iOS : How to enable Audio directions on Google Maps
提问by Azhar
I am using the below code to open Google Maps from my iOS application where I am passing starting and End point of places.
我正在使用下面的代码从我的 iOS 应用程序打开 Google 地图，我正在传递地点的起点和终点。
It navigates correctly from start point to end point but does not guide through Audio (voice).
它从起点到终点正确导航，但不引导音频（语音）。
I want to enable voice guidance facility.
我想启用语音指导功能。
please help
请帮忙
ClientState *clientState = [ClientState sharedInstance];
CLLocation *currentLocation = clientState.currentLocation;
NSString *googleMapsURLString = [NSString stringWithFormat:@"maps://maps.google.com/?xyz=xyz&saddr=%1.8f,%1.8f&daddr=%@,%@",
currentLocation.coordinate.latitude, currentLocation.coordinate.longitude, trip.pickupLatitude, trip.pickupLongitude];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:googleMapsURLString]];

The Maps app will handle audio guidance for you. You do not need to enable it. If you open the Apple Maps URL scheme or Google Maps app, it will guide the user via audio if they have their audio turned on. Voice directions only work on certain phones for the Apple Maps App. The iPhone 5 and 4S have voice direction, while the iPhone 4 and 3GS do not. Just like there is no Siri on iPhone 4, there is no Siri Voice Navigation.
地图应用程序将为您处理音频指南。您不需要启用它。如果您打开 Apple Maps URL scheme 或 Google Maps 应用程序，如果用户打开了音频，它将通过音频引导用户。语音导航仅适用于 Apple Maps App 的某些手机。iPhone 5 和 4S 有语音指示，而 iPhone 4 和 3GS 没有。就像 iPhone 4 上没有 Siri 一样，也没有 Siri 语音导航。
