Question

I have one Toggle Switch in my settings bundle, but it is not working for first time. When i changed the value once again in the settings it is working corrctly.

Even i synchronize before using the value:

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];

[userDefaults synchronize];

if([userDefaults boolForKey:@"KeyName"]) {

    //Do Some Work
}

What i have to do now?

I think what you are encountering here is the rather strange issue that the settings in your settings bundle are not loaded until the first time the user runs the settings application.

Straight from Apple:

For newly installed applications,
default preference values from the
application’s Settings bundle are not
set until the Settings application
runs. This means that if the user runs
your application before running
Settings, the default values specified
in your Settings bundle are
unavailable.
