我正在沙盒模式下在我的应用程序中实现游戏中心。当我登录到gameCenter时会出现问题,在某些设备上工作正常,我得到的是GKErrorCanceled,甚至没有显示界面。
此设备没有任何用户登录gameCenter,因此与记录非沙盒帐户无关。我的代码是:
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
//First we try the new iOS6 authentification method for gamekit, if it's not implemented we will use the deprecated one
if ([localPlayer respondsToSelector:@selector(setAuthenticateHandler:)]) {
if (localPlayer.isAuthenticated) {
this->setState(connectionLoged);
this->getDelegate().socialConnectionDidSucceedLogin(*this);
return;
}
else if(!localPlayer.isAuthenticated && localPlayer.authenticateHandler){
this->setState(connectionClosed);
this->getDelegate().socialConnectionDidFailToLogin(*this, std::string("The user already resign to login"));
return;
}
else{
localPlayer.authenticateHandler = ^(UIViewController* viewController, NSError* error){
if (localPlayer.isAuthenticated)
{
_name = [localPlayer.displayName UTF8String];
_userId = [localPlayer.playerID UTF8String];
[GKPlayer loadPlayersForIdentifiers:localPlayer.friends withCompletionHandler:^(NSArray *players, NSError *error) {
for (GKPlayer* player in players) {
if ([player isFriend]) {
NSDictionary* dict =
@{@"displayName" : player.displayName,
@"alias" : player.alias,
@"playerID" : player.playerID};
AttrDictionary* playerInfo = [dict hydraAttrDictionary];
SocialFriend* socialfriend = this->getNewFriendInstance(*playerInfo);
this->addFriend(socialfriend);
delete playerInfo;
}
}
this->getDelegate().socialConnectionDidSucceedLogin(*this);
this->setState(connectionLoged);
}];
}
else if(viewController){
UIViewController* rootViewController = (UIViewController*) [UIApplication sharedApplication].keyWindow.rootViewController ;
[rootViewController presentModalViewController:viewController animated:YES];
}
else{
if(error){
this->getDelegate().socialConnectionDidFailToLogin(*this, std::string([error.description UTF8String]));
}
else{
this->getDelegate().socialConnectionDidFailToLogin(*this, std::string("User cancelled login"));
}
}
};
}
}
//deprecated at IOs 6 authentification method
else
[localPlayer authenticateWithCompletionHandler:^(NSError *error) {
if (localPlayer.isAuthenticated)
{
_name = [localPlayer.displayName UTF8String];
_userId = [localPlayer.playerID UTF8String];
[GKPlayer loadPlayersForIdentifiers:localPlayer.friends withCompletionHandler:^(NSArray *players, NSError *error) {
for (GKPlayer* player in players) {
if ([player isFriend]) {
NSDictionary* dict =
@{@"displayName" : player.displayName,
@"alias" : player.alias,
@"playerID" : player.playerID};
AttrDictionary* playerInfo = [dict hydraAttrDictionary];
SocialFriend* socialfriend = this->getNewFriendInstance(*playerInfo);
this->addFriend(socialfriend);
delete playerInfo;
}
}
this->getDelegate().socialConnectionDidSucceedLogin(*this);
this->setState(connectionLoged);
}];
}
else{
NSString* errorString = [error localizedDescription];
this->getDelegate().socialConnectionDidFailToLogin(*this, std::string([errorString UTF8String]));
this->setState(connectionClosed);
}
}];
我需要与iOS 6和iOS 5兼容的代码,因此您将看到我有两个实现。对于iOS 6,完成处理程序返回UIViewController null和我说的错误。我担心在生产中它会发生同样的事情。在模拟器中一切正常。
PS-你会发现一些c ++代码,因为我为GameCenter实现了一个c ++包装器,因为我的游戏是用cocos2dx编写的......
答案 0 :(得分:3)
当某人取消退出界面登录游戏中心时,它会给你GKErrorCanceled。他们连续第三次取消,它会警告他们将禁用游戏中心。
如果他们确实选择禁用游戏中心,那么它将不再显示界面,它只会给你GKErrorCanceled。
一旦游戏中心被禁用,登录的唯一方法是进入实际的游戏中心应用程序。
连续3次可以在使用游戏中心的任何应用程序或任何应用程序组合中,并且将禁用所有使用游戏中心的应用程序的游戏中心。每次登录游戏中心时,连续3次重启。
这适用于沙箱和非沙箱。
这适用于ios 5和ios 6.
