集成CC视频sdk时关于离线下载在iOS 12闪退的问题

在iOS 12中苹果不允许对下载的resumeData进行修改编译,目前已经进行了修改,如果遇到这个问题可以自行修改也可以下载最新的demo或者联系研发人员!

#define IOS12 [[UIDevice currentDevice].systemVersion floatValue]>=12?YES:NO

 [vc.downloadTask cancelByProducingResumeData:^(NSData * _Nullable resumeData) {
            NSMutableDictionary *plist = [[FileManager sharedInstance]plist];

        if (IOS12) {
            if (resumeData && dicItem) {
            [dicItem setObject:resumeData forKey:@"dataString"];
            [plist setObject:dicItem forKey:vc.downLoadUrl];
            [[FileManager sharedInstance]saveplist:plist];
            
            if(vc.downloadType == DOWNLOAD_LOADING) {
               
                vc.downloadTask = [vc.session downloadTaskWithResumeData:resumeData];
                // 继续下载
                [vc.downloadTask resume];
