Question

I have a simple view controller with a few buttons that are defined as IBActions. I want to place them on a scroll view, basically making the whole page scrollable (let’s say they are really big buttons and I have a bunch of them). How can I do that? I tried to add those buttons, but since they are defined as IBAction it did not work.

Here is some of my code. thanks!

- (IBAction) switchFromThird : (id)sender
{
    //some action...
}

- (IBAction) BackHome : (id)sender
{
     //some action...   
}

- (void)viewDidLoad
{
     [super viewDidLoad];    

myScroll.contentSize = CGSizeMake(480, 1000);
myScroll.maximumZoomScale = 4.0;
myScroll.minimumZoomScale = 1.0;
myScroll.clipsToBounds = YES;
myScroll.delegate = self;


[myScroll addSubview:switchFromThird]; //???
[myScroll addSubview:BackHome]; //???


[myScroll release];
}

No, no, no.

Please read this article in iOS Developer Library. You can’t add a method (function) to a view! It’s like you wanted to have a computer program in your printed document on a sheet of paper!

You should do something like this:

1. Write IBOutlet UIButton *BackHomeButton in your .h file.
2. Open your .xib file.
3. Connect the BackHomeButton outlet to your button
4. Replace [myScroll addSubview:BackHome]; with [myScroll addSubview:BackHomeButton];.

Then, and only then it will work. As I said: you can print only images and text, not computer programs!
