Problems when loading another UIView - iphone

Question

In my app, I implemented a QR code reader that directs the app user to another View in the app after scanning any QR code.
I have two Xibs. One is the main screen that loads up when opening the app called demoViewController. The other is the page the app takes you to after scanning a QR code, called yViewController.
On yViewController, I masked the entire page using a UIView called sPage. The reason why I created this UIView is because I needed to implement this code:
[[NSBundle mainBundle] loadNibNamed:#"yViewController" owner:self options:nil];
[self.view addSubview:sPage];
Thats code that takes the user to the second page after scanning. I needed the mask UIView sPage in order to make this method work. And it does work.
However, I think this is screwing up my interface. I had a UIImageView in my sPage View implemented via the
demoViewConroller.m using viewDidLoad:
[topImage setImage: [UIImage imageNamed:#"ylogoREAL.png"]];
The image does not show up.
Additionally, I have some code to animate my view when the keyboard comes up and hides a textfield. This also does not work.
I know the hierarchy is right, because I use a buttonPressed method that works on the sPage View, as well as a method that closes the keyboard when touching the view. But nothing else works.
Can anyone help me figure out why? Im so confused :(

Answer 1

If I understand your error correctly you are calling a function and then ending the line with a semi-colon (programmers force of habit) then going to the next line (maybe) to open the function with a curly bracket.
-(void) function();
{
It needs to not have the semicolon
-(void) function()
{

I'm a bit confused as to what you're trying to achieve, but I'll give it a go
How do you initialize yViewController? I believe you should be using
yViewController = [[UIViewController alloc] initWithNibName:#"yViewController" bundle:[NSBundle mainBundle]];
instead of creating that mask view which loads up yViewController's nib.
Update:
After looking at your code, I believe you want to show a survey page after scanning is done. There are two things you can do
Option 1 - Easier
Present a UIView to the user, using your existing UIViewController (yViewController)
NSArray *nibs = [[NSBundle mainBundle] loadNibNamed:#"Survey" owner:self options:nil];
UIView *view_to_show = [nibs objectAtIndex:0];
[self.view addSubview:view_to_show];
Bear in mind that to be able to dismiss this view later, you will need a reference to it (declare it as a property) and later you can just do [view_to_show setHidden:YES]; or removeFromSuperview
Option 2 - UIViewController option
Create a new UIViewController with your survey view and show that
UIViewController *vc_new = [[UIViewController alloc] initWithNibName:#"Survey" bundle:[NSBundle mainBundle]];
[self presentViewController:vc_new animated:YES completion:nil];

All I needed to do was declare the topImage right under [[NSBundle mainBundle] loadNibNamed:#"yViewController" owner:self options:nil]; . I guess ViewDidLoad was the wrong place to put it in this case!
