Opening iOS app from Salesforce1 App (v7.3.1)

Question

I'm trying to open custom url scheme iOS app from Salesforce1 app. Previously it was opening fine but since v7.3.1 release i cannot open external app anymore.

Instead of opening app it opens Salesforce1 page with error text:

you can't view this page, either because you don't have permission or because the page isn't supported on mobile devices.

Tried this solution: https://salesforce.stackexchange.com/a/30368/24640

Prevous version of salesforce was working fine when using:

window.top.location = 'myapp://'

and

iframe.src = 'myapp://'

At the moment I'm not sure than if this is bug or salesforce changed something.

Answer 1

I've managed to run app using a bit different link:

window.top.location = 'myapp://home';

It need to be something after schema and before query string like in my example.

I think salesforce1 is validating a link and if it's empty after schema it throws an error.

Answer 2

Just added target="_blank" to my URL and the app pulls up again.
