[ iOS ] 分段控制（Segmented Control）鈕簡易教學

1.建立專案，規劃一個Segmented Control及Label兩個UI物件，並建立Outlet連結。

2.輸入程式

以下為DLIViewControl.h的程式列表；

#import

@interface DLIViewController : UIViewController

@property (strong, nonatomic) IBOutlet UILabel *result;

@property (strong, nonatomic) IBOutlet UISegmentedControl *segmentControl;

- (IBAction)valueChanged:(id)sender;

@end

以下為DLIViewControl.m的程式列表；

#import "DLIViewController.h"

@interface DLIViewController ()

@end

@implementation DLIViewController

@synthesize result;

@synthesize segmentControl;

- (void)viewDidLoad

{

    [super viewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

}

- (void)didReceiveMemoryWarning

{

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

- (IBAction)valueChanged:(id)sender {

    switch (segmentControl.selectedSegmentIndex) {

        case 0:

            [result setText: @"First"];

            break;

        case 1:

            [result setText: @"Second"];

        default:

            break;

    }

}

@end
