ios - 带有 URL Scheme 的谷歌地图？

Question

我正在尝试使用谷歌地图获取方向。我正在关注此链接 https://developers.google.com/maps/documentation/ios-sdk/urlscheme?hl=en

和代码:

if ([[UIApplication sharedApplication] canOpenURL:
         [NSURL URLWithString:@"comgooglemaps://"]]) {
        NSString *temp=@"comgooglemaps://?saddr=Google+Inc,+8th+Avenue,+New+York,+NY&daddr=John+F.+Kennedy+International+Airport,+Van+Wyck+Expressway,+Jamaica,+New+York&directionsmode=transit";

        [[UIApplication sharedApplication] openURL:
         [NSURL URLWithString:temp]];
    } else {
        NSLog(@"Can't use comgooglemaps://");
    }

map 没有打开，我得到:

Installation[2918:1295695] -canOpenURL: failed for URL: "comgooglemaps://" - error: "(null)"

问题是什么？我错过了什么吗？

我想在我的应用程序中显示谷歌地图。

In iOS 9 you must whitelist any URL schemes your App wants to query in Info.plist under the LSApplicationQueriesSchemes key (an array of strings):
