you can put in - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions:

if (![[nsuserdefaults standarduserdefaults] boolforkey:@"applicationrunbefore"]) {     [[nsuserdefaults standarduserdefaults] setbool:yes forkey:@"applicationrunbefore"];     [[nsuserdefaults standarduserdefaults] synchronize];     // application running first time -     ... }
