What is the default time taken while navigating from for view to another view in IOS

Question

I need a small clarification, I've 2 UIViewControllers on pressing on a button from one viewcontroller,I need to navigate to other. But I need to know what is the time taken internally by this UIViewContoller, when we call some this like this.

MyViewController *ins = [[MyViewController alloc]init];
[self.navigationController pushViewController:ins animated:YES];

We all know if that "animated" if "YES" then it will take some time , I need that time or help me in calculating that time.

Answer 1

Not sure why have this question, but I did a small demo to verify this -

Without animation -

Printed timeframe before push - 05/03/2017 11:07:35.7480

Printed timeframe after push - 05/03/2017 11:07:35.7550

With animation -

Printed timeframe before push - 05/03/2017 11:09:42.9680

Printed timeframe after push - 05/03/2017 11:09:42.9760

@IBAction func buttonTapped(_ sender: Any) {
    let bVC = AHBViewController()
    bVC.view.backgroundColor = UIColor.blue
    let startDate = Date()
    print(dateFormatter.string(from: startDate))
    self.navigationController?.pushViewController(bVC, animated: true)
    let endDate = Date()
    print(dateFormatter.string(from: endDate))

}
