Question

我需要学习如何基于if语句转到不同的viewcontroller。我对迅捷是全新的。我已经有了这个 - 当计数器达到5时，我需要它去一个不同的视图。

class ViewController: UIViewController {

    @IBOutlet var countNumber: UILabel!

    var conta = 0


    @IBAction func counterPlus(sender: AnyObject) {

        conta++


        if conta == 5{

         //I WANT TO GO TO A DIFFERENT VIEWCONTROLLER HERE


        }else

        {
            countNumber.text = String(conta)
        }


    }

Answer 1

您可以通过segue或storyboard标识符的方式执行此操作。使用以下代码：

// segue method, also give your segue an identifier in storyboard

if // your statement {
    performSegueWithIdentifier("yourIdentifier")
}

// storyboard identifier method, give your view controller an identifier in storyboard in the "identity inspector"

if // your statement {
    let destinationController = storyboard.instantiateViewControllerWithIdentifier("yourIdentifier")
    presentViewController(destinationController, animated: true, completion: nil)
}

Answer 2

使用

if // your statement { performSegueWithIdentifier（＆＃34; segueOne＆＃34 ;, sender：nil）

}

根据IF语句更改ViewController
