Question

I know that NSUserDefaults can read the key and value from plist file.
Is it possible to read the structure of a key?

For example:

Key ‘Count’ is an integer and has option
1,2,3,4,5

the codes below can get the value ‘Count’

NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];

if([defaults objectForKey:@"Count"]!=nil)
{

    NSString *s=[[NSString alloc] initWithString: [defaults objectForKey:@"Count"]];
    NSInteger v=[s intValue];
    [s release];
}

But I prefer to get all options and store to a NSArray or a better storage structure.

Is it Possible?

I read bundle settings the following way:

// Get path to Root.plist file in settings bundle and retrieving its contents
NSString* tPath = [[NSBundle mainBundle] pathForResource:@"Settings" ofType:@"bundle"];
settingsBundle = [[NSBundle bundleWithPath:tPath] retain];
NSDictionary* tSetDict = [NSDictionary dictionaryWithContentsOfFile:[tPath stringByAppendingPathComponent:@"Root.plist"]];

// Get array of preference dictionaries 
NSArray* prefs = [tSetDict objectForKey:@"PreferenceSpecifiers"];

// Iterate through dictionaries to find required value
for (NSDictionary* setDict in prefs){
    NSString* type = [setDict objectForKey:@"Type"];
    if (![type isEqualToString:@"PSMultiValueSpecifier"]){
        // Get possible preference values for PSMultiValueSpecifier case
        // You may need to know value type in advance - not sure about that
        NSArray* values = [setDict objectForKey:@"Values"];
    }
}
