在HERE sdk ios中设置语音

Question

我在这里使用地图。我试图设置声音在轮流导航，但我不能做到这一点。我尝试用NMAVoicePackage设置声音，但我不知道如何设置。下面的代码是我尝试的。

NMAVoiceCatalog *voiceCatalog = [NMAVoiceCatalog sharedVoiceCatalog];
NMAVoicePackage *voicepackeg=[voiceCatalog.voicePackages objectAtIndex:0];
[voiceCatalog installVoicePackage:voicepackeg]
 [[NMANavigationManager sharedNavigationManager] setVoicePackage:voicepackeg];
   NSError *error;
    NSLog(@"starting navigation simulation");
    error = [[NMANavigationManager sharedNavigationManager] startTurnByTurnNavigationWithRoute:self.route];
    if(error && error.code != NMANavigationErrorNone){
        NSLog(@"ERROR: failed to start simulation with error code %ld", (long)error.code);
        return;
    }

请检查您的导航模式设置为驾驶

语音指令只能在导航模式下使用。行人导航模式的用户在每次移动时都会收到音频蜂鸣声和振动警报。链接
