ios - - (void)applicationWillEnterForeground: -

maybe assist me.

when app launched first time uialertcontroller message appears , asks user if need goto settings app. using following code.

 dispatch_async(dispatch_get_main_queue(), ^{             [[uiapplication sharedapplication] openurl:[nsurl urlwithstring:@"prefs:root=wi-fi"]];         }); 

upon return app same uialertcontroller message appears, using code in viewdidload:

-(void)viewdidload {   if (launched == no) {      launched = yes;      defaults = [nsuserdefaults standarduserdefaults];     [defaults setbool:launched forkey:@"boolkey"];     [defaults synchronize];      code uialertcontroller.     } else if (launched == yes) {     [self dosomething];   }  } 

it appears bool value not being saved when settings in info.plist application not run in background: set yes, if application not run in background: set no else statement executed. not because app suspended , when launched again need original message appear , not, app restored last state.

any suggestions appreciated.

1.- saving nsuserdefaults not save info.plist. nsuserdefaults has own plist gets wiped out if remove application.

if want prevent launch same alertview:

nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults]; if([defaults boolforkey:@"boolkey"]) {     defaults = [nsuserdefaults standarduserdefaults];     [defaults setbool:yes forkey:@"boolkey"];     code uialertcontroller. } else {      //whatever need if not first launch } 

now next time hit viewdidload, since boolforkey:@"boolkey" has yes, won't hit code , alertview won't presented.
