所以我有一个使用Game Center的游戏,我使用了tutorial online.它在View加载时对用户进行身份验证。要查看排行榜和成就,请按一个按钮,该代码与身份验证分开。一切正常,直到我以飞行模式启动应用程序。出于某种原因,由于它无法连接到Game Center服务器,因此它会放弃并崩溃。
验证码(ViewController.m,viewDidLoad)
if ([GKLocalPlayer localPlayer].authenticated == NO) {
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
[localPlayer setAuthenticateHandler:(^(UIViewController* viewcontroller, NSError *error) {
})];
} else {
NSLog(@"Already authenticated!");
}
另外,我认为这不会导致问题,因为它在启动时崩溃,我不知道这个代码是否在启动时运行。 (我从教程中复制了大部分代码),但这里是:
(GCHelper.m)
#pragma mark Authentication
- (void)authenticationChanged {
if ([GKLocalPlayer localPlayer].isAuthenticated && !userAuthenticated) {
NSLog(@"Authentication changed: player authenticated.");
userAuthenticated = TRUE;
[self loadLeaderBoardInfo];
// [self loadAchievements];
} else if (![GKLocalPlayer localPlayer].isAuthenticated && userAuthenticated) {
NSLog(@"Authentication changed: player not authenticated.");
userAuthenticated = FALSE;
}
}
- (void)authenticateLocalUserOnViewController:(UIViewController*)viewController
setCallbackObject:(id)obj
withPauseSelector:(SEL)selector
{
if (!gameCenterAvailable) return;
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
NSLog(@"Authenticating local user...");
if (localPlayer.authenticated == NO) {
[localPlayer setAuthenticateHandler:^(UIViewController* authViewController, NSError *error) {
if (authViewController != nil) {
if (obj) {
[obj performSelector:selector withObject:nil afterDelay:0];
}
[viewController presentViewController:authViewController animated:YES completion:^ {
}];
} else if (error != nil) {
// process error
}
}];
}
else {
NSLog(@"Already authenticated!");
}
}
我的问题是,为什么在飞机模式下发射时会崩溃?这是错误消息:
2014-10-28 16:18:05.895 Rock Paper Scissors Challenge [10372:704073] - [GKLocalPlayerInternal name]:无法识别的选择器发送到实例0x7ced9750
2014-10-28 16:18:05.992 Rock Paper Scissors Challenge [10372:704073] *由于未捕获的异常'NSInvalidArgumentException'而终止应用程序,原因:' - [GKLocalPlayerInternal name]: 无法识别的选择器发送到实例0x7ced9750' * 首先抛出调用堆栈:
100%的时间在飞机模式下崩溃,100%的时间都在工作,当我不在飞机模式时它会说“欢迎回来”我没有得到它
请帮助,谢谢!
