应用程序无法及时启动 [英] Application Failed to Launch in Time

问题描述

如何诊断此错误？

Application Specific Information:
    MyApp failed to launch in time

    Elapsed total CPU time (seconds): 4913.443 (user 3868.270, system 1045.173), 56% CPU 
    Elapsed application CPU time (seconds): 0.010, 0% CPU

    Backtrace not available

    Unknown thread crashed with unknown flavor: 5, state_count: 1

这是我的 didFinishLaunching 方法：

#pragma mark -
#pragma mark Application lifecycle

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

        if(getenv("NSZombieEnabled") || getenv("NSAutoreleaseFreedObjectCheckEnabled")) 
        {
            NSLog(@"NSZombieEnabled/NSAutoreleaseFreedObjectCheckEnabled enabled!");
        }

        // Override point for customization after application launch.
        [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(reachabilityChanged:) name: kReachabilityChangedNotification object: nil];

        //Check for connectivity
        internetReach = [[Reachability reachabilityForInternetConnection] retain];
        [internetReach startNotifer];
        [self updateInterfaceWithReachability: internetReach];

        [window addSubview:navigationController.view];
        [window makeKeyAndVisible];

        return YES;
    }

推荐答案

你可能在做您的AppDelegate的应用程序中的大量设置工作：didFinishLaunching 方法。

You're probably doing a lot of setup work in your AppDelegate's application:didFinishLaunching method.

您应该确保此功能尽快退出。需要时间的任何设置工作（例如网络访问）都应该在应用程序中异步执行。当这种情况发生时，您可以显示一个微调器向用户显示应用程序正在加载。

You should make sure this function exits as soon as possible. Any setup-work that takes time (network access for example) should be done asynchronously in your application. While this is going on, you can show a spinner to indicate to the user that the application is loading.
