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:
- #import <UIKit/UIKit.h>
- #import "RootViewController.h"
- #import "DetailViewController.h"
- @class ipad_demoViewController;
- @interface ipad_demoAppDelegate : NSObject <UIApplicationDelegate> {
- UIWindow *window;
- UISplitViewController *splitViewController;
- RootViewController *rootViewController;
- DetailViewController *detailViewController;
- }
- @property (nonatomic, retain) IBOutlet UIWindow *window;
- @property (nonatomic, retain) IBOutlet UISplitViewController *splitViewController;
- @property (nonatomic, retain) IBOutlet RootViewController *rootViewController;
- @property (nonatomic, retain) IBOutlet DetailViewController *detailViewController;
- @end
复制代码
.m文件:
- - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
- // Override point for customization after app launch.
- [window addSubview:splitViewController.view];
- [window makeKeyAndVisible];
- return YES;
- }
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:
- #import <UIKit/UIKit.h>
- @interface DetailViewController : UIViewController {
- IBOutlet UILabel *lable;
- IBOutlet UISwitch *switch1;
- NSIndexPath *index;
- }
- -(void)deetail:(id)sender;
- @property (nonatomic,retain) UILabel *lable;
- @property (nonatomic,retain) UISwitch *switch1;
- @end
复制代码
.m文件修改如下:
- #import "DetailViewController.h"
- @implementation DetailViewController
- @synthesize lable,switch1;
- - (void)viewDidLoad {
- [super viewDidLoad];
- }
- -(void)viewWillAppear:(BOOL)animated
- {
- }
- -(void)deetail:(id)sender
- {
- index=sender;
- self.lable.text=[NSString stringWithFormat:@"Row %d,section %d",[index row],[index section]];
- if ([index row]%2==0) {
- self.switch1.on=YES;
- }else {
- self.switch1.on=NO;
- }
- }
- - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
- return YES;
- }
- - (void)didReceiveMemoryWarning {
- [super didReceiveMemoryWarning];
- }
- - (void)viewDidUnload {
- [super viewDidUnload];
- self.lable=nil;
- self.switch1=nil;
- }
- - (void)dealloc {
- [self.lable release];
- [self.switch1 release];
- [super dealloc];
- }
- @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:
- #import <UIKit/UIKit.h>
- @class DetailViewController;
- @interface RootViewController : UITableViewController {
- IBOutlet DetailViewController *detailViewController;
- }
- @property (nonatomic,retain) DetailViewController *detailViewController;
- @end
复制代码
.m文件如下:
- - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
- // Return the number of sections.
- return 2;
- }
- - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
- // Return the number of rows in the section.
- return 7;
- }
- - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
- static NSString *CellIdentifier = @"Cell";
- UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
- if (cell == nil) {
- cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
- }
- // Configure the cell…
- cell.textLabel.text=[NSString stringWithFormat:@"ROW %d section %d",[indexPath row],[indexPath section]];
- return cell;
- }
- - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
- // Navigation logic may go here. Create and push another view controller.
- // DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
- // [self.navigationController pushViewController:detailViewController animated:YES];
- // [detailViewController release];
- [detailViewController deetail:indexPath];
- }
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">
