1. 准备工作

1.去各大平台注册appId，同时记得在工程里配置URL types。
2.下载ShareSDK，顺便要把它的适配文档看一看哦。

2.搭建工程

1.APP启动时注册ShareSDK

[ShareSDK registerApp:kShareSDKKey
          activePlatforms:@[
                            @(SSDKPlatformTypeSinaWeibo),
                            @(SSDKPlatformTypeWechat),
                            @(SSDKPlatformTypeQQ)
                            ]
                 onImport:^(SSDKPlatformType platformType) {
                     
                     switch (platformType)
                     {
                         case SSDKPlatformTypeWechat:
                             [ShareSDKConnector connectWeChat:[WXApi class] delegate:self];
                             break;
                         case SSDKPlatformTypeQQ:
                             [ShareSDKConnector connectQQ:[QQApiInterface class]
                                        tencentOAuthClass:[TencentOAuth class]];
                             break;
                         case SSDKPlatformTypeSinaWeibo:
                             [ShareSDKConnector connectWeibo:[WeiboSDK class]];
                             break;
                         default:
                             break;
                     }
                 }
          onConfiguration:^(SSDKPlatformType platformType, NSMutableDictionary *appInfo) {
              
              switch (platformType)
              {
                  case SSDKPlatformTypeSinaWeibo:
                      //设置新浪微博应用信息,其中authType设置为使用SSO＋Web形式授权
                      [appInfo SSDKSetupSinaWeiboByAppKey:kSinaAppKey
                                                appSecret:kSinaAppSecret
                                              redirectUri:kSinaAppRedirectUrl
                                                 authType:SSDKAuthTypeBoth];
                      break;
                  case SSDKPlatformTypeWechat:
                      [appInfo SSDKSetupWeChatByAppId:kWexinAppKey
                                            appSecret:kWexinAppSecret];
                      break;
                  case SSDKPlatformTypeQQ:
                      [appInfo SSDKSetupQQByAppId:kQQAppKey
                                           appKey:kQQAppSecret
                                         authType:SSDKAuthTypeBoth];
                      break;
                  default:
                      break;
              }
          }];

2.自定义UI下分享
先自定义一个shareModel，方便塞数据。

@interface ShareSDKObject : NSObject

@property (nonatomic, strong) NSString *shareUrl;
@property (nonatomic, strong) NSString *shareContent;
@property (nonatomic, strong) NSString *shareTitle;
@property (nonatomic, strong) NSArray *imageArray;  //数组对象可以为UIImage 或 NSString(图片地址)
@property (nonatomic, assign) SSDKContentType contentType;

+ (instancetype)shareObjectWithShareUrl:(NSString *)shareUrl shareContent:(NSString *)shareContent shareTitle:(NSString *)shareTitle imageArray:(NSArray *)imageArray;

- (NSMutableDictionary *)getShareParams;

@end

然后用自定义UI点击某个平台后到这里分享，注意showShareEditor是有文字编辑框的，此方法在<ShareSDKUI/ShareSDKUI.h>这个头文件中，若需要一键分享看下一段代码。

- (void)shareWithObject:(ShareSDKObject *)shareObject
           shareSuccess:(void(^)(SSDKPlatformType platform))success
            shareFailed:(void(^)(NSError *error))failed
            shareCancel:(void(^)(void))cancel {
    if (shareObject) {
        ShareView *shareView = [[ShareView alloc] init];
        [shareView performSelector:@selector(showWithAnimationInView:) withObject:nil afterDelay:0.1];
        [shareView setShareButtonClickBlock:^(SSDKPlatformType shareType) {
            if (shareType == SSDKPlatformTypeSinaWeibo) {
                shareObject.shareContent = [shareObject.shareContent stringByAppendingString:shareObject.shareUrl];
            }
            
            [ShareSDK showShareEditor:shareType otherPlatformTypes:nil shareParams:[shareObject getShareParams] onShareStateChanged:^(SSDKResponseState state, SSDKPlatformType platformType, NSDictionary *userData, SSDKContentEntity *contentEntity, NSError *error, BOOL end) {
                switch (state) {
                    case SSDKResponseStateSuccess:
                    {
                        if (success) {
                            success(platformType);
                        }
                        break;
                    }
                    case SSDKResponseStateFail:
                    {
                        if (failed) {
                            failed(error);
                        }
                        break;
                    }
                    case SSDKResponseStateCancel:
                    {
                        if (cancel) {
                            cancel();
                        }
                        break;
                    }
                    default:
                        break;
                }
            }];

        }];
    }
}

接着是实现没有文字编辑框的一键分享，ShareSDK share的方法在ShareSDK.h中，用这个就可以直接跳平台。同时在<ShareSDKExtension/SSEShareHelper.h>中有一个名为oneKeyShare的方法，然并卵的是用它时，它会报错说不支持微信等平台。

- (void)oneKeyShareWithType:(SSDKPlatformType) shareType
              shareObject:(ShareSDKObject *)shareObject
             shareSuccess:(void(^)(SSDKPlatformType platform))success
              shareFailed:(void(^)(NSError *error))failed
              shareCancel:(void(^)(void))cancel {
    
    [ShareSDK share:shareType parameters:[shareObject getShareParams] onStateChanged:^(SSDKResponseState state, NSDictionary *userData, SSDKContentEntity *contentEntity, NSError *error) {
        switch (state) {
            case SSDKResponseStateSuccess:
            {
                if (success) {
                    success(shareType);
                }
                break;
            }
            case SSDKResponseStateFail:
            {
                if (failed) {
                    failed(error);
                }
                break;
            }
            case SSDKResponseStateCancel:
            {
                if (cancel) {
                    cancel();
                }
                break;
            }
            default:
                break;
        }
    }];
}

以上就快速开发出分享功能，是不是很简单
