[FlurryAPI logEvent:@"EVENT_NAME"];

Use logEvent to count the number of times certain events happen during a session of your application. This can be useful for measuring how often users perform various actions

[FlurryAPI logAllPageViews:navigationController];

To enable Flurry agent to automatically detect and log page view, pass in an instance of UINavigationController or UITabBarController to logAllPageViews. Flurry agent will create a delegate on your object to detect user interactions. Each detected user interaction will automatically be logged as a page view. Each instance needs to only be passed to Flurry agent once. Multiple UINavigationController or UITabBarController instances can be passed to Flurry agent

[FlurryAPI setSessionReportsOnCloseEnabled:(BOOL)sendSessionReportsOnClose];

This option is on by default. When enabled, Flurry will attempt to send session data when the app is exited as well as it normally does when the app is started. This will improve the speed at which your application analytics are updated but can prolong the app termination process due to network latency. In some cases, the network latency can cause the app to crash.
