How to open URL schemes from Safari in iOS9?

Question

I was able to open apps from safari this way:

window.location = 'myapp://do/xx';

or open facebook app:

window.location = 'fb://';

But this stopped working in iOS9.

How can I open apps using URL schemes in safari?

Answer 1

IOS 9 URL Shchemes Update : iOS 9 introduces LSApplicationQueriesSchemes to allow apps to query if other apps are installed.

1- If a url scheme is declared and calling canOpenURL(scheme)

YES if a installed app supports that URL scheme

NO if no app supporting that url

syslog will show canOpenURL: failed for URL: "urlScheme://" - error: null

2- If a url scheme is not declared and calling canOpenURL(scheme)

always return NO

syslog will show canOpenURL: failed for URL: "urlScheme://" - error: null

In iOS 9, the developer must add these info.plist LSApplicationQueriesSchemes

<array>
    <string>urlscheme</string>
    <string>urlscheme2</string>
    <string>urlscheme3</string>
    <string>urlscheme4</string>
</array>

50 max. unqiue URL scheme can be declared!
