IOS没回调且不返回App about react-native-alipay

[fanriver]

好像是这里的代码被注释了
iOS/RCTAlipay.m

RCT_EXPORT_METHOD(payInterceptorWithUrl:(NSString *)urlStr
                  resolver:(RCTPromiseResolveBlock)resolve
                  rejecter:(RCTPromiseRejectBlock)reject) {
    [AlipaySDK.defaultService payInterceptorWithUrl:urlStr fromScheme:self.appScheme callback:^(NSDictionary *resultDic) {
        resolve(resultDic);    // 这里的注释去除
    }];
}

另外URL types alipay对应的那一项要写URL Scheme，随便写个纯字母的字符串就可以了

@0x5e 这个是什么原因，可以修复一下吗

没回调的问题已经解决
解决方法：
AlipayModule.m
#import "AlipayModule.h"

#import <AlipaySDK/AlipaySDK.h>

@implementation AlipayMoudle

RCT_EXPORT_METHOD(pay:(NSString *)orderInfo
resolver:(RCTPromiseResolveBlock)resolve
rejecter:(RCTPromiseRejectBlock)reject){

NSString *appScheme = @"alipay2019082766518009";
 dispatch_async(dispatch_get_main_queue(), ^{
 
    [[AlipaySDK defaultService] payOrder:orderInfo fromScheme:appScheme        callback:^(NSDictionary *resultDic) {
         
       resolve(resultDic);
         
     }];
   
 });

}

RCT_EXPORT_MODULE(Alipay);
@EnD

在AppDelegate.m

• (BOOL)application:(UIApplication *)application
  openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
  annotation:(id)annotation {

  if ([url.host isEqualToString:@"safepay"]) {
  //跳转支付宝钱包进行支付，处理支付结果
  [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:nil];
  return YES;
  }else{
  return [RCTLinkingManager application:application openURL:url
  sourceApplication:sourceApplication annotation:annotation];
  }

}

// NOTE: 9.0以后使用新API接口

• (BOOL)application:(UIApplication *)app openURL:(NSURL )url options:(NSDictionary<NSString, id> *)options
  {
  if ([url.host isEqualToString:@"safepay"]) {
  //跳转支付宝钱包进行支付，处理支付结果

  [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:nil];

  return YES;
  }else{
  return [RCTLinkingManager application:app openURL:url options:options];

  }

}

推荐使用@uiw/react-native-alipay吧，文档清晰，配置少，很好用的插件。

大佬，我的RN是0.57.6版本，可以用这个插件吗？
