How to get a link to a control in a view?

Question

If I have a UIScrollView configured in the view via Interface Builder, how can I get a link to it in the ViewController implementation? I want to programmatically add labels to the scroll.

For example, in C #, if you have a text field declared in the user interface / form, you can access it simply by using the identifier declared for this text field. It does not seem so simple in the lens c.

Thanks Kevin

Assuming I understand you correctly, and you create a view controller from .xib containing subviews, including the UIScrollView that you want, there are two ways: first, you can find it in the subviews array that belongs to the view controller. Secondly, you can add a link to IBOutlet in your header file, and then make a connection using the connection inspector in the interface builder. Then you can refer to the object in your code, change the frame, add tags, etc.

You need to connect your ViewController to your Nib files. It is pretty simple. This is your main workflow for using Interface Builder on iPhone / iPad:

• " " . , " " nib, Command-4 .

• :

  @property (, ) IBOutlet UIScrollView * scrollView;

IBOutlet - , . , , , Interface Builder , scrollView .

• , ViewController. , .

- Xcode. - , . !

: , " UIViewController" " ", . nib View Controller, .
