Question

I know how I can get a button to open a new ViewController(new class) in the storyboard by dragging and dropping. But I need a code that I can write in the .m file that opens a new View when my button is clicked.

In my FirstViewController.m i got:

- (IBAction)button1:(id)sender {

}

What code do i need in this to get the button to open the SecondViewController?

Answer 1

[self performSegueWithIdentifier: @"TheSequeName" sender: self];

The @”TheSequeName” is defined when you ctrl drag a button to open a new view controller on the storyboard

If you don’t use segue, there are many variants to open a new view controller. The basic one is using a separate NIB (without storyboard)

SecondViewController *view = [[SecondViewController allow] initWithNibName:@"NibName" bundle:nil];

If you declare your view controller on Storyboard, you can use

SecondViewController *view = [self.storyboard instantiateViewControllerWithIdentifier:@"viewStoryboardId"]; 

Then you show your SecondViewController using navigation controller

[self.navigationController pushViewController:view animated:YES];

Or as modal view

[self presentModalViewController:view animated:YES];
