嗨其他软件enthousiasts,

我目前正在研究一个React本机项目,我需要添加一些用swift编写的逻辑.我能够通过桥接到Objective C然后到Swift来触发一个基本的swift函数.

当我尝试用promises做某事时会出现问题.我描述的这个页面在Promise的Objective C部分和Swift的桥接上是清楚的,但对swift的承诺却不是这样:https://facebook.github.io/react-native/docs/native-modules-ios html的

这就是我所拥有的:

项目桥接,Header.h

#import <React/RCTBridgeModule.h>

MyLoginBridge.m

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

@interface RCT_EXTERN_REMAP_MODULE(MyCustomLoginJSName, MyLoginModule, NSObject)

RCT_EXTERN_REMAP_METHOD(loginWithEmail,
                    resolver:(RCTPromiseResolveBlock)resolve
                    rejecter:(RCTPromiseRejectBlock)reject)

RCT_EXTERN_METHOD(testMethod)

@end

MyLoginModule.swift

import Foundation

@objc(TripleASDKModule)
class TripleASDKModule: NSObject {

  @objc
  func loginWithEmail(resolver resolve: RCTPromiseResolveBlock,  rejecter reject: RCTPromiseRejectBlock) -> Void {
    resolve("This method is troublesome")
  }

  @objc func testMethod() -> Void {
    print("This Does appear")
  }
}

当我触发testMethod时,打印显示在Xcode中,以便执行快速代码.但是当我调用loginWithEmail方法时,我得到臭名昭着的红色React Native错误屏幕说:

Exception 'resolver:(RCTPromiseResolveBlock)resolve rejecter:(RCTPromiseRejectBlock)reject is not a recognized Objective-C method.' was thrown while invoking loginWithEmail on target …
