Save file in OS X in a private folder like iOS documents folder

Does OS X have a place within the application to save files like how you save files to the documents folders in iOS. I have .plist files to save for my app but I only want to be able to access them form within the app. Don't want do have a folder in the users documents folder or anything.

Primarily an iOS guy so apologies if this is obvious.

This worked for me:

-(void) setupApp {
    NSString * myAppPath = [[Configurations createApplicationDirectoryWithPathComponent:MY_APP_DIR_NAME] path];
   self.plistPath = [myAppPath stringByAppendingString:CONFIG_FILE_NAME];
   [self createNewConfigFileWithDictionary:yourDictionary];
}

-(void) createNewConfigFileWithDictionary:(NSDictionary*)dictionary {
    @try {
        NSFileManager * fileManager = [NSFileManager defaultManager];
        if (![fileManager fileExistsAtPath:self.plistPath]) {
                [dictionary writeToFile:self.plistPath atomically:YES];
        }
    } @catch (NSException *exception) {
        NSLog(@"[MyClass createNewConfigFileWithDictionary] Problem:%@ Description: %@", [exception name],[exception reason]);
    } @finally {}
}

+ (NSURL*) createApplicationDirectoryWithPathComponent:(NSString*)path {
    NSFileManager*fm = [NSFileManager defaultManager];
    NSURL*    dirPath = nil;
    // Find the application support directory in the home directory.
    NSArray* appSupportDir = [fm URLsForDirectory:NSApplicationSupportDirectory inDomains:NSUserDomainMask];
    if ([appSupportDir count] > 0) {
        // Append the bundle ID to the URL for the
        // Application Support directory
        dirPath = [[appSupportDir objectAtIndex:0] URLByAppendingPathComponent:path];
        // If the directory does not exist, this method creates it.
        // This method is only available in macOS 10.7 and iOS 5.0 or later.
        NSError*    theError = nil;
        if (![fm createDirectoryAtURL:dirPath withIntermediateDirectories:YES attributes:nil error:&theError]) {
            @throw [NSException exceptionWithName:@"CreateApplicationDirectoryWithPathComponentException"
                                           reason:theError.localizedDescription
                                         userInfo:nil];
            return nil;
        }
    }
    return dirPath;
}

I'm not exactly sure what you want here.

To get a directory to store files in an out of the way location, you can use the Application Support directory (~/Library/Application Support/[APP_NAME]/).

To get the name of this directory, you pass NSApplicationSupportDirectory to -URLsForDirectory:inDomains: (see: Managing Files and Directories).

To prevent the user from reading a file, you can encrypt it (see: Encrypting and Hashing Data).
