[flurryapi logevent:@"event_name"]; 

use logevent count number of times events happen during session of application. can useful measuring how users perform various actions

[flurryapi logallpageviews:navigationcontroller]; 

to enable flurry agent automatically detect , log page view, pass in instance of uinavigationcontroller or uitabbarcontroller logallpageviews. flurry agent create delegate on object detect user interactions. each detected user interaction automatically logged page view. each instance needs passed flurry agent once. multiple uinavigationcontroller or uitabbarcontroller instances can passed flurry agent

[flurryapi setsessionreportsoncloseenabled:(bool)sendsessionreportsonclose]; 

this option on default. when enabled, flurry attempt send session data when app exited when app started. improve speed @ application analytics updated can prolong app termination process due network latency. in cases, network latency can cause app crash.
