iOS调RN方法，bridge爆错

Q:

今天调试极光推送，需要iOS主动调用RN的方法，sendAppEvent，参考博客：http://blog.csdn.net/horisea/article/details/54176417

但是，sendAppEvent这个方法，在0.43之后就不建议使用了，可以用sendEvent，至于出现bridge找不到的情况，大家可以自行参考该文：https://github.com/facebook/react-native/issues/8714

A:

so,我目前的解决方法如下，如果有更好的办法， 欢迎大佬告知（手动比心❤️）:

//  RNBridgeTools.h

#import <Foundation/Foundation.h>

#import <React/RCTBridgeModule.h>
#import <React/RCTEventEmitter.h>


@interface RNBridgeTools : RCTEventEmitter <RCTBridgeModule>
+ (RNBridgeTools *)sharedInstance;

//把推送消息体，推给RN
- (void)callRNWithNotificationInfo:(NSDictionary *)info;

//TouchId的结果回调
- (void)touchIdVerity:(BOOL)success error:(NSError *)error;

@end

//  RNBridgeTools.m

#import "RNBridgeTools.h"
#import <React/RCTEventDispatcher.h>
#import <React/RCTLog.h>

@implementation RNBridgeTools
RCT_EXPORT_MODULE();

+ (RNBridgeTools *)sharedInstance
{
  __strong static RNBridgeTools * tools = nil;
  if (tools) {
    return tools;
  }
  
  static dispatch_once_t d;  
  dispatch_once(&d, ^{
    tools = [[RNBridgeTools alloc] init];
  });
  
  return tools;
}

- (NSArray<NSString *> *)supportedEvents
{
  return @[@"iOSRemoteNotification",@"iOSTouchIdVerity"];
}

#pragma mark - 把推送信息，推给RN
- (void)callRNWithNotificationInfo:(NSDictionary *)info
{
  [self.bridge.eventDispatcher sendAppEventWithName:@"iOSRemoteNotification" body:info];
}

#pragma mark - TouchId的结果回调
- (void)touchIdVerity:(BOOL)success error:(NSError *)error
{
  NSMutableDictionary *dict = [NSMutableDictionary dictionary];
  [dict setObject:[NSNumber numberWithBool:success] forKey:@"success"];
  [dict setObject:[NSNumber numberWithInteger:error.code] forKey:@"errorCode"];
  [dict setObject:error.localizedDescription forKey:@"errorInfo"];
  
  [self.bridge.eventDispatcher sendAppEventWithName:@"iOSTouchIdVerity" body:dict];
}

@end

PS: 极光推送提供了 ReactNative 支持包，想用的同学可以参考：https://github.com/jpush/jpush-react-native
