Quickblox: how find out whether the user is online? - quickblox

Question

Is there any way to find out whether the Quickblox user is online?
I'm using Quickblox iOS SDK.

Answer 1

There are 2 ways:
Using REST API - here is a guide http://quickblox.com/developers/SimpleSample-users-ios#Online.5COffline_status
Using Chat contact list http://quickblox.com/developers/SimpleSample-chat_users-ios#Contact_list

Answer 2

Swift 5 :
To get opponent user's Online Status And accurate Last Seen we have to add both users in each others contactList by using addUserToContactListRequest() API.
User A sends a request to become "friends" with user B. User B accepts the friend request. And now user A and B appear in each other's roster.
Step 1:
Check whether opponent user is already added in contacts or not
let isAvailable = QBChat.instance.contactList?.contacts?.filter {(contacts) -> Bool in
// self.dialog.recipientID is an opponent user's ID
return contacts.userID == self.dialog.recipientID ? true : false
}
If available in contacts check online status, if not available then send request to add in contacts.
if isAvailable!.count > 0 {
if isAvailable![0].isOnline {
//print("User Is Online")
} else {
//print("User Is Offline")
//Check Last Seen
self.fetchLastSeen(userId: self.dialog.recipientID)
}
} else {
QBChat.instance.addUser(toContactListRequest: UInt(self.dialog!.recipientID)) { (err) in
print("\(err)")
}
}
Step 2 :
implement QBChatDelegate methods.
Add contacts request
// This method will get called whenever you will receive any new add contact request
func chatDidReceiveContactAddRequest(fromUser userID: UInt) {
//Confirm add to contact list request.
QBChat.instance.confirmAddContactRequest(userID) { (error) in
}
}
Following method called in case when user's from contact list online status has been changed.
func chatDidReceiveContactItemActivity(_ userID: UInt, isOnline: Bool, status: String?) {
if userID == self.dialog.recipientID {
if isOnline {
print("User Is Online")
} else {
//print("User Is Offline")
//Check Last Seen
fetchLastSeen(userId: NSInteger(userID))
}
}
}
Step 3:
fetch the last seen of an user using this lastActivityForUser()
func fetchLastSeen(userId: NSInteger){
QBChat.instance.lastActivityForUser(withID: UInt(userId)) { (timeStamp, err) in
print(timeStamp)
// here we get total seconds, since how long user was inactive
// minus the seconds from current time
if err == nil {
let updatedTime = Calendar.current.date(byAdding: .second, value: -Int(timeStamp), to: Date())
guard let dateSent = updatedTime else {
return
}
var lastSeenStr = ""
if (Calendar.current.isDateInToday(updatedTime!)){
lastSeenStr = "Today"
} else if (Calendar.current.isDateInYesterday(updatedTime!)){
lastSeenStr = "Yesterday"
} else {
let dateFormat = DateFormatter()
dateFormat.dateFormat = "d-MMM"
lastSeenStr = dateFormat.string(from: updatedTime!)
}
let text = messageTimeDateFormatter.string(from: dateSent)
print("\(lastSeenStr + " " + text)") // e.g. 11-Sep 11:44 AM
}
}
}
