我正在尝试使用 Gamekit 连接两个设备并传输少量数据。我可以使用 GKPickerController 做到这一点，但现在为了让用户体验更好一点，我正在尝试自动实现这一点。问题是delgate方法
- (void)session:(GKSession *)session peer:(NSString *)peerID didChangeState:(GKPeerConnectionState)state
没有被调用。
这也是两个不同的应用程序。
请在下面找到代码：
iPad app
AppDelegate.h
@interface AppDelegate : UIResponder <UIApplicationDelegate,GKSessionDelegate>
@property (strong, nonatomic) UIWindow *window;
@property (nonatomic, retain) GKSession *connectSession;
@end
AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
_peerDevice = [[NSMutableArray alloc]init];
_connectSession = [[GKSession alloc]initWithSessionID:nil displayName:nil sessionMode:GKSessionModePeer];
_connectSession.delegate = self;
_connectSession.available = YES;
_connectSession.disconnectTimeout = 0;
[_connectSession setDataReceiveHandler:self withContext:nil];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[xyz alloc] initWithNibName:@"xyz" bundle:nil];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
- (void)session:(GKSession *)session peer:(NSString *)peerID didChangeState:(GKPeerConnectionState)state{
if(state == GKPeerStateConnected){
// Add the peer to the Array
[_peerDevice addObject:peerID];
NSString *str = [NSString stringWithFormat:@"Connected with %@",[session displayNameForPeer:peerID]];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Connected" message:str delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
// Used to acknowledge that we will be sending data
[session setDataReceiveHandler:self withContext:nil];
[[self.window viewWithTag:12] removeFromSuperview];
}
}
- (void)session:(GKSession *)session didReceiveConnectionRequestFromPeer:(NSString *)peerID
{
NSLog(@"didReceiveConnectionRequestFromPeer: %@", [session displayNameForPeer:peerID]);
[session acceptConnectionFromPeer:peerID error:nil];
}
