Answer 1

此处说明导航模式，＆＃34;向您的应用添加导航＆＃34; ：https://developers.google.com/maps/documentation/ios-sdk/urlscheme

试试这段代码：

NSURL *testURL = [NSURL URLWithString:@"comgooglemaps-x-callback://"];
if ([[UIApplication sharedApplication] canOpenURL:testURL]) {
  NSString *directionsRequest = @"comgooglemaps-x-callback://" + @"?daddr=John+F.+Kennedy+International+Airport,+Van+Wyck+Expressway,+Jamaica,+New+York" + @"&x-success=sourceapp://?resume=true&x-source=AirApp";
  NSURL *directionsURL = [NSURL URLWithString:directionsRequest];
  [[UIApplication sharedApplication] openURL:directionsURL];
}
