Create directory programmatically

Question

I want to create a directory inside my applicationSupportDirectory. My understanding is that the applicationSupportDirectory does not allow users to see the data within. This is why I have chosen it. However, the code I am using below seems to fail and I am not sure why.

Can anyone tell me what I have done wrong? Thanks!

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory,   NSUserDomainMask, YES);
NSString *applicationDirectory = [paths objectAtIndex:0]; // Get directory
NSString *dataPath = [applicationDirectory stringByAppendingPathComponent:@"drawings"];

if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath]){

NSError* error;
if([[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error])
  ;// success
else
{
  NSLog(@"Failed");
}
}
}

Try this one, it works for me.

NSString* documentsPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                              NSUserDomainMask,
                                                              YES)[0];
NSString *folder = [documentsPath stringByAppendingPathComponent:@"foldername"];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error = nil;
if (![fileManager fileExistsAtPath:folder]){
    [fileManager createDirectoryAtPath:folder
           withIntermediateDirectories:YES
                            attributes:nil
                                 error:&error];
}
