我正在使用本机模块构建本机反应。在 javascript 方面，我想在 iOS 上为侦听器事件创建本机模块，并从 javascript 端调用一些方法。我在 Objective C 中有一个静态 NSDictionary 变量。但是当我得到变量的值时，它显示 EXC_BAD_ACCESS。我正在使用本机模块构建本机反应。在 javascript 方面，我想在 iOS 上为侦听器事件创建本机模块，并从 javascript 端调用一些方法。这是我的代码

DeepLinkController.js

import React, {Component} from 'react';
import {Platform, Linking, View, NativeModules, NativeEventEmitter} from 'react-native'
const DeeplinkManager = new NativeEventEmitter(NativeModules.DeeplinkManager);
const TestMethod = NativeModules.TestMethod;

class DeepLinkController extends Component{
  componentDidMount(){
    TestMethod.notifyAppMount();
    DeeplinkManager.addListener('DeepLink', this.handleDeepLink);
  }

  componentWillUnmount(){
    TestMethod.notifyAppUnMount();
    DeeplinkManager.removeListener('DeepLink', this.handleDeepLink);
  }

  handleDeepLink = (event) => {
    //navigate url
  }

  render(){
  }
}

在 Objective-C 中，我创建：DeeplinkManager.h、DeeplinkManager.m、TestMethod.h、TestMethod.m

DeeplinkManager.h
#if __has_include("RCTEventEmitter.h")
#import "RCTEventEmitter.h"
#else
#import <React/RCTEventEmitter.h>
#endif


NS_ASSUME_NONNULL_BEGIN

static bool isAppMount = false, isNavigateNotitication = false;
static NSMutableDictionary<NSMutableString *, id> *resultTemp;


@interface DeeplinkManager : RCTEventEmitter <RCTBridgeModule>

+ (void)notifyAppMount;
+ (void)notifyAppUnMount;
+ (void)emitEventWithDeeplink:(NSString *)deeplink andPayload:(NSDictionary *)payload;
@end

#import "DeeplinkManager.h"

@implementation DeeplinkManager
RCT_EXPORT_MODULE();

- (void)startObserving
{
  [[NSNotificationCenter defaultCenter] addObserver:self
                                           selector:@selector(sendDeeplink:)
                                               name:@"Deeplink"
                                             object:nil];
}

- (void)stopObserving
{
  [[NSNotificationCenter defaultCenter] removeObserver:self];
}


- (void)sendDeeplink:(NSNotification *)notifcation {
  NSDictionary<NSString *, id> *payload = @{@"deeplink": notifcation.userInfo[@"deeplink"],@"userInfo":notifcation.userInfo[@"userInfo"]};
  [self sendEventWithName:@"Deeplink" body:payload];
}

+ (void)emitEventWithDeeplink:(NSString *)deeplink andPayload:(NSDictionary *)payload {
    isNavigateNotitication = true;
    resultTemp = @{@"deeplink": deeplink,@"userInfo":payload};
}

RCT_EXPORT_METHOD(getInitialDeeplink:(RCTPromiseResolveBlock)resolve
                  reject:(__unused RCTPromiseRejectBlock)reject)
{
    //some code for handle get initial deeplink
}


+(void)notifyAppMount {
    NSDictionary<NSString *, id> *userInfo = resultTemp;
    [[NSNotificationCenter defaultCenter] postNotificationName:@"SMTDeeplink"
                                                        object:self
                                                      userInfo:userInfo];
  }
}

+(void)notifyAppUnMount {
  isAppMount = false;
}

@end

---TestMethod.h
#import <React/RCTBridgeModule.h>
@interface TestMethod : NSObject <RCTBridgeModule>
@end

--- TestMethod.m
#import "TestMethod.h"
#import "DeeplinkManager.h"
@implementation TestMethod

RCT_EXPORT_MODULE();

RCT_EXPORT_METHOD(notifyAppMount)
{
 [DeeplinkManager notifyAppMount];
}

RCT_EXPORT_METHOD(notifyAppUnMount)
{
  [DeeplinkManager notifyAppUnMount];
}
@end

当我的应用程序挂载时，它会调用 TestMethod.notifyAppMount。然后我推送通知，它会将参数设置为 resultTemp 变量。当我按下按钮时调用 TestMethod.notifyAppMount() 时，此代码显示：EXC_BAD_ACCESS。

+(void)notifyAppMount {
    NSDictionary<NSString *, id> *userInfo = resultTemp;
    [[NSNotificationCenter defaultCenter] postNotificationName:@"Deeplink"
                                                        object:self
                                                      userInfo:userInfo];
  }
}

在 javascriptside 中，我也不能调用 DeeplinkManager.getInitialDeeplink() 尽管在 deeplink 模块中我声明了方法。先感谢您。
