Coding a Popover segue for a custom UIButton - iphone

Question

I have a custom UIButton which I defined programmatically like this:
self.hard1 = [UIButton buttonWithType:UIButtonTypeCustom];
[self.hard1 setFrame:CGRectMake(884, 524, 105, 60)]; // set the x,y,width and height
UIImage *buttonImage = [UIImage imageNamed:#"green.jpg"];
self.hard1.layer.cornerRadius = 10;
self.hard1.clipsToBounds = YES;
[self.hard1 addTarget: self
action: #selector(buttonTapped:)
forControlEvents: UIControlEventTouchUpInside];
[self.hard1 setImage:buttonImage forState:UIControlStateNormal];
[self.view addSubview:self.hard1];
As a result of that, it doesn't show in the Interface Builder, it only comes on the screen when I run the app. This means I can't ctrl + drag from the UIButton to a ViewController to select a popover segue. Can I call a segue within my code? If not, are there any other options for me?

Answer 1

Blub's and tkanzakic's answers won't quite work, as a popover segue insists on having an anchor view in the storyboard when you create the segue. And as your button doesn't yet exist it will be tricky to get that right. You could anchor to an existing storyboard view, but then the popover arrow won't point to the right object when it pops over. You could move that existing view around in code to match the rect of your code-created button. But you might as well dispense with the segue altogether and perform the popover in code.
You will need to declare a popoverController property:
#property (nonatomic, strong) UIPopoverController* buttonPopoverController;
Then your button action can look something like this:
- (void) buttonTapped:(UIButton*) sender
{
ContentViewController* contentVC = [[ContentViewController alloc] init];
self.buttonPopoverController = [[UIPopoverController alloc]
initWithContentViewController:contentVC];
self.buttonPopoverController.delegate = self;
//only required if using delegate methods
[self.buttonPopoverController presentPopoverFromRect:sender.frame
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
The ContentViewController is whichever view controller you are intending to segue to. If it is configured using a storyboard scene, you may want to do something like this when you create it:
UIStoryboard *storyboard = self.storyboard;
ContentViewController* contentVC =
[storyboard instantiateViewControllerWithIdentifier:#"ContentViewController"];
You can set the storyboard identifier using the Identity Inspector when you have the relevant view controller selected in the storyboard.

Answer 2

in the process of creation of the button you are assigning it an action associate to a method called buttonTapped:, you can perform the segue from there, something like this:
- (void)buttonTapped:(id)sender
{
[self performSegueWithIdentifier:#"theSegueIdentifier" sender:sender];
}

Answer 3

CTRL + drag a segue from the ViewController that contains your
Button --> ViewController you want to segue to
Secify an identifier (just some unique string) for that segue (
with the segue selected, open the righthand "Utilities" sidebar
and open it's "Attributes inspector" tab
Add [self
performSegueWithIdentifier:#"identifierStringYouSecifiedInStep2" sender:sender];
inside your - (void)buttonTapped:(id)sender method ! )
