1，选择控件的创建，并监听控件选择值

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

class ViewController : UIViewController {      override func viewDidLoad() {          super .viewDidLoad()            //选项除了文字还可以是图片          var items=[ "选项一" , "选项二" , UIImage (named: "star" )] as [ AnyObject ]          var segmented= UISegmentedControl (items:items)          segmented.center= self .view.center          segmented.selectedSegmentIndex=1 //默认选中第二项                segmented.addTarget( self , action: "segmentDidchange:" ,          forControlEvents: UIControlEvents . ValueChanged )  //添加值改变监听           self .view.addSubview(segmented)      }        func segmentDidchange(segmented: UISegmentedControl ){          //获得选项的索引          println (segmented.selectedSegmentIndex)          //获得选择的文字          println (segmented.titleForSegmentAtIndex(segmented.selectedSegmentIndex))      } }

2，选择控件中选项的添加和删除

1 2 3 4 5 6

//添加文字选项 segmented.insertSegmentWithTitle( "新增选项" ,atIndex:1,animated: true ); //添加图片选项 segmented.insertSegmentWithImage( UIImage (named: "icon" )!,atIndex:1,animated: true ) //移除选项 segmented.removeSegmentAtIndex(1,animated: true );

3，修改选项颜色（包括图片选项）

1	segmented.tintColor= UIColor .redColor()

4，修改选项文字

1	segmented.setTitle( "swfit" ,forSegmentAtIndex:1)

5，修改选项图片

1	segmented.setImage( UIImage (named: "icon" ),forSegmentAtIndex:2)

6，修改选项内容偏移位置

1	segmented.setContentOffset( CGSizeMake (10,7),forSegmentAtIndex:1)
