Answer 1

When uploading a video, set the type to "video" in the attachment and the corresponding content type, for example "video/mp4":
QBRequest.uploadFile(with: localVideoUrl, fileName: nameVideo, contentType: "video/mp4", isPublic: true,
successBlock: { (response: QBResponse, uploadedBlob: QBCBlob) -> Void in
let attachment = QBChatAttachment()
attachment.id = uploadedBlob.uid
attachment.name = uploadedBlob.name
attachment.type = "video"
attachment["size"] = "\(uploadedBlob.size)"
// send message with attachment
}, statusBlock: { (request : QBRequest?, status : QBRequestStatus?) -> Void in
let progress = CGFloat(Float(status.percentOfCompletion))
// show progress
}
}) { (response : QBResponse) -> Void in
//error handler
}
When you receive a message with attachment and attachment type is "video”, refer to this example:
let attachment = message.attachments?.first
if attachment.type == "video" {
QBRequest.downloadFile(withUID: attachment.id, successBlock: { (response: QBResponse, fileData: Data) in
let fileData = fileData as NSData
let fileName = ID + "_" + attachment.name
let filePath = NSTemporaryDirectory() + fileName
let fileURL = URL(fileURLWithPath: filePath)
if fileData.write(to: fileURL, atomically: true) == true {
//do what you need with the video - cache, save, play, etc.
} else {
print("failure write")
}
}, statusBlock: { (request: QBRequest, status: QBRequestStatus?) in
let progress = CGFloat(status.percentOfCompletion)
//show progress
}, errorBlock: { (response: QBResponse) in
//error handler
})
}
