UI控件-Segmentarray

用代码创建处Segmentarray控件，并设置它的一些属性：

[cpp] /*segmentarray.h*/

#import <UIKit/UIKit.h>

@interface segmentarray : UIViewController
{
    //创建控件对象
    UISegmentedControl *segment;
}
@property (nonatomic,retain) UISegmentedControl *segment;
@end
/*segmentarray.h*/

#import <UIKit/UIKit.h>

@interface segmentarray : UIViewController
{
//创建控件对象
UISegmentedControl *segment;
}
@property (nonatomic,retain) UISegmentedControl *segment;
@end

在 .m 文件中初始化及设置属性值

[cpp] - (void)viewDidLoad
{
    [super viewDidLoad];

    //建立一个数组，来存放title
    NSArray *Segmentarray = [[NSArray alloc]initWithObjects:@"1",@"2",@"3",@"4",nil];

    //初始化SegmentControl对象，并把title添加进去
    self.segment = [[UISegmentedControl alloc]initWithItems:Segmentarray];

    //使用完后，释放NSArray对象
    [Segmentarray release];

    //定位，设置添加到界面中的位置和它的宽／高
    self.segment.frame = CGRectMake(40, 60, 120, 40);

    //设置控件SegmentControl的风格
    self.segment.segmentedControlStyle = UISegmentedControlStyleBezeled;
    /* 四种控件风格
     UISegmentedControlStylePlain,     // large plain
     UISegmentedControlStyleBordered, // large bordered
     UISegmentedControlStyleBar,       // small button/nav bar style. tintable
     UISegmentedControlStyleBezeled,   // large bezeled style. tintable
     */

    //设置初始的默认值,根据索引值来设置
    self.segment.selectedSegmentIndex = 2;

    //把控件添加到view中
    [self.view addSubview:self.segment];

    //释放SegmentControl对象
    [segment release];
}
