我是这样解决的问题：
RCTWeChat.h 添加

(instancetype) shareInstance;
(BOOL)handleOpenURL:(NSURL *)url;

RCTWeChat.m
去掉

(instancetype)init
(BOOL)handleOpenURL:(NSNotification *)aNotification
(void)dealloc
(dispatch_queue_t)methodQueue
然后添加
static RCTWeChat * instance = nil; //放在@implementation RCTWeChat前
(instancetype)shareInstance {
@synchronized(self) {
if (!instance) {
instance = [[self alloc] init];
}
}
return instance;
}
(instancetype)allocWithZone:(NSZone *)zone {
@synchronized(self) {
if (!instance) {
instance = [super allocWithZone:zone];
}
}
return instance;
}
(instancetype)copyWithZone:(NSZone *)zone {
return self;
}
(BOOL)handleOpenURL:(NSURL *)url
{
NSLog(@"+++++++++++++++ handleOpenURL %@", url);
return [WXApi handleOpenURL:url delegate:self];
}

AppDelegate.m 添加

(BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options
{
return [[RCTWeChat shareInstance] handleOpenURL: url];
}

@damly 可以给出一段重现bug的代码么？

yorkie on 29 Sep 2016

    try {
        WeChat.registerApp(this.appId);
        let result = await WeChat.pay(
            {
                partnerId: options.partnerId, // 商家向财付通申请的商家id
                prepayId: options.prepayId, // 预支付订单
                nonceStr: options.nonceStr, // 随机串，防重发
                timeStamp: options.timeStamp, // 时间戳，防重发
                package: options.package, // 商家根据财付通文档填写的数据和签名
                sign: options.sign // 商家根据微信开放平台文档对数据做的签名
            }
        );
        console.log('>>>>>>>>>>> pay',result); //未执行
        alert("Pay success!"); //未执行
        success();
    } catch (error) {
        console.log('Pay for failure!'); //未执行
        alert("Pay for failure!"); //未执行
        faile(error);
    }

@damly 可以帮忙debug一下这里么：https://github.com/weflex/react-native-wechat/blob/master/index.js#L203 看看这个函数有没有调用

yorkie on 29 Sep 2016

@yorkie 目标机iOS 10系统

return new Promise((resolve, reject) => {
WeChat.pay(data, (result) => {
if (result) reject(result);
});
emitter.on('PayReq.Resp', (resp) => {
console.log('>>>>>>>>>>> PayReq.Resp'); //未执行
alert(pay);
const result = resp.errCode;
if (result === 0) {
resolve(resp.returnKey);
} else {
reject(result);
}
});

哪里有简单的 react-native-wechat的支付 example 可以做对比测试的？

可以分享和登录么？

yorkie on 29 Sep 2016

登录和分享暂时没有用没有写相关的代码

damly on 29 Sep 2016

那应该是签名问题，请核对下你的ID后，在重新build一下！

yorkie on 29 Sep 2016

@yorkie
能正常分享，并且能正常返回

damly on 29 Sep 2016

那支付么？

yorkie on 29 Sep 2016

@yorkie 能支付成功但是就是不回调onResp

damly on 29 Sep 2016

但是就是不回调onResp

是说 await 之后，不会执行是么？

yorkie on 29 Sep 2016

@yorkie 是的
