有三个view，分别为view1、view2、view3，通过UISegmentedControl进行三个view的切换。

Ios代码 ![收藏代码][icon_star.png]

1.  @interface UIViewDemoViewController : UIViewController \{
2.  IBOutlet UIView \*view1;
3.  IBOutlet UIView \*view2;
4.  IBOutlet UIView \*view3;
5.  \}
6.  
7.  \- (IBAction)switchViews:(id)sender;
8.  @end

在Interface Builder中分别建立三个view，关联到各自的输出口，每个view上的UISegmentedControl关联到switchViews:操作。

Ios代码 ![收藏代码][icon_star.png]

1.  \- (void)viewDidLoad \{
2.  \[super viewDidLoad\];
3.  \[self.view addSubview:view1\];
4.  \[self.view addSubview:view2\];
5.  \[self.view addSubview:view3\];
6.  \}
7.  
8.  \- (IBAction)switchViews:(id)sender\{
9.  UISegmentedControl \*segmentedControl = sender;
10. \[\[NSNotificationCenter defaultCenter\] postNotificationName:@"switchViews" object:\[NSNumber numberWithInteger:\[segmentedControl selectedSegmentIndex\]\]\]; 
11. \}

接着，为UISegmentedControl控件建立一个处理类。

Ios代码 ![收藏代码][icon_star.png]

1.  @interface SegmentedControl : UISegmentedControl \{
2.  IBOutlet UIView \*view1;
3.  IBOutlet UIView \*view2;
4.  IBOutlet UIView \*view3;
5.  IBOutlet UIViewDemoViewController\* viewController;
6.  \}
7.  
8.  @end

将UISegmentedControl控件的Class改为刚创建的处理类：SegmentedControl，然后，将UISegmentedControl控件关联到四个输出口：view分别关联到刚创建的三个view上，viewController关联到File's Owner上。

Ios代码 ![收藏代码][icon_star.png]

1.  \- (void)awakeFromNib\{
2.  \[\[NSNotificationCenter defaultCenter\] addObserver:self
3.  selector:@selector(switchViews:)
4.  name:@"switchViews" 
5.  object:nil\];
6.  \}
7.  
8.  \- (void)switchViews:(NSNotification\*)notification\{
9.  NSNumber \*viewNumber = \[notification object\];
10. NSInteger i = \[viewNumber integerValue\];
11. \[self setSelectedSegmentIndex:i\];
12. UIView \*chosenView = nil;
13. switch (i) \{
14. case 0: 
15. chosenView = view1;
16. break;
17. case 1: 
18. chosenView = view2;
19. break;
20. case 2: 
21. chosenView = view3;
22. break;
23. default:
24. break;
25. \}
26. if (chosenView) \{
27. \[\[viewController view\] bringSubviewToFront:chosenView\];
28. \}
29. \}
30. 
31. \- (void)dealloc\{
32. \[super dealloc\];
33. \[\[NSNotificationCenter defaultCenter\] removeObserver:self\];
34. \}
