You have to connect the segmented control to an IBOutletin Interface Builder, then you can write
您必须将分段控件连接到IBOutletInterface Builder中，然后您可以编写
@IBOutlet var entrada : UISegmentedControl!
override func viewDidLoad() {
super.viewDidLoad()
entrada.setTitle("Action 1", forSegmentAtIndex: 0)
entrada.setTitle("Action 2", forSegmentAtIndex: 1)
entrada.setTitle("Action 3", forSegmentAtIndex: 2)
}
In Swift 3+ the syntax has been changed to
在 Swift 3+ 中，语法已更改为
override func viewDidLoad() {
super.viewDidLoad()
entrada.setTitle("Action 1", forSegmentAt: 0)
entrada.setTitle("Action 2", forSegmentAt: 1)
entrada.setTitle("Action 3", forSegmentAt: 2)
}

You can use below code snippet to setup titles of your segment control. Just pass an array of string to set titles.
您可以使用以下代码片段来设置段控件的标题。只需传递一个字符串数组来设置标题。

斯威夫特 4+
func segmentWithTitles(titles : [String]) {
self.friendsSegment.setTitle(titles[0], forSegmentAt: 0)
self.friendsSegment.setTitle(titles[1], forSegmentAt: 1)
self.friendsSegment.setTitle(titles[2], forSegmentAt: 2)
}
