...

AppDelegate.m

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

...
  // Set Data Center
  [MoEngage setDataCenter:DATA_CENTER_01]; //DATA_CENTER_01, DATA_CENTER_02, OR DATA_CENTER_03
  
  [[MOReactInitializer sharedInstance] intializeSDKWithLaunchOptions:launchOptions];
  
  return YES;
}

【解决方案1】：

MoEngageSDK 仅在 RichLanding 的情况下呈现 ViewController。上面提到的错误指向了

react-native-splash-screen

插件，因为您在 AppDelegate 中调用 [RNSplashScreen show];。所以问题似乎来自react-native-splash-screen插件。

另外，对于另一个错误。你需要确定

[[MOReactInitializer sharedInstance] intializeSDKWithLaunchOptions:launchOptions]

正在正确初始化。

另外，您可以与 moengage 的支持团队联系以解决此问题 https://help.moengage.com/

我已经解决了这个问题，对我来说这是因为文件AppDelegate 中的两行放在了错误的位置。确保这些：

  [MoEngage setDataCenter:DATA_CENTER_01]; //DATA_CENTER_01, DATA_CENTER_02, OR DATA_CENTER_03
  
  [[MOReactInitializer sharedInstance] intializeSDKWithLaunchOptions:launchOptions];

在(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions函数的正确位置，在我的情况下是把它们放在前面：

RCTBridge *bridge = [[RCTBridge alloc] initWithDelegate:self launchOptions:launchOptions];
RCTRootView *rootView = [[RCTRootView alloc] initWithBridge:bridge
                                                   moduleName:@"finan"
                                            initialProperties:nil];

rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];
