How to open third party app on iOS 9?

Question

Objective-C

Example:
When in the VK application in the profile, click on the instagram link, it displays the message "VK" wants to open "Instagram" and opens the profile in the instagram of this person.
Tried to google how to do the same but couldn't find anything.

Answer 1

URL schemes - try to google in this direction. Or the use of exstension from another application can be used for interaction, or if these are two applications of the same manufacturer, they can be combined into one group and use its identifier for interaction.

Answer 2

Also for iOS9, you need to add the LSApplicationQueriesSchemes key to Info.plist with an array of the required Scheme URLs, this is due to the new security policy, you can learn more in the video from WWDC 2015 "Privacy and Your App"
