I can get how many downloading counts by iTunes Connect, but there is info about which iOS version to download, how can know that information in simple way?
Yes, that is what I want to know.You mean which iOS version the people who bought your app have? No, you need to use some sort of analytics in your app to know who uses what.
Yes, that is what I want to know.
So you mean I have to collect such info by my app no any way else?
How can I do it? Can you give me some detail suggestion or sample?Right. You have to collect it yourself. There is no "built-in" way to know which iOS version your users are running.
Thanks for your info, I will try it.Google Analytics, not that hard.
You sign up for free, download their files, put them in your project, and each step you want to track, you can send to GA with some really easy code.
[GATracker trackPage"iphone/page1"]; something like that, i don't have any projects open, but it's to give an example. On each VC you want to trigger these tracks, you can do that, you can check how many active users etc.
Also, you can trigger things like you want in the appdelegate for example, when you start tracking, is to send the info to GA, not sure if this is build in, or you need to use some DeviceHW identifier component to check & send it to GA yourself.
