可能是什么问题?
到目前为止它运作良好突然发生了
谢谢所有帮助者
What could be the problem? Until now it worked well suddenly it happened Thank you to all helpers
更新:
@Sviatoslav Yakymiv
found我认为
update: @Sviatoslav Yakymiv found this i think
- (void)authenticateLocalUser {
if (!gameCenterAvailable) return;
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
if (SYSTEM_VERSION_LESS_THAN(@"6.0"))
{
// ios 5.x and below
[localPlayer authenticateWithCompletionHandler:^(NSError *error)
{
[self checkLocalPlayer];
}];
}
else
{
// ios 6.0 and above
[localPlayer setAuthenticateHandler:(^(UIViewController* viewcontroller, NSError *error) {
if (!error && viewcontroller)
{
[viewcontroller presentViewController:viewcontroller animated:YES completion:nil];
}
else
{
[self checkLocalPlayer];
}
})];
}
}
我可以在没有崩溃的情况下改变它吗?
谢谢
What I can change it without a crash? thanks
推荐答案
您正在尝试从其自身呈现控制器。
可能你的代码包含以下内容:
You are attempting to present controller from itself. Probably your code contains something like following:
[self presentViewController:self completion:nil];
现在看到你的代码后,我可以提供工作代码:
Now after I saw your code I can provide working code:
替换
[viewcontroller presentViewController:viewcontroller animated:YES completion:nil];
with
[[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:viewcontroller animated:YES completion:nil];
