Question

I’m aware of NSUserDefaults for saving/restoring user preferences. What is the equivalent class for an application? For example, the application may have a “last run” field; or it may have a field for a unique identification of the device for use at the application level.

My intention is to keep the application’s settings (not user’s settings) out of the Settings Application, and not backup those settings in iTunes, Time Machine, {whatever}.

I’m getting a lot of noise for Java and C#, but not much for iOS/iPhone/iPad.

if you can store value by NSUserDefaults, then it is good to store application preferences too.

or add settings.plist on your project and read that (what you are not changing later)

and you can use like.,

+ (NSDictionary*)getBundlePlist:(NSString *)plistName
{
    NSString *errorDesc = nil;
    NSPropertyListFormat format;
    NSString *plistPath = [[NSBundle mainBundle] pathForResource:plistName ofType:@"plist"];
    NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];
    NSDictionary *temp = (NSDictionary *)[NSPropertyListSerialization
                                          propertyListFromData:plistXML
                                          mutabilityOption:NSPropertyListMutableContainersAndLeaves           
                                          format:&format errorDescription:&errorDesc];
    return temp;
}

+ (id) getPropValue:(NSString *)PropertyName
{   // I am supposing you had add your app preferences on settings.plist.
    return [[Property getBundlePlist:@"settings"] objectForKey:PropertyName];
    //here Property is my class name, then you can use value by 
    //NSString *value = [Property getPropValue:@"setting1"];
}
