我有以下情況。
2 個相同的 react-native 應用程式（僅對 bundleId、應用程式圖示等不同）結構如下：
->專案結構
我的目標是當用戶收到或點擊推送通知時（假設應用程式處于前臺并且應用程式已完成啟動），通過橋從本機端向 JS 層發出事件。在第一個應用程式上，當我使用命令向我的模擬器觸發推送通知時，以下代碼按預期作業xcrun simctl push <device-id> <bundleId> <filename>.apns，第二個應用程式立即崩潰并出現以下錯誤：
Thread 1: "Error when sending event: pushDelivered with body: <the string passed as body>. RCTCallableJSModules is not set. This is probably because you've explicitly synthesized the RCTCallableJSModules in CustomEventsEmitter, even though it's inherited from RCTEventEmitter."
-> xcode 視圖
這是引發斷言的 RCTEventEmitter 的 sendEventWithName 的代碼實作。
我不知道這是否與我的實施有關。在 2 個應用程式中，有一個像魅力一樣作業，另一個 ??。任何人都可以幫我找到代碼中的問題嗎？應該是橋的問題？
我已經嘗試過多次重新安裝 pod、清理專案和重建。該代碼適用于專案A，而不適用于專案B ..我無法弄清楚原因

請幫助我理解
uj5u.com熱心網友回復：
哦，我已經解決了！這是我的一個錯誤。
AppModule 沒有正確呼叫 CustomEventsEmitter 的方法。像下面這樣更改代碼會使事件通過 RN 橋正確發出
-(void)emitPushDeliveredEvent:(NSString*)value {
NSLog(@"emitPushDeliveredEvent called");
[customEventsEmitter sendEventName:@"pushDelivered" body:value];
//[customEventsEmitter sendEventWithName:@"pushDelivered" body:value];
}
-(void)emitPushTappedEvent:(NSString*)value {
NSLog(@"emitPushTappedEvent called");
[customEventsEmitter sendEventName:@"pushTapped" body:value];
//[customEventsEmitter sendEventWithName:@"pushTapped" body:value];
}
