Use UIButton to navigate between UIViews

Question

I have programmatically constructed a UIButton in view1 which is currently displayed. The goal is when the button is clicked, view1 will switch to view2. I know how to achieve this by using segue, but since I can't control-drag the UIButton into my .m file, how do I make this work?

Answer 1

Add a target to your button

[myButton addTarget:self 
             action:@selector(myAction) 
   forControlEvents:UIControlEventTouchUpInside];

and then segue

- (void)myAction {
   [self performSegueWithIdentifier:"identifier" sender:nil];
}

Answer 2

[button addTarget:self
           action:@selector(buttonPressed:)
 forControlEvents:UIControlEventTouchUpInside];

then implement a method in that view controller like so: (assign an identifier to the segue in the storyboard)

- (void)buttonPressed:(id)sender
{
    [self performSegueWithIdentifier:@"segueName" sender:nil];
}

or using the identifier of a view controller in the storyboard

- (void)buttonPressed:(id)sender
{
    UIViewController *viewController = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewController"];
    [self presentViewController:viewController animated:YES completion:nil];
}
