Question

我正在从旧导航器迁移到react-native-navigation。我已按照here的指南进行操作，但现在我的应用只会加载启动画面并且从不加载第一个屏幕。

我收到警告信息：

需要dispatch_syng来加载RNDeviceInfo的常量。这可能会导致死锁

我认为之前没有这样的警告信息，但我不确定。

这是我的AppDelegate.m：

#import "AppDelegate.h"
#import <CodePush/CodePush.h>
#import <FBSDKCoreKit/FBSDKCoreKit.h>

#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
#import <React/RCTLinkingManager.h>
#import <RNGoogleSignin/RNGoogleSignin.h>
#import <Firebase.h>
#import "RCCManager.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
  return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                        openURL:url
                                              sourceApplication:sourceApplication
                                                     annotation:annotation
          ]
  || [RNGoogleSignin application:application
                         openURL:url
               sourceApplication:sourceApplication
                      annotation:annotation
      ];
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
  [FBSDKAppEvents activateApp];
}

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity
 restorationHandler:(void (^)(NSArray * _Nullable))restorationHandler
{
  return [RCTLinkingManager application:application
                   continueUserActivity:userActivity
                     restorationHandler:restorationHandler];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  NSURL *jsCodeLocation;

  [[FBSDKApplicationDelegate sharedInstance] application:application
                           didFinishLaunchingWithOptions:launchOptions];

#ifdef DEBUG
    jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
#else
    jsCodeLocation = [CodePush bundleURL];
#endif

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  self.window.backgroundColor = [UIColor whiteColor];
  [[RCCManager sharedInstance] initBridgeWithBundleURL:jsCodeLocation launchOptions:launchOptions];

  [FIRApp configure];
  return YES;
}

@end

我正在使用：

react 16.0.0
react-native 0.47.2
react-native-navigation 1.1.262

我正在使用npm版本5.3.0安装react-native导航

使用react-native-navigation后，屏幕无法启动
