[window addSubview:splitViewController.view]; [window makeKeyAndVisible]; return YES; }修改MainWindow.xib文件添加UISplitViewController容器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最后在把相应的容器换成自定义的容器实现的方法是最后的结果是现在我们在实现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 .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 { indexsender; self.lable.text[NSString stringWithFormat:Row %d,section %d,[index row],[index section]]; if ([index row]%20) { self.switch1.onYES; }else { self.switch1.onNO; } } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { [super viewDidUnload]; self.lablenil; self.switch1nil; } - (void)dealloc { [self.lable release]; [self.switch1 release]; [super dealloc]; } end 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。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.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]; }2、修改相应的xib文件相应的事件和控件相联系。运行结果如下
