Setting bundle default value won't set

Question

I have an iOS application with a settings.bundle that handles various settings for my application with Switch toggle. I set default values in my root.plist file

Answer 1

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //< Register Defaults
    NSString *settingsBundlePath = [[NSBundle mainBundle] pathForResource:@"Settings" ofType:@"bundle"];
    NSBundle *settingsBundle = [NSBundle bundleWithPath:settingsBundlePath];
    NSString *rootPlistPath = [settingsBundle pathForResource:@"Root" ofType:@"plist"];
    NSDictionary *settingsDict = [[NSDictionary alloc] initWithContentsOfFile:rootPlistPath];
    NSArray *settingsItems = [settingsDict objectForKey:@"PreferenceSpecifiers"];
    NSMutableDictionary *defaultDict = [NSMutableDictionary new];
    for (NSDictionary *itemDict in settingsItems) {
        if ([itemDict objectForKey:@"DefaultValue"]) {
            [defaultDict setObject:[itemDict objectForKey:@"DefaultValue"] forKey:[itemDict objectForKey:@"Key"]];
        }
    }
    [[NSUserDefaults standardUserDefaults] registerDefaults:defaultDict];
    //< Following Code
}
