Question

In iOS,I would like to include both a delegate for the flipsideView (from a Utility Application template) and a delegate to allow to scroll the view.
My attempt, which does not work, is:

@interface MainViewController : UIViewController 
<FlipsideViewControllerDelegate> <UIScrollViewDelegate> {
 }

I tried to place a comma (,) or a space between the two <>, but it does not work.
Would someone be able and willing to help me concerning this question?

Thank you in advance for your help

Answer 1

Do it this way:

@interface MainViewController : UIViewController 
  <FlipsideViewControllerDelegate, UIScrollViewDelegate> 
{

}

The syntax is as follows:

@interface ClassName : ItsSuperclass <
protocol list >

For example for multiple protocols:

@interface Formatter : NSObject <
Formatting, Prettifying >

You can read more on protocols and how to adopt and conform in Apple’s official Documentation.
