iOS 微信支付不走回调onResp

当其他配置没问题的时候，一定要检查UniversalLinks

[WXApi registerApp:WXAPPID universalLink:WXUniversalLinks];

UniversalLinks检查，仅测试环境使用，要求微信sdk>1.8.7

//在register之前打开log, 后续可以根据log排查问题
[WXApi startLogByLevel:WXLogLevelDetail logBlock:^(NSString *log) {
    NSLog(@"WeChatSDK: %@", log);
}];

//务必在调用自检函数前注册
[WXApi registerApp:APP_ID universalLink:UNIVERSAL_LINK];

//调用自检函数
[WXApi checkUniversalLinkReady:^(WXULCheckStep step, WXCheckULStepResult* result) {
    NSLog(@"%@, %u, %@, %@", @(step), result.success, result.errorInfo, result.suggestion);
}];

    if([resp isKindOfClass:[PayResp class]]){
        switch (resp.errCode) {
            case WXSuccess:
                NSLog(@"支付成功－PaySuccess，retcode = %d", resp.errCode);
                break;
                
            default:
                NSLog(@"错误，retcode = %d, retstr = %@", resp.errCode,resp.errStr);
                break;
        }
    }else {
        
    }
}

- (void)onReq:(BaseReq *)req {
    
}
@end

设置代理方法

AppDelegate

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options{
    
    // 微信的支付回调
    if ([url.scheme isEqualToString:WXAPPID]){
        return [WXApi handleOpenURL:url delegate:[WXApiManager sharedManager]];
    }
        return YES;
}

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void(^)(NSArray<id<UIUserActivityRestoring>> * __nullable restorableObjects))restorationHandler {
    return [WXApi handleOpenUniversalLink:userActivity delegate:[WXApiManager sharedManager]];
}
