iOS Application Update Test -

is there method though wants test when application updated?

i embarrassed because there bug occurs when application updated, , doesn't investigate.

if asking if want find when application updated through app store, not aware of such method.

a hackie approach save current app version nsuserdefaults, check if nsuserdefaults app version equal current app version.

for example:

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {      nsstring *currentappversion = [[[nsbundle mainbundle] infodictionary] objectforkey:@"cfbundleversion"];      if ([defaults objectforkey:@"savedappversionkey"] != nil) {         //key exists          nsstring *savedappversion = [[nsuserdefaults standarduserdefaults] objectforkey:@"savedappversionkey"];          if ([currentappversion isequaltostring:savedappversion]) {             //still running same app version         }         else {             //the app version changed last launch         }      }     else {         //first run, set key & synchronize         [[nsuserdefaults standarduserdefaults] setobject:currentappversion forkey:@"savedappversionkey"];          [[nsuserdefaults standarduserdefaults] synchronize]      }  } 

i haven't tested code, should work.

thanks,
