Does Pinterests iPhone app use UIWebViews

From Apple's guide in Support Universal Links:

When you support universal links, iOS 9 users can tap a link to your website and get seamlessly redirected to your installed app without going through Safari. If your app isn’t installed, tapping a link to your website opens your website in Safari.

But i'm confused that if my app is not installed,and I tap a universal link of my app in another app's UIWebView,will the system launch Safari app to load my website,or still load it in the UIWebView?

I test some app's universal links when the app is not installed,and they never launch Safari to load the next page ,they still load it in the UIWebView.

I want to konw if it's possible to launch Safari,but not stay in UIWebView.Do I need any configuration in file?

Actually I want to trace where my app was installed from by using cookie.I can store a cookie in Safari with informations of the download page,and get the cookie with when my app is installed and opened,and present different views according to the cookie.
