Creating delegates

gistfile1.txt

In Klasse die das delegate erhalten soll:

  @protocol CustomAlertDelegate <NSObject>

    -(void)dismissMyViewController:(UIViewController *)aViewController;

  @end

define the delegate property:

  @property (strong, nonatomic) id<CustomAlertDelegate> myDelegate;

inside the implementation of this Class, to check if the button has been delegated:

- (IBAction)btBottom:(id)sender{

  if([_myDelegate respondsToSelector:@selector(dismissMyViewController:)]){

    [_myDelegate dismissMyViewController:self];
  }
}

Add delegate Methods (from protocol) into the class you want to delegate from:

-(void)dismissMyViewController:(UIViewController *)aViewController{

  // what should happen after delegation
}

and set the delegate to the class you want to delegate from:

init class
initClass.myDelegate = self;
