Adding nib breaks PullableView

[bugs181]

The following code adds a nib view to PullableView however it does not function after.

For example:

UILabel *pullUpLabel;
pullUpLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 4, 320, 20)];
pullUpLabel.textAlignment = UITextAlignmentCenter;
pullUpLabel.backgroundColor = [UIColor clearColor];
pullUpLabel.textColor = [UIColor lightGrayColor];
pullUpLabel.text = @"Pull me up!";

[pullUpView addSubview:pullUpLabel];

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 30)];
label = [[UILabel alloc] initWithFrame:CGRectMake(0, 80, 320, 64)];
label.textAlignment = UITextAlignmentCenter;
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor whiteColor];
label.shadowColor = [UIColor blackColor];
label.shadowOffset = CGSizeMake(1, 1);
label.text = @"I only go half-way up!";

[pullUpView addSubview:label];  

NSArray *subviewArray = [[NSBundle mainBundle] loadNibNamed:@"advanced_search" owner:self options:nil ];
UIView *mainView = [subviewArray objectAtIndex:0 ];
mainView.backgroundColor = [UIColor colorWithWhite:0.0 alpha:0.0];
mainView.opaque = NO;

[pullUpView addSubview:mainView];

Commenting out the last line will make it work again:
[pullUpView addSubview:mainView];

Could you please provide more information? What do you mean by "does not function"? What is included in this Nib that is being loaded?

[bugs181]

At the moment, the nib is a blank UIView which will later contain components like a UITableView. "Does not function" means that after adding the UIView ([pullUpView addSubview:mainView];) will make it to where you can't do anything with pullUpView. IE. Tapping or pulling on the Pull me Up! label does nothing. It seems that it's just locked in place. Sorry for not explaining more thoroughly.

Oh, it should also be noted that Automatic Reference Counting is turned on and iOS Deployment Target is set to 7.0. Everything works as intended until I add the mainView to the subView.
