How I can Track application spend Time in objective c

Question

I want to track all Application usage time and all the link those I am open in safari Browser.

Is that Feasible in iOS or not?

Answer 1

If by "all application usage time" you mean time that a user spends using apps other than your own on their device, then no. iOS is secure by design and explicitly prevents apps being able to fish around or track what a user is doing outside their own sandbox. The same goes for tracking links.

If you mean tracking usage in your apps, then the answer is of course yes because now you're simply talking about analytics; there are numerous programmatic and third-party ways.
