrl ;
        webpage.title = shareModel.shareTitle.length > 0 ? shareModel.shareTitle : @"标题";
        webpage.description =shareModel.shareContent.length > 0 ? shareModel.shareContent : @"";
        if (shareModel.shareThumbImageData) {
            webpage.thumbnailData = shareModel.shareThumbImageData;
        }else if (shareModel.shareThumbImageUrl) {
                //此处有一个隐患，url获取data是一个同步请求
            NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:shareModel.shareThumbImageUrl]];
             webpage.thumbnailData = data;
        }
        webpage.webpageUrl = shareModel.shareUrl;
        WBMessageObject *message = [WBMessageObject message];
        message.mediaObject = webpage;
        WBAuthorizeRequest *authRequest = [WBAuthorizeRequest request];
        WBSendMessageToWeiboRequest *request = [WBSendMessageToWeiboRequest requestWithMessage:message authInfo:authRequest access_token:nil];
        return [WeiboSDK sendRequest:request];
    }else {
        [self handlerNotInstallAppWithTytpe:WeiBo];
        return NO;
    }
    
    
}

4.创建URL Scheme，便于返回应用

微信的URL Scheme设置为：appkey
QQ的设置为：tencent+申请到的appID
微博的为：wb+appkey

5.构造个性化分享View

这一步仁者见仁，智者见智了，构造一个个性化十足的VIew，调用shareManager的相关方法即可。

6. plus iOS9相关

info.plist中除了要设置App Transport Security Settings 的Allow Arbitrary Loads为YES，还需要单独为应用跳转设置LSApplicationQueriesSchemes

LSApplicationQueriesSchemes

3. 问题描述

此处的分享没有处理回调。因为分享是把分享内容传递出去，不需要回传回内容回来，所以回调没有处理。下一篇，集成微信，QQ登录的文章会讨论如何处理回调。
微博的分享由于没有申请APPKey成功（审核还真严格），所以就没有测试成功。微信和QQ，亲测分享成功，且回调正常。
测试代码放在了这里。https://coding.net/u/HustBroventure/p/ThirdPartSDKIntegrate/git 原谅我没提交到GitHub。提交了一下午，文件太大，没提交成功。
