快速以编程方式打开viewController

Question

I want to open new UIViewController on the button through code. I have already made the controller in storyboard and just want to link it and also I don't want to use XIB interface or nibName?

Answer 1

To open New view controller you need to write this line in button click event:

self.performSegueWithIdentifier("GoToViewController", sender:self)

To link up with new view controller follow this steps:

• Select New view controller from storyboard & right click on it

• You will find Dark dray popup will appear (see image )

• Now under Presenting Segues select Present Modally & drag to the View controller from where you need to open up this view controller & link it

• You will find new segue created under New view controller

• Now select that segue go to inspector & copy the identifier or rename & copy it

• Use that identifier in above line

Hope it will work.

Answer 2

self.navigationController!.pushViewController(self.storyboard!.instantiateViewControllerWithIdentifier("userProfileController") as UIViewController, animated: true)

我想将我的视图控制器添加到导航控制器，这也有效

对于Swift 4.2，请尝试以下代码：
