1、封装一个方法、传入外部控制的参数

- (void)presentSnsIconSheetViewWithShareText:(NSString *)shareText comicID:(NSString *)comicId objType:(NSString *)objType title:(NSString * )title cachedImage:(UIImage * )cachedImage shareUrl:(NSString * )shareUrlString currentVc:(id)viewcontroller successBlock:(void(^)())successBlock
{
    self.objuid = comicId;
    self.objType = objType;
    [UMSocialShareUIConfig shareInstance].sharePageGroupViewConfig.sharePageGroupViewPostionType = UMSocialSharePageGroupViewPositionType_Bottom;
    [UMSocialShareUIConfig shareInstance].shareTitleViewConfig.isShow = NO;
    [UMSocialShareUIConfig shareInstance].shareCancelControlConfig.isShow = NO;
    [UMSocialShareUIConfig shareInstance].sharePageScrollViewConfig.shareScrollViewPageItemStyleType = UMSocialPlatformItemViewBackgroudType_None;
     #ifdef UM_Swift
    [UMSocialSwiftInterface showShareMenuViewInWindowWithPlatformSelectionBlockWithSelectionBlock:^(UMSocialPlatformType platformType, NSDictionary* userInfo) {
     #else
        [UMSocialUIManager setPreDefinePlatforms:@[@(UMSocialPlatformType_Sina),@(UMSocialPlatformType_QQ),@(UMSocialPlatformType_Qzone),@(UMSocialPlatformType_WechatSession),@(UMSocialPlatformType_WechatTimeLine)]];
        [UMSocialUIManager showShareMenuViewInWindowWithPlatformSelectionBlock:^(UMSocialPlatformType platformType, NSDictionary *userInfo) {
     #endif
            //在回调里面获得点击的
            if (platformType == UMSocialPlatformType_Sina || platformType == UMSocialPlatformType_WechatSession ||
                platformType == UMSocialPlatformType_WechatTimeLine ||
                platformType == UMSocialPlatformType_QQ || platformType == UMSocialPlatformType_Qzone) {//qq，qq空间，微信，微信朋友圈,微博
                dispatch_async(dispatch_get_main_queue(), ^{
                    //创建分享消息对象
                    UMSocialMessageObject *messageObject = [UMSocialMessageObject messageObject];
                    
                    NSMutableString *urlString = [NSMutableString stringWithString:shareUrlString];
                    if ([urlString containsString:@"http://"]) {
                        [urlString insertString:@"s" atIndex:4];
                    }
                    //创建网页内容对象
                    UMShareWebpageObject *shareObject = [UMShareWebpageObject shareObjectWithTitle:title descr:shareText thumImage:cachedImage];
                    //设置网页地址
                    shareObject.webpageUrl = urlString;
                    //分享消息对象设置分享内容对象
                    messageObject.shareObject = shareObject;
                    //调用分享接口
                    [[UMSocialManager defaultManager] shareToPlatform:platformType messageObject:messageObject currentViewController:viewcontroller completion:^(id data, NSError *error) {
                        if (!error) {
                            successBlock();
                            //统计分享成功
                            UserActionResquest * resquest = [[UserActionResquest alloc]initWithObjType:objType optType:@"SHARE" objUid:comicId objPuid:nil];
                            [resquest sendRequestSuccessBlock:^(id baseModel){} requestFailBlock:^(KSError *error) {}finalBlock:^{}];
                        }
                    }];
                });
            }
        }];
    }

2、调用上面的分享方法

[[UMengShare uMengshareManager]presentSnsIconSheetViewWithShareText:shareStr comicID:self.detailModel.cartoondetailspuductsmodel.comicUid objType:@"comic" title:@"天唐动漫，超好看！" cachedImage:image shareUrl:url currentVc:self successBlock:^{
            [weakSelf.view makeToast:@"分享成功"];
        }];

返回首页

  let rootVc = ZMShopMainViewController()
    rootVc.selectedIndex = 0
    kWindow?.rootViewController = rootVc

返回具体的控制器

   let scanVc = navigationController?.childViewControllers[1]
    self.navigationController?.popToViewController(scanVc!, animated: true)

压缩图片

if ([format isEqualToString:@"png"]) {
        data = UIImagePNGRepresentation(image);
      } else if ([format isEqualToString:@"jpeg"]) {
        CGFloat quality = [RCTConvert CGFloat:options[@"quality"] ?: @1];
        data = UIImageJPEGRepresentation(image, quality);
      }
