Quickblox iOS视频附件

我已将Quickblox iOS（Objc）库集成到我的聊天模块应用程序中。

作为 QBRequest TUploadFile 方法下的附件的图像是可能的。但我找不到任何有效的解决方案来制作同一请求下的视频附件。

我已经通过阅读Quickblog中的文件证实了这一点 - 在Quickblox聊天SDK下可以使用视频附件。

有没有人有任何工作解决方案来制作视频文件？

下面的代码用于在 QBRequest TUploadFile 下上传视频。

提前致谢！

- (void)uploadAndSendAttachmentMessage:(QBChatMessage*)message toDialog:(QBChatDialog*)dialog withChatService:(QMChatService*)chatService withAttachedVideo:(NSData*)videoData completion:(QBChatCompletionBlock)completion {
    [self changeMessageAttachmentStatus:QMMessageAttachmentStatusLoading forMessage:message];

    [QBRequest TUploadFile:videoData fileName:@"attachment video" contentType:@"video/mp4" isPublic:YES successBlock:^(QBResponse* response, QBCBlob* blob) {
        QBChatAttachment* attachment = [QBChatAttachment new];
        attachment.type = @"video";
        attachment.ID = blob.UID;
        attachment.url = [blob publicUrl];

        message.attachments = @[attachment];
        message.text = @"Attachment video";

        [self saveData:videoData chatAttachment:attachment error:nil];
        [self.attachmentsStorage setObject:videoData forKey:attachment.ID];

        [self changeMessageAttachmentStatus:QMMessageAttachmentStatusLoaded forMessage:message];

        [chatService sendMessage:message type:QMMessageTypeText toDialog:dialog saveToHistory:YES saveToStorage:YES completion:completion];
    } statusBlock:^(QBRequest* request, QBRequestStatus* status) {
        if ([self.delegate respondsToSelector:@selector(chatAttachmentService:didChangeUploadingProgress:forMessage:)]) {
            [self.delegate chatAttachmentService:self didChangeUploadingProgress:status.percentOfCompletion forMessage:message];
        }
    } errorBlock:^(QBResponse* response) {
        [self changeMessageAttachmentStatus:QMMessageAttachmentStatusNotLoaded forMessage:message];

        if (completion) {
            completion(response.error.error);
        }
    }];
}

您可以使用以下方法发送视频。

- (void)sendAttachmentMessage:(QBChatMessage *)attachmentMessage
                     toDialog:(QBChatDialog *)dialog
               withAttachment:(QBChatAttachment *)attachment
                   completion:(nullable QBChatCompletionBlock)completion

完整的代码如下所示

- (void)didPickAttachmentVideo:(NSURL *)video {

    QBChatMessage *message = [QBChatMessage new];
    message.senderID = self.senderID;
    message.dialogID = self.dialog.ID;
    message.dateSent = [NSDate date];



    __weak typeof(self)weakSelf = self;
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
        __typeof(weakSelf)strongSelf = weakSelf;

        QBChatAttachment *attachment = [QBChatAttachment videoAttachmentWithFileURL:video];

        // Sending attachment to the dialog.

        dispatch_async(dispatch_get_main_queue(), ^{

            [self.chatDataSource addMessage:message];

            [[ServicesManager instance].chatService sendAttachmentMessage:message
                                                                 toDialog:strongSelf.dialog
                                                           withAttachment:attachment
                                                               completion:^(NSError *error) {

                                                                   [strongSelf.attachmentCells removeObjectForKey:message.ID];
                                                                   NSString * myurl = attachment.remoteURL.absoluteString;
                                                                   if (error != nil) {
                                                                       [strongSelf.chatDataSource deleteMessage:message];
                                                                    //Show error alert

                                                                   }
                                                               }];
        });
    });
}
