iOS 百度导航没有语音播报

1.百度地图没有语音播报

可以尝试如下方式：

1.tts确认相关key正确，可以放入官方demo测试

2.setting中 Product Name 尝试设置成英文，在info.plist设置Bundle display name为app名称。

3.可以尝试使用自定义tts方式

[BNaviService_Instance initNaviService:nil success:^{
                 //导航SDK鉴权
                 [BNaviService_Instance authorizeNaviAppKey:BaiduMapKey
                                                 completion:^(BOOL suc) {
                     NSLog(@"authorizeNaviAppKey ret = %d",suc);
                 }];
                 //TTS SDK鉴权
                 [BNaviService_Instance authorizeTTSAppId:BaiduTTS
                                                   apiKey:TTS_API_KEY

                                               completion:^(BOOL suc) {
                     NSLog(@"authorizeTTS ret = %d",suc);
                 }];
                 // 设置BNNaviSoundDelegate 代理
                 [BNaviService_Sound setSoundDelegate:self];
             } fail:^{
                 NSLog(@"initNaviSDK fail");
             }];
