How to pass prepareForSegue programmatically an objected created programmatically - objective-c

Question

i have a loop in which i create buttons with a selector calling a prepareForSegue. I would pass to the next page the image of the button i clicked.
for (i = 1; i <= 22; i++) //22 it's just temporary
{
//creating button
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self
action:#selector(nextPage: )
forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"" forState:UIControlStateNormal];
button.frame = CGRectMake(X, Y, 100.0, 100.0);
UIImage *buttonImageNormal = [UIImage imageNamed:#"ambient.png"];
//image obviously will be different and i want to pass that
[button setBackgroundImage:buttonImageNormal forState:UIControlStateNormal];
if (i%3==0 && i==0)
X = 20;
if (i%3==0 && i!=0){
X = 20;
Y = Y+150;
}
if (i%3==1)
X = 140;
if (i%3==2)
X = 260;
[_scroll addSubview:button];
}
this is the method called by every button
-(void)nextPage:(id)sender {
UIViewController *myController = [self.storyboard instantiateViewControllerWithIdentifier:#"signSegue"];
[self.navigationController pushViewController: myController animated:YES];
}
and this is the prepareForSegue
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
addController *controller = (addController *)segue.destinationViewController;
}
what i have to pass with controller?

Answer 1

You should not be calling prepareForSegue directly. Instead, you should trigger your segue programmatically, letting the framework take care of calling prepareForSegue in the due course:
[self performSegueWithIdentifier:#"mySegue" sender:self];

Answer 2

You can do like following
-(void)nextPage:(id)sender {
UIButton *pressedButton=(UIButton *)sender;
SecondViewController *myController = [self.storyboard instantiateViewControllerWithIdentifier:#"SecondViewController"];
myController.pressedButtonImageName=pressedButton.currentBackgroundImage;
[self.navigationController pushViewController: myController animated:YES];
}
in your second VC :
#property (nonatomic,strong) UIImage *pressedButtonImageName;
Here, you dont need to do anything with prepareForSegue method.
