反应原生导航中的RCC Manager问题

Question

我试图在反应本机项目中实现react-native-navigation选项卡栏,虽然我一直收到错误:

'undefined不是一个对象(Evaluating RCCManager.setRootController)'.

我首先安装了react-native-navigation,然后是react-native-controllers,然后做了react-native链接(就像教程所说).

这是我的AppDelegate.m代码:

#import "AppDelegate.h"
#import "RCCManager.h"
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)applicationdidFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  NSURL *jsCodeLocation;

  jsCodeLocation = [[RCTBundleURLProvider sharedSettings]jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  self.window.backgroundColor = [UIColor whiteColor];
  [[RCCManager sharedInstance] initBridgeWithBundleURL:jsCodeLocation];

  return YES;
}
