Perform Segue Programmatically Without Button Conn

问题:

I have two view controllers in my storyboard and I need to push from view 1 to view 2.

I need to do this without connecting a segue directly from a button in my storyboard, I need to do it programatically.

How can I?

Thanks.

回答1:

When you click the button call:

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

You will need to create the segue in the storyboard but you can do it from view controller to view controller instead of button to viewcontroller.

回答2:

If you want to perform an action without click (or while loading the viewController itself), do this code in either

- (void)viewDidLoad {
[super viewDidLoad];
[self performSegueWithIdentifier:@"NameOfYourSequeIdentifier" sender:self];
 }

or

-(void)viewDidAppear:(BOOL)animated {
[self performSegueWithIdentifier:@"NameOfYourSequeIdentifier" sender:self];
}

Completely w/o segues

[self.navigationController pushViewController:[self.storyboard instantiateViewControllerWithIdentifier:@"YourViewControllerIDinStoryBoard"] animated:YES];
