即使我的iOS设备中没有Google地图，“ canOpenURL”也返回true？

Question

I have GoogleMaps SDK in my app but don't have google maps iOS app in my device but still UIApplication.shared.canOpenURL(URL(string:"comgooglemaps://")!) returns true instead of false .

How can I handle this problem?

Any Help.

Answer 1

yes. it can.

if ANY installed app claims it can handle the url scheme 'comgooglemaps'

there is no 1 to 1 fixed relationship for urls to apps. any app(s) can claim any protocol

you cant really avoid this im afraid. not if you use urls. you can look at DocumentControllers or ActivityItems to share with user interaction
