[英]connecting 2 devices over different WiFi network using GKSession
I am trying to connect 2 devices using GKSession. 我正在尝试使用GKSession连接2个设备。 When the devices are on same WiFi network it is working but when i am trying to connect devices on different WiFi network it is not working. 当设备在同一个WiFi网络上时,它正在工作,但当我尝试连接不同WiFi网络上的设备时,它无法正常工作。 This is my code for GKSession 这是我的GKSession代码
chatSession = [[GKSession alloc] initWithSessionID:AppName displayName:name sessionMode:GKSessionModePeer];
[chatSession setDataReceiveHandler:self withContext:nil];
chatSession.delegate = self;
chatSession.available = YES;
-(void)session:(GKSession *)session peer:(NSString *)peerID didChangeState:(GKPeerConnectionState)state{
NSLog(@"state=%d", state);
if(state == GKPeerStateDisconnected)
{
// A peer disconnected
chatSession.available = YES;
NSLog(@"Disconnected");
[data removeAllObjects];
chatInput.hidden = YES;
}
else if(state == GKPeerStateConnected)
{
// You can now send messages to the connected peer(s)
NSData *imgData = UIImageJPEGRepresentation(myImage, 0.5);
if(imgData==nil)
NSLog(@"myImage is nil");
NSError *err;
//NSLog(@"pid=%@", pID);
NSLog(@"before sending image");
[chatSession sendData:imgData toPeers:[NSArray arrayWithObject:pID] withDataMode:GKSendDataReliable error:&err];
NSLog(@"after send data");
if(err)
NSLog(@"error:%@", err.description);
}
else if (state == GKPeerStateAvailable)
{
pID = peerID;
[session connectToPeer:peerID withTimeout:60*120];
}
} }
-(void)session:(GKSession *)session didReceiveConnectionRequestFromPeer:(NSString *)peerID{
// We can now decide to deny or accept
bool shouldAccept = YES;
if(shouldAccept)
{
pID = peerID;
[session acceptConnectionFromPeer:peerID error:nil];
}
else
{
[session denyConnectionFromPeer:peerID];
}}
I am not sure if it is possible using GKSession. 我不确定是否可以使用GKSession。
According to Apple 根据Apple的说法
A GKSession object provides the ability to discover and connect to nearby iOS devices using Bluetooth or Wi-fi. GKSession对象提供使用蓝牙或Wi-Fi发现和连接到附近iOS设备的功能。
Please help me ia m trying to create a chat app using GKSession. 请帮助我尝试使用GKSession创建聊天应用程序。
iOS' GameKit most probably uses Bonjour for this, which works by doing broadcasts on a local network. iOS'GameKit最有可能使用Bonjour ,这可以通过在本地网络上进行广播来实现。 It won't work between two separate Wi-Fi networks. 它不适用于两个独立的Wi-Fi网络。
This means you'll need a central server (at least during connection set-up). 这意味着您将需要一个中央服务器(至少在连接设置期间)。 Have a look at XMPP , if you haven't done so already. 如果您还没有这样做,请查看XMPP 。
Good luck! 祝好运!
