xCode 在运行应用程序时与设备失去连接

Question

我一直在构建一个 iOS 应用程序，并且一直在模拟器和我的 iPad 上测试它。一切正常，直到-
当我最近添加代码以注册推送通知到我的 AppDelegate.m 文件时。现在，当我尝试运行设备上的应用程序时，该应用程序会在初始屏幕上停留一段时间，然后 xCode 出现以下错误。

process launch failed: timed out waiting for app to launch

这是我添加的代码，以防万一：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
 // Override point for customization after application launch.

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
   if ([[UIApplication sharedApplication]respondsToSelector:@selector(registerUserNotificationSettings:)])
   {
      UIUserNotificationType userNTypes = (UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound);

      UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNTypes categories:nil];

        NSLog(@"sherikkum registering 8.xx...");

      [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
      [[UIApplication sharedApplication] registerForRemoteNotifications];
   }
   else
   {
      [[UIApplication sharedApplication] registerForRemoteNotificationTypes: 
      (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}
#else
   [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
   (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

#endif

return YES;
}

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
  NSLog(@"My token is: %@", deviceToken);

  //I added this alert coz i couldnt view NSLogs - coz my xcode wont connect
  UIAlertView *tokenalert = [[UIAlertView alloc] initWithTitle:@"Token"
                                                     message:[NSString stringWithFormat:@"%@",deviceToken]
                                                    delegate:nil
                                           cancelButtonTitle:@"OK"
                                           otherButtonTitles:nil, nil];
  [tokenalert show];
}

- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
   NSLog(@"Failed to get token, error: %@", error);
}

谢谢

您在运行安装您的应用时可能使用的是分发证书而不是开发人员证书。在 Target => Build Settings=> Code Signing.

中更改它

如果您正在使用从分发证书创建的配置文件，您的代码将不会运行在运行来自 xcode 的设备上。您需要使用从开发证书创建的配置文件。有关配置文件和证书的更多详细信息，请阅读 Apple's Documentation.
