Question

我正在使用谷歌地图sdk，现在我想在谷歌地图中打开获取方向，其中有多个站点，就像我在位置 A ，从我想要的去 B，C，D 的位置我可以打开位置 A到B 的谷歌地图，但无法打开 A到B，C ，d 即可。我怎么能这样做我试过这个

NSString *str1 =[NSString stringWithFormat:@"http://maps.google.com/?saddr=%@&daddr=%@&waypoints=%@&key=%@",originString,destinationString,strWayPoints,GOOGLE_API_KEY];
if([[UIApplication sharedApplication] canOpenURL:
    [NSURL URLWithString:@"comgooglemaps://"]])
{
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str1]];
}
//str1 =
http://maps.google.com/?saddr=18.518205,73.857431&daddr=18.518205,73.857431&waypoints=via:18.518205,73.857431|via:18.552248,73.901596|via:18.629764,73.934685&key=MYKEY

您应该使用提供通用跨平台语法的Google Maps URLs来在移动应用或Google地图网站中打开地图。

在路线模式中，您可以指定路线的起点，终点和多个航路点。有关更多详细信息，请查看以下页面：

https://developers.google.com/maps/documentation/urls/guide#directions-action

网址示例：

TypeError: __WEBPACK_IMPORTED_MODULE_2_rxjs_Observable__.Observable.throw is not a function at CatchSubscriber.webpackJsonp.../../../../../src/app/common/services/search.data.service.ts.SearchDataService.handleError [as selector] (search.data.service.ts:52) at CatchSubscriber.webpackJsonp.../../../../rxjs/operator/catch.js.CatchSubscriber.error (catch.js:104) at XMLHttpRequest.onLoad (http.es5.js:1231) at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:424) at Object.onInvokeTask (core.es5.js:3881) at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:423) at Zone.webpackJsonp.../../../../zone.js/dist/zone.js.Zone.runTask (zone.js:191) at ZoneTask.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneTask.invokeTask [as invoke] (zone.js:498) at invokeTask (zone.js:1370) at XMLHttpRequest.globalZoneAwareCallback (zone.js:1388)

我希望这有帮助！

这是现在正好用于获取方向的代码。我在这里回答，以便其他人知道如何使用它

- (IBAction)onClickNavigate:(id)sender {

NSString *strWayPoints = [NSString stringWithFormat:@"%f,%f", [[destLatArray objectAtIndex:0] doubleValue], [[destLongArray objectAtIndex:0] doubleValue]];
for(int j=0;j<destLatArray.count;j++){
    if(j > 0)
        strWayPoints = [NSString stringWithFormat:@"%@|%f,%f", strWayPoints, [[destLatArray objectAtIndex:j] doubleValue], [[destLongArray objectAtIndex:j] doubleValue]];

}
NSString *originString = [NSString stringWithFormat:@"%f,%f",[sourceLat doubleValue], [sourceLong doubleValue]];
NSString *destinationString = [NSString stringWithFormat:@"%f,%f", [[destLatArray objectAtIndex:0] doubleValue], [[destLongArray objectAtIndex:0] doubleValue]];

NSString *str = [NSString stringWithFormat:@"https://www.google.com/maps/dir/?api=1&origin=%@&destination=%@&waypoints=%@",originString,destinationString,strWayPoints];

if([[UIApplication sharedApplication] canOpenURL:
    [NSURL URLWithString:@"comgooglemaps://"]])
{
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
}
else
{
    NSLog(@"You haven't installed the google map");
}

}

使用Objective c ios在谷歌地图中打开多个站点的方向
