ios - 如何在 google map 中使用起点和终点之间的 url 和参数创建路线？

Question

我想在网络中打开一个url 并自动在两点之间创建一条路线。我在 google map 文档中找不到正确的 url 和参数。

Answer 1

对于 Swift 4 和 Swift 5

let apiKey = "https://www.google.com/maps/dir/" + userCurrentLocation.coordinate.latitude + "," + userCurrentLocation.coordinate.longitude + "/" + nextCurrentLocation.coordinate.latitude + "," + nextCurrentLocation.coordinate.longitude
                
    var url = URL(string: apikey)

对于 objective-c 使用

   NSString *apikey = [NSString stringWithFormat:@"https://www.google.co.in/maps/dir/%f,%f/%f,%f",userCurrentLocation.coordinate.latitude,userCurrentLocation.coordinate.longitude,nextCurrentLocation.coordinate.latitude,nextCurrentLocation.coordinate.longitude;

NSURL *url = [NSURL URLWithString:apikey];

[[UIApplication sharedApplication] openURL:url];
