iphone - Tracking Application Usage in iOS and logging to file -

i developing sdk ios. help developers utilize our service placing button in 1 of screen. more that, providing analytics. in website, can provide javascript snippet, help track usage , log analytics. developers can place in template used universally (like in footer.html) , forget it. ideal approach same in ios. developers init our service appdelegate or 1 point , should track usage. info track are

user's id,app version, app id, etc. (can collected @ point library inited) usage time (time app opened went background, 1 time again can tracked easily) viewcontrollers loaded , loaded (couldn't find solution unless developer extend viewcontroller our class, or write category. need improve solution in aop) button clicks (same 3rd point)

for these, if provide solution phone call [ourlibrary passflag:viewcontrollerloaded withviewcontroller:self] help it. don't want developers explicitly.

idea have our integration easy possible developers. ideas folks?
