iOS 百度導航沒有語音播報

1.百度地圖沒有語音播報

可以嘗試如下方式：

1.tts確認相關key正確，可以放入官方demo測試

2.setting中 Product Name 嘗試設置成英文，在info.plist設置Bundle display name為app名稱。

3.可以嘗試使用自定義tts方式

[BNaviService_Instance initNaviService:nil success:^{
                 //導航SDK鑒權
                 [BNaviService_Instance authorizeNaviAppKey:BaiduMapKey
                                                 completion:^(BOOL suc) {
                     NSLog(@"authorizeNaviAppKey ret = %d",suc);
                 }];
                 //TTS SDK鑒權
                 [BNaviService_Instance authorizeTTSAppId:BaiduTTS
                                                   apiKey:TTS_API_KEY
                                                secretKey:TTS_SECRET_KEY
                                               completion:^(BOOL suc) {
                     NSLog(@"authorizeTTS ret = %d",suc);
                 }];
                 // 設置BNNaviSoundDelegate 代理
                 [BNaviService_Sound setSoundDelegate:self];
             } fail:^{
                 NSLog(@"initNaviSDK fail");
             }];
#pragma mark - BNNaviSoundDelegate

    NSLog(@"onPlayTTS text = %@", text);
    BOOL istts = [BNaviService_Sound isTTSPlaying];
    BOOL s = [BNaviService_Sound resume];
    BOOL p = [BNaviService_Sound playText:text];
    //        自定義語音播報
    [self customSound:text];
    NSLog(@"istts:%d,s:%d,p:%d",istts,s,p);
