iPad的屏幕比iPhone大，所以在界面上，iPad比iPhone多一个UISplitViewController，用来实现iPad在横屏时，分两栏显示所需要的界面，可以一边是目录一边是具体的内容。下面我将详细的阐述UISplitViewController在ipad中的使用。

首先是创建一个工程：iPad.demo.

<IGNORE_JS_OP style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; FONT: 14px/21px Tahoma, 'Microsoft Yahei', Simsun; WORD-WRAP: break-word; WHITE-SPACE: normal; ORPHANS: 2; LETTER-SPACING: normal; COLOR: rgb(68,68,68); WORD-SPACING: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px"> 


然后创建一个DetailViewController和RootViewController，其中RootViewController继承UITableViewController。同事创建两个相应的xib文件。删除ipad_demoViewController.相应的类列表如下：

<IGNORE_JS_OP style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; FONT: 14px/21px Tahoma, 'Microsoft Yahei', Simsun; WORD-WRAP: break-word; WHITE-SPACE: normal; ORPHANS: 2; LETTER-SPACING: normal; COLOR: rgb(68,68,68); WORD-SPACING: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px"> 


然后修改ipad_demoAppDelegate：

.h文件：

1. #import <UIKit/UIKit.h> 
2. #import "RootViewController.h" 
3. #import "DetailViewController.h" 
4. @class ipad_demoViewController;
6. @interface ipad_demoAppDelegate : NSObject <UIApplicationDelegate> {
    
7.     UIWindow *window; 
8.    UISplitViewController *splitViewController; 
9.     RootViewController *rootViewController; 
10.     DetailViewController *detailViewController; 
11. }
13. @property (nonatomic, retain) IBOutlet UIWindow *window; 
14. @property (nonatomic, retain) IBOutlet UISplitViewController *splitViewController; 
15. @property (nonatomic, retain) IBOutlet RootViewController *rootViewController; 
16. @property (nonatomic, retain)  IBOutlet DetailViewController *detailViewController; 
17. @end

复制代码

.m文件：

1. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
2.     // Override point for customization after app launch. 
3.     [window addSubview:splitViewController.view]; 
4.     [window makeKeyAndVisible];
6.     return YES; 
7. }

复制代码

修改MainWindow.xib文件：

添加UISplitViewController容器：

<IGNORE_JS_OP style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; FONT: 14px/21px Tahoma, 'Microsoft Yahei', Simsun; WORD-WRAP: break-word; WHITE-SPACE: normal; ORPHANS: 2; LETTER-SPACING: normal; COLOR: rgb(68,68,68); WORD-SPACING: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px"> 


IB中的控件和相应的事件相联系：连接过程是按住control键，然后点击ipad_demo App Delegate，连接到Split View Controller，然后选择自定义的事件即可，最后的结果如下：

<IGNORE_JS_OP style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; FONT: 14px/21px Tahoma, 'Microsoft Yahei', Simsun; WORD-WRAP: break-word; WHITE-SPACE: normal; ORPHANS: 2; LETTER-SPACING: normal; COLOR: rgb(68,68,68); WORD-SPACING: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px"> 


最后在把相应的容器换成自定义的容器：实现的方法是

<IGNORE_JS_OP style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; FONT: 14px/21px Tahoma, 'Microsoft Yahei', Simsun; WORD-WRAP: break-word; WHITE-SPACE: normal; ORPHANS: 2; LETTER-SPACING: normal; COLOR: rgb(68,68,68); WORD-SPACING: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px"> 


最后的结果是：

<IGNORE_JS_OP style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; FONT: 14px/21px Tahoma, 'Microsoft Yahei', Simsun; WORD-WRAP: break-word; WHITE-SPACE: normal; ORPHANS: 2; LETTER-SPACING: normal; COLOR: rgb(68,68,68); WORD-SPACING: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px"> 


现在我们在实现DetailViewController：

首先修改其相应的文件：
.h文件修改如下：

1. #import <UIKit/UIKit.h> 
2. @interface DetailViewController : UIViewController {
    
3.    IBOutlet UILabel *lable; 
4.     IBOutlet UISwitch *switch1; 
5.     NSIndexPath *index; 
6. } 
7. -(void)deetail:(id)sender; 
8. @property (nonatomic,retain) UILabel *lable; 
9. @property (nonatomic,retain) UISwitch *switch1; 
10. @end

复制代码

.m文件修改如下：

1. #import "DetailViewController.h" 
2. @implementation DetailViewController 
3. @synthesize lable,switch1; 
4. - (void)viewDidLoad {
    
5.     [super viewDidLoad]; 
6. } 
7. -(void)viewWillAppear:(BOOL)animated 
8. {
10. } 
11. -(void)deetail:(id)sender 
12. {
     
13.     index=sender; 
14.     self.lable.text=[NSString stringWithFormat:@"Row %d,section %d",[index row],[index section]]; 
15.     if ([index row]%2==0) {
     
16.         self.switch1.on=YES; 
17.     }else {
     
18.         self.switch1.on=NO; 
19.     } 
20. } 
21. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
     
22.     return YES; 
23. } 
24. - (void)didReceiveMemoryWarning {
     
25.     [super didReceiveMemoryWarning]; 
26. } 
27. - (void)viewDidUnload {
     
28.     [super viewDidUnload]; 
29.     self.lable=nil; 
30.     self.switch1=nil; 
31. } 
32. - (void)dealloc {
     
33.     [self.lable release]; 
34.     [self.switch1 release]; 
35.     [super dealloc]; 
36. } 
37. @end

复制代码

2.修改相应的xib文件：

添加相应的控件，并且相应的组建和相应的事件相关联。

<IGNORE_JS_OP style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; FONT: 14px/21px Tahoma, 'Microsoft Yahei', Simsun; WORD-WRAP: break-word; WHITE-SPACE: normal; ORPHANS: 2; LETTER-SPACING: normal; COLOR: rgb(68,68,68); WORD-SPACING: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px"> 


最后我们实现RootViewController：

首先修改相应的文件：
.h文件如下：

1. #import <UIKit/UIKit.h> 
2. @class DetailViewController; 
3. @interface RootViewController : UITableViewController {
5.    IBOutlet DetailViewController *detailViewController; 
6. } 
7. @property (nonatomic,retain) DetailViewController *detailViewController; 
8. @end

复制代码

.m文件如下：

1. - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    
2.     // Return the number of sections. 
3.     return 2; 
4. }
6. - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    
7.     // Return the number of rows in the section. 
8.     return 7; 
9. }
11. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
     
12.     static NSString *CellIdentifier = @"Cell"; 
13.     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
14.     if (cell == nil) {
     
15.         cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 
16.     } 
17.     // Configure the cell… 
18.     cell.textLabel.text=[NSString stringWithFormat:@"ROW %d section %d",[indexPath row],[indexPath section]]; 
19.     return cell; 
20. }
22. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
     
23.     // Navigation logic may go here. Create and push another view controller. 
24.     // DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil]; 
25.     // [self.navigationController pushViewController:detailViewController animated:YES]; 
26.     // [detailViewController release]; 
27.    [detailViewController deetail:indexPath]; 
28. }

复制代码

2、修改相应的xib文件：

相应的事件和控件相联系。

<IGNORE_JS_OP style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; FONT: 14px/21px Tahoma, 'Microsoft Yahei', Simsun; WORD-WRAP: break-word; WHITE-SPACE: normal; ORPHANS: 2; LETTER-SPACING: normal; COLOR: rgb(68,68,68); WORD-SPACING: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px"> 


运行结果如下：

<IGNORE_JS_OP style="WIDOWS: 2; TEXT-TRANSFORM: none; BACKGROUND-COLOR: rgb(255,255,255); TEXT-INDENT: 0px; FONT: 14px/21px Tahoma, 'Microsoft Yahei', Simsun; WORD-WRAP: break-word; WHITE-SPACE: normal; ORPHANS: 2; LETTER-SPACING: normal; COLOR: rgb(68,68,68); WORD-SPACING: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px">
