使用NSUserDefaults存储对象(值),您可以在任何地方访问它.

AppDelegate(setValue):

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
     [[NSUserDefaults standardUserDefaults] setObject: token forKey:@"deviceID"];
     [[NSUserDefaults standardUserDefaults]synchronize];
}

UIViewController(getValue):

[[NSUserDefaults standardUserDefaults] objectForKey:@"deviceID"];
