Opening viewController programmatically in swift
提问by Manu Gupta
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?

To open New view controller you need to write this line in button click event:
要打开新视图控制器，您需要在按钮单击事件中编写此行：
self.performSegueWithIdentifier("GoToViewController", sender:self)
To link up with new view controller follow this steps:
要与新的视图控制器链接，请按照以下步骤操作：
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
从情节提要中选择新视图控制器并右键单击它
您会发现将出现 Dark dray 弹出窗口（见图）
现在在 Presenting Segues 下选择 Present Modally 并从您需要打开此视图控制器并链接它的位置拖动到视图控制器
你会发现在新视图控制器下创建了新的 segue
现在选择那个 segue 转到检查器并复制标识符或重命名并复制它
在上面的行中使用该标识符
Hope it will work.
希望它会起作用。

我想将我的视图控制器添加到导航控制器，这也有效
