移動分享是一個很普遍常見的問題，其中針對國外的app經常用到的無非這兩個。

以下是解決方案。
1.我也極力推薦的一個方案，ShareSDK，這個是中國自己的一個第三方整合的分享模組，裡面的功能很強大，包括目前所有的客戶端的分享。只要在官網上下載sharesdk的包，然後閱讀相關的文件，依樣畫葫蘆就行了。把包匯入到工程裡面，注意路徑的配置，然後註冊facebook和twitter的APIkey，然後是在ShareSDK官網上註冊appKey進行繫結。最後是程式碼裡面
 1.1在appdelegate.m檔案裡面註冊
#pragma mark -- SSO授權本地初始化SDK
+ (void)initializePlatWithSSO
{
    [ShareSDK registerApp:@"ebc7ea75b14"];
    
    //twitter
    [ShareSDK connectTwitterWithConsumerKey:@"WhdXQJq8TVnNtU9eyoCxQ"
                             consumerSecret:@"YY1975oq70MGojGXKuTxbgINXSrikfMfQDhSLr04"
                                redirectUri:@"http://website.com/"];
    
    //facebook
    [ShareSDK connectFacebookWithAppKey:@"703090989701898"
                              appSecret:@"59186b061caf72a34c7e5860cb65b745"];
}

然後- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation
{
    return [ShareSDK handleOpenURL:url
                 sourceApplication:sourceApplication
                        annotation:annotation
                        wxDelegate:self];
    
}
在要使用的類裡面，引入標頭檔案。
- (void)shareBySimpleway:(ShareType)type andContent:(NSString *)shareContent
{
//    NSString *imagePath = [[NSBundle mainBundle] pathForResource:IMAGE_NAME ofType:IMAGE_EXT];
    id<ISSShareOptions> simpleShareOptions =
    [ShareSDK simpleShareOptionsWithTitle:RBTLocalizedString(@"25_setting_contentShare", @"內容分享")
                        shareViewDelegate:nil ];
    
    id obj = nil;
    if(self.musicType == ShareMusicByFacebook)
    {
        obj = [ShareSDK imageWithUrl:self.shareImgStr];
    }
    
    if (self.musicType == ShareMusicByTwitter || m_shareType == ShareTypeClient || m_shareType == ShareTypePlayList) {
        obj = nil;
    }
    
    id<ISSContent> publishContent = [ShareSDK content:shareContent defaultContent:@"Greetings!"
                                                image:obj
                                                title:@"ShareSDK"
                                                  url:@"http://www.sharesdk.cn"
                                          description:@"Music shared!"
                                            mediaType:SSPublishContentMediaTypeNews];
    
    [ShareSDK showShareViewWithType:type container:nil content:publishContent statusBarTips:YES authOptions:nil shareOptions:simpleShareOptions result:^(ShareType type, SSPublishContentState state, id<ISSStatusInfo> statusInfo, id<ICMErrorInfo> error, BOOL end) {
        if (error != nil)
        {
            FXTRACE(FXT_DEBUG_LVL, @"Share", @"errorcode:%d errorDes:%@", [error errorCode], [error errorDescription]);
            [Utils showToast:[error errorDescription]];
        }
    }];
}

基本完成了，ShareMusicByTwitter和facebook是自定義的，原版的是ShareTypeFacebook和ShareTypeTwitter.

方式2：webview的形式這種很簡單，
分享到facebook：
 self.musicShareStr = [NSString stringWithFormat:@"http://www.facebook.com/sharer.php?m2w&s=100&p[title]=%@&p[summary]=%@&p[url]=%@&p[images][0]=%@",self.shareName,@"",urlString,self.shareImgStr];
分享到twitter：
self.musicShareStr = [NSString stringWithFormat:@"https://twitter.com/intent/tweet?&text=%@&url=%@",self.smsContent,urlStr1];

這種形式記住要清除快取：參考

方式3：使用Facebook官方sdk分享
就是一般的方式了，有官方的sdk包，在plist檔案配置FacebookAppID和FacebookDisplayName，然後在appdelegate裡面配置
在didfinishload裡面加入    [FBAppEvents activateApp];
    [FBAppCall handleDidBecomeActive];
在- (void)applicationWillTerminate:(UIApplication *)application
{
    // FBSample logic
    // if the app is going away, we close the session object
    [FBSession.activeSession close];
}
在使用的類裡面配置：
    // Show the feed dialog
    [FBWebDialogs presentFeedDialogModallyWithSession:nil
                                           parameters:[self setFacebookShareContent]
                                              handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
     {
          if (error)
          {
              // An error occurred, we need to handle the error
              // See: https://developers.facebook.com/docs/ios/errors
              FXTRACE(FXT_ERROR_LVL, @"Share", @"Share to Facebook error:%@",
                      error.description);
              [Utils showToast:RBTLocalizedString(@"25_setting_share_failed", @"failed")];
          }
          else
          {
              if (result == FBWebDialogResultDialogNotCompleted)
              {
                  // User cancelled.
                  FXTRACE(FXT_INFO_LVL, @"Share", @"User cancel shareing");
              }
              else
              {
                  // Handle the publish feed callback
                  NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
                  if (![urlParams valueForKey:@"post_id"])
                  {
                      // User cancelled.
                      FXTRACE(FXT_INFO_LVL, @"Share", @"User cancel shareing");
                  } else {
                      // User clicked the Share button
                      FXTRACE(FXT_INFO_LVL, @"Share", @"Share success, story id:%@",
                              [urlParams valueForKey:@"post_id"]);
                      [Utils showToast:RBTLocalizedString(@"25_setting_share_success", @"success")];
                  }
              }
          }
    }];

- (NSMutableDictionary *)setFacebookShareContent
{
    ConfigManager *configMg = [ConfigManager sharedInstance];
    NSMutableDictionary *shareFacebookDic=nil;
    if ([self.titleS isEqualToString:NSLocalizedString(@"Share", @"")])
    {
        shareFacebookDic = [NSMutableDictionary dictionaryWithObjectsAndKeys:configMg.shareClientAppToFbTextStr, @"name",
                                             configMg.shareClientAppToFbUrlStr,@"link", nil];
    }
    else
    {
        shareFacebookDic = [NSMutableDictionary dictionaryWithObjectsAndKeys:configMg.shareClientAppTextStr, @"name", nil];
    }
    
    if (!shareFacebookDic)
    {
        shareFacebookDic =  [NSMutableDictionary dictionaryWithObjectsAndKeys:RBTLocalizedString(@"default_share_Social", @"ShareFacebook"), @"name", nil];
    }
    return shareFacebookDic;
}
要配置這個分享的dic。

基本就這三種方式。
