Change application settings through settings bundle while application is running IOS

I have written code in -(void)applicationWillEnterForeground:(UIApplication *)application , but my application is not detecting the change made in the settings bundle, new settings work when application restart开发者_开发问答s, someone please help me how to make changes in application's settings while application is running

Try to -(BOOL)synchronize; the NSUserDefaults.

After setting the values in NSUserDefaults try calling [[NSUserDefaults standardUserDefaults] synchronize]; so that the values get written to disk.

in your applicationWillEnterForeground: methode after this line

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults], add this line

[defaults synchronize];
