Trying to send and receive data in the GameCenter environment using the following methods:
func sendData(dictionaryWithData dictionary: Dictionary<String, Any>,toPeer targetPeers: [GKPlayer]) {
guard let match = self.match else { return }
do {
let dataToSend = try NSKeyedArchiver.archivedData(withRootObject: dictionary, requiringSecureCoding: false)
try match.send(dataToSend, to: targetPeers, dataMode: .reliable)
}
catch {
#if DEBUG
print("CONNECTION MANAGER SEND DATA ERROR")
#endif
}
}
public func match(_ theMatch: GKMatch,didReceive data: Data,forRecipient recipient: GKPlayer,fromRemotePlayer player: GKPlayer) {
if match != theMatch { return }
DispatchQueue.main.async {
do {
guard let message = NSDictionary.unsecureUnarchived(from: data) as? Dictionary<String, Any> else {return}
...
<CODE>
...
}
///Source: https://stackoverflow.com/questions/51487622/unarchive-array-with-nskeyedunarchiver-unarchivedobjectofclassfrom
static func unsecureUnarchived(from data: Data) -> Self? {
do {
let unarchiver = try NSKeyedUnarchiver(forReadingFrom: data)
unarchiver.requiresSecureCoding = false
let obj = unarchiver.decodeObject(of: self, forKey: NSKeyedArchiveRootObjectKey)
if let error = unarchiver.error {
print("Error:\(error)")
}
return obj
} catch {
print("Error:\(error)")
}
return nil
}
Everything works great until the data exceeds 87K (which, I understand, is the limit for exchanging data in GameCenter).
The data is not sent and gives the following error:
Async message[1FCA0D11-05DE-47D0-9714-983C8023F5C1] send error: FailedToSendData: , InternalError: reliable, maxPayloadSizeExceeded
Interesting enough, I do not have this problem when using MCSession, as follows, even if data exceeds 87K:
func sendData(dictionaryWithData dictionary: Dictionary<String, Any>, toPeer targetPeers: [MCPeerID]) {
do {
let dataToSend = try NSKeyedArchiver.archivedData(withRootObject: dictionary, requiringSecureCoding: false)
try session.send(dataToSend, toPeers: targetPeers, with: MCSessionSendDataMode.reliable)
}
catch {
#if DEBUG
print("CONNECTION MANAGER SEND DATA ERROR")
#endif
}
}
I have been doing research and found that I need to fragment data and send and receive it in packages. But I could not find a good explanation how to do it.
Any help would be appreciated!
