用代碼創建處Segmentarray控件，並設置它的一些屬性：

[cpp] /*segmentarray.h*/ 
 
#import <UIKit/UIKit.h>  
 
@interface segmentarray : UIViewController 
{ 
    //創建控件對象  
    UISegmentedControl *segment; 
} 
@property (nonatomic,retain) UISegmentedControl *segment; 
@end 
/*segmentarray.h*/

#import <UIKit/UIKit.h>

@interface segmentarray : UIViewController
{
    //創建控件對象
    UISegmentedControl *segment;
}
@property (nonatomic,retain) UISegmentedControl *segment;
@end

在  .m  文件中初始化及設置屬性值

[cpp] - (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
     
    //建立一個數組，來存放title  
    NSArray *Segmentarray = [[NSArray alloc]initWithObjects:@"1",@"2",@"3",@"4",nil]; 
     
    //初始化SegmentControl對象，並把title添加進去  
    self.segment = [[UISegmentedControl alloc]initWithItems:Segmentarray]; 
     
    //使用完後，釋放NSArray對象  
    [Segmentarray release]; 
     
    //定位，設置添加到界面中的位置和它的寬／高  
    self.segment.frame = CGRectMake(40, 60, 120, 40); 
     
    //設置控件SegmentControl的風格  
    self.segment.segmentedControlStyle = UISegmentedControlStyleBezeled; 
    /* 四種控件風格
     UISegmentedControlStylePlain,     // large plain
     UISegmentedControlStyleBordered,  // large bordered
     UISegmentedControlStyleBar,       // small button/nav bar style. tintable
     UISegmentedControlStyleBezeled,   // large bezeled style. tintable
     */ 
     
    //設置初始的默認值,根據索引值來設置  
    self.segment.selectedSegmentIndex = 2; 
     
    //把控件添加到view中  
    [self.view addSubview:self.segment]; 
     
    //釋放SegmentControl對象  
    [segment release]; 
}
