From your code , try this thinks..

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    host = [defaults stringForKey:@"meter_preference"];
    if(!host == nil)
    {
        host = @"10.20.20.1";
        DDLogError(@"Meter host is nil from NSUserDefaults, defaulting to %@", host);
    }

I got the solution, just call the below code in applicationDidFinishLaunchingWithOptions to initialize User defaults. and it works

Replace somePropertyYouExpect in first line with property you stored in User Defaults.

if (![[NSUserDefaults standardUserDefaults] objectForKey:@"somePropertyYouExpect"])  {

    NSString  *mainBundlePath = [[NSBundle mainBundle] bundlePath];
    NSString  *settingsPropertyListPath = [mainBundlePath
                                           stringByAppendingPathComponent:@"Settings.bundle/Root.plist"];

    NSDictionary *settingsPropertyList = [NSDictionary 
                                          dictionaryWithContentsOfFile:settingsPropertyListPath];

    NSMutableArray      *preferenceArray = [settingsPropertyList objectForKey:@"PreferenceSpecifiers"];
    NSMutableDictionary *registerableDictionary = [NSMutableDictionary dictionary];

    for (int i = 0; i < [preferenceArray count]; i++)  { 
        NSString  *key = [[preferenceArray objectAtIndex:i] objectForKey:@"Key"];

        if (key)  {
            id  value = [[preferenceArray objectAtIndex:i] objectForKey:@"DefaultValue"];
            [registerableDictionary setObject:value forKey:key];
        }
    }

    [[NSUserDefaults standardUserDefaults] registerDefaults:registerableDictionary]; 
    [[NSUserDefaults standardUserDefaults] synchronize]; 
}
