I want the Links in my E-Mails to open in a 3rd-Party App on iPhones. The Links should also be openable on any computer.
The Links are normal http/https URLs. I am aware of the concept of custom url schemes on iOS. But links with 'myscheme://' in mails won't work on a computer. The normal approach is to open the website and let it detect if the device is an iPhone and redirect to the url scheme. Problem in this case: Safari won't work on these iPhones. (No way around) Everything happens in an intranet.
Is there a way to register an URL Scheme like Apple Maps does? This is Enterprise Development, so no App Store Review.
