Send files in chat

Users can transfer files in chat during the session.

Zoom deletes files sent via in-session chat when the session ends.

Enable send files via in-session chat in your Video SDK account portal settings and configure the following settings.

• Only allow specified file types - Select to allow only specific file types and enter the file extensions in the text box, separated by commas.
• Maximum file size - Select to limit the file size to 2048 MB.

Check if the file transfer feature is enabled.

let ret = ZMVideoSDK.shared().getSessionInfo().isFileTransferEnabled()

BOOL ret =  [[[ZMVideoSDK sharedVideoSDK] getSessionInfo] isFileTransferEnabled];

Get the list of allowed file types that you can transfer.

let ret = ZMVideoSDK.shared().getSessionInfo().getTransferFileTypeWhiteList()

NSString *ret =  [[[ZMVideoSDK sharedVideoSDK] getSessionInfo] getTransferFileTypeWhiteList];

Get the maximum file size to transfer.

let ret = ZMVideoSDK.shared().getSessionInfo().getMaxTransferFileSize()

unsigned long long  ret =  [[[ZMVideoSDK sharedVideoSDK] getSessionInfo] getMaxTransferFileSize];

Send files to all users in the current session.

let ret = ZMVideoSDK.shared().getSessionInfo().transferFile(filePath: String)

ZMVideoSDKErrors ret =  [[[ZMVideoSDK sharedVideoSDK] getSessionInfo] transferFile:self.filePathTextF.stringValue];

Send files to a certain user in the session.

// Locate the user that you would like to send the file to.
let receiver: ZMVideoSDKUser
// Send file directly.
let ret = receiver.transferFile(filePath: String)

ZMVideoSDKErrors ret =  [_receiverUser transferFile:self.filePathTextF.stringValue];

Cancel sending files.

// getCurrentSendFileObj is a user-defined method, to retrieve the sending file.
let sendFile: ZMVideoSDKSendFile = getCurrentSendFileObj()
let ret = sendFile.cancelSend()

ZMVideoSDKSendFile *send = [self getCurrentSendFileObj]; // getCurrentSendFileObj is a user-defined method, to retrieve the sending file.
ZMVideoSDKErrors ret =  [send cancelSend];

Start receiving files.

// getCurrentReceiveFileObj is a user-defined method, to retrieve the receiving file.
let receiveFile: ZMVideoSDKReceiveFile = getCurrentReceiveFileObj()
let fileDomain = FileManager.default.urls(for: .downloadsDirectory, in: .userDomainMask).map(\.path).last
let filePath = "<File path to receive>"
let downloadFilePath = "\(fileDomain)/\(filePath.count > 0 ? filePath : receiveFile.fileName)"
if (receiveFile) {
  let ret = receiveFile.startReceive(downloadFilePath)
  }

ZMVideoSDKReceiveFile *receive = [self getCurrentReceiveFileObj]; //getCurrentReceiveFileObj is a user-defined method, to retrieve the receiving  file.
NSString *fileDomain = [NSSearchPathForDirectoriesInDomains(NSDownloadsDirectory, NSUserDomainMask, YES).lastObject copy];
NSString *filePath = @"<File path to receive>";
NSString *downloadFilePath = [NSString stringWithFormat:@"%@/%@",fileDomain,filePath.length>0?filePath:receive.fileName];
if (receive) {
  ZMVideoSDKErrors ret =  [receive startReceive:downloadFilePath];
  } else {
    NSLog(@"receive is null");
  }

Cancel receiving files.

// getCurrentReceiveFileObj is a user-defined method, to retrieve the receiving file.
let receiveFile: ZMVideoSDKReceiveFile = getCurrentReceiveFileObj()
if (receiveFile) {
  let ret = receiveFile.cancelReceive()
  }

ZMVideoSDKReceiveFile *receive = [self getCurrentReceiveFileObj]; // getCurrentReceiveFileObj is a user-defined method, to retrieve the receiving  file.
  if (receive) {
    ZMVideoSDKErrors ret =  [receive cancelReceive];
  } else {
    NSLog(@"receive is null");
  }

File transfer callbacks

Be sure that you have set up a delegate for callback events to receive file transfer callbacks.

Get notified when you transfer a file.

func onSendFile(_ sendFile: ZMVideoSDKSendFile!, status: ZMVideoSDKFileTransferStatus) {
  // Get the transfer status of the file and the file content here.
  }

- (void)onSendFile:(ZMVideoSDKSendFile *)sendFile status:(ZMVideoSDKFileTransferStatus)status
{
  // Get the transfer status of the file and the file content here.
}

Get notified when you receive a file from other users.

func onReceiveFile(_ receiveFile: ZMVideoSDKReceiveFile!, status: ZMVideoSDKFileTransferStatus) {
  // Get the transfer status of the file and the file content here.
  }

-(void)onReceiveFile:(ZMVideoSDKReceiveFile *)receiveFile status:(ZMVideoSDKFileTransferStatus)status
{
  // Get the transfer status of the file and the file content here.
}
