Facebook iOS SDK 在应用启动时挂起

Question

我还没有在 appDidFinishLoadingWithOptions: 中启动任何 facebook 视图或方法：但是当我首先启动应用程序，然后停止并重新启动它时，它会挂起。如果我按下暂停按钮，我可以看到图像中显示的堆栈跟踪。

applicationDidBecomeActive 方法中的这段代码造成了问题。任何人都知道可能是什么原因。删除它解决了我的问题。

- (void)applicationDidBecomeActive:(UIApplication *)application {

if (FBSession.activeSession.state == FBSessionStateCreatedOpening) {
[FBSession.activeSession close]; // so we close our session and start over
}

if (FBSession.activeSession.isOpen) {
}

}

实际上你必须将页面导航到另一个视图控制器，所以试试这个。

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];

UIViewController *splashController = [[UIViewController alloc]init];
UINavigationController *detailednewscontroller=[[UINavigationController alloc]initWithRootViewController:splashController];
[self.window setRootViewController:detailednewscontroller];
[self.window makeKeyAndVisible];
return YES;
}
